Abstract

50

Background: The circulating immune phenotype was defined in adults and

51

young children with early atopic dermatitis/AD, but chronologic changes in blood

52

of AD infants and children through adolescence have not been explored.

53

Objective: To compare immune activation and cytokine polarization in blood of

54

0-5y/o (n=39), 6-11y/o (n=26), 12-17y/o (n=21) and ≥18y/o (n=43) patients with

55

AD vs. age-matched controls.

56

Methods: Flow cytometry was used to measure interferon-γ, interleukin (IL)-9,

57

IL-13, IL-17, and IL-22 cytokines in CD4+/CD8+ T-cells, with ICOS and HLA-DR

58

defining mid- and long-term T-cell activation, respectively, within skin-

59

homing/CLA+ vs. systemic/CLA- T-cells. Unsupervised clustering differentiated

60

patients based on their blood biomarker frequencies.

61

Results: While CLA+ Th1 frequencies were significantly lower in infants with AD

62

vs. all older patients (P<0.01), CLA+ Th2 T-cells were similarly expanded across

63

all AD age groups compared with controls (P<0.05). After infancy, CLA- Th2

64

frequencies were increased in AD in all age groups, suggesting systemic immune

65

activation with disease chronicity. IL-22 frequencies serially increased from

66

normal in infants to highly significant levels in adolescents and adults compared

67

to respective controls (P<0.01). Unsupervised clustering aligned the AD profiles

68

along an age-related spectrum from infancy to adulthood (ICOS, IL-22 etc.).

69

Conclusions: The adult AD phenotype is achieved only in adulthood. Unique

70

cytokine signatures characterizing individual pediatric age endotypes may require

71

age-specific therapies. Future longitudinal studies, comparing the profile of

5 72

cleared vs. persistent pediatric AD, may define age-specific changes that predict

73

AD clearance.

74 75

Capsule Summary: Decreased Th1/Th2 ratio characterizes the atopic dermatitis

76

(AD) phenotype across all age groups, while chronic activation, IL-9, IL-22, and

77

Treg changes characterize older patients. Even the adolescent AD profile differs

78

from adult AD.

79 80

Clinical Implications: Diverse immune signatures in different pediatric and adult

81

atopic dermatitis age groups argue for age-specific, rather than uniform,

82

therapeutic interventions.

Introduction

119

Infancy, childhood and adolescence are critical periods for immune system

120

maturation.1 Early abnormal immune development may cause immune-related

121

disorders. Indeed, 85% of atopic dermatitis (AD) cases present before 5 years of

122

age.2 While young adults have a different AD phenotype from elderly patients,3

123

immune changes in AD between early childhood and adulthood are unknown.4

124

Blood studies that dissect developmental changes from infancy through

125

adulthood are limited and primarily focused on T-helper (Th)1/Th2 subsets.

126

Some studies with healthy controls showed expansion of Th1/Th2/T-cytotoxic

127

(Tc)1 subsets with age,5, 6 while others reported no changes in Th2/Tc2 over

128

time.7 Immature interferon (IFN)-γ response8 and low Th1/Tc1 frequencies9-11

129

were seen in early stages of normal development, and abnormal Th1/Th2 ratios

130

in cord blood and infants who develop AD were described.12-14 However, few

131

studies compared pediatric and adult AD populations6, 15-17 and none directly

132

compared consecutive age groups of AD with age-matched controls, which is

133

critical in understanding normal vs. pathological development of acquired

134

immunity.

135

The therapeutic arsenal available for 0-12 year old (y/o) AD patients is

136

limited to topical agents and/or broad systemic immune suppressants.4, 18 Active

137

development of targeted therapeutics is ongoing for adults and adolescents with

138

AD and will eventually move to children, further necessitating the elucidation of

139

pediatric endotypes at successive pre-adult age groups to introduce safe,

140

effective, age-tailored targeted approaches.19

8 141

We compared T-cell memory subset activation and polarized CD4/CD8

142

subset frequencies within the skin-homing/cutaneous lymphocyte antigen/CLA+

143

and systemic/CLA- compartments, in the blood of infants and toddlers (0-5y/o),

144

young children (6-11y/o), adolescents (12-17y/o) and adults (≥18y/o) with

145

moderate-to-severe AD. To differentiate pathologic from physiologic immune

146

maturation, age-matched healthy controls were included. We found that

147

decreased Th1/Th2 ratios were shared across all AD ages, but unique

148

fingerprinting characterizes individual AD age groups, differentiating them from

149

their age-matched peers. Our intracellular and T-cell blood biomarker data

150

grouped the AD cohort, but not the controls, into three unique age phenotypes

151

aligned along a spectrum.

152 153

Methods

154

Patient characteristics and blood samples

155

Blood was obtained (with signed Institutional Review Board-approved informed

156

consent from parents and patients 12 years and older) from 39 infants and

157

toddlers (0-5y/o; mean 23 months), 26 children (6-11y/o; mean 7.5yrs), 21

158

adolescents (12-17y/o; mean 14.9yrs) and 43 adults (≥18y/o; mean 43yrs) with

159

moderate-to-severe AD, as well as healthy age-matched controls (24-30 in each

160

group; demographic and laboratory data in Table E1). Sensitivity analyses on

161

patient subsets who were matched for all demographic parameters yielded

162

similar results to analysis including all subjects (Table E2A-B).

9 163

Disease severity was scored using SCORing of AD (SCORAD) for adults and

164

SCORAD, Eczema Area and Severity Index (EASI), and Atopic Dermatitis

165

Quickscore (ADQ) in those less than 18y/o. ADQ is a parent-administered tool,

166

which assesses involvement and pruritus of 7 body parts and highly correlates

167

with SCORAD.20 In subjects <18y/o, eosinophil counts and skin-barrier

168

assessment through transepidermal water loss (TEWL) of lesional (LS) and non-

169

lesional (NL) arm skin (AquaFlux Model AF200; Biox, London, England)21 were

170

measured when feasible. No patients received systemic immunosuppressive

171

treatment within 4 weeks prior to this study, thus the data present baseline

172

immune phenotyping of the studied populations. Concomitant allergic

173

manifestations were recorded, and individuals were classified as either having

174

general allergies (allergic rhinitis/asthma/allergic conjunctivitis/environmental),

175

food allergies (FA), both, and neither. Controls had no personal history of AD.

176

Only 1 child and 5 adolescent controls had history of non-cutaneous atopic

177

manifestations, however sensitivity analysis excluding these subjects did not alter

178

the results (Table E2C).

179

Isolation of Peripheral Blood Mononuclear Cells (PBMCs)

180

PBMCs were isolated from whole blood by Ficoll-Paque Plus (GE Healthcare,

181

Sweden). Briefly, the blood was laid under Ficoll gradient; after spinning, PBMCs

182

were collected at the interface between the plasma and the Ficoll gradient (see

183

Methods in the Online Repository/OR).

184

Stimulation of blood cell populations for cytokine responses

10 185

Ex-vivo cell activation is required to detect cytokine production, as less than 1%

186

of non-stimulated cells produce cytokines. Whole blood was incubated with PMA

187

(25ng/ml) plus ionomycin (2µg/ml) in the presence of brefeldin A (10µg/ml) for 4

188

hours at 37ºC to induce cytokine responses. After stimulation, red blood cells

189

were lysed with FACS lysing solution to obtain leukocytes (see Methods in the

190

OR).

191

Cell surface staining and intracellular staining on PBMCs and stimulated

192

and non-stimulated CD4/CD8 T-cells

193

Peripheral blood mononuclear cells/PBMCs were stained with fluorochrome-

194

labeled Abs to cell surface markers (CD3, CD8, CD4, CD45RO, CCR7, ICOS,

195

HLA-DR, CLA, CCR4, CD25, CD127). Stimulated and non-stimulated blood cells

196

were also stained for cell surface markers [CD3, CD4, and CLA (CD8+ T-cells

197

were gated thorough CD3+CD4- T subpopulation] and permeabilized with

198

FACS/perm to stain for cytokines including Interleukin (IL)-13, IL-22, IL-9, IFN-γ

199

and IL-17 (see Methods in the OR).

200

Statistical analysis

201

Statistical analyses were performed with R software (www.R-projets.org). Means

202

and medians were compared using the Welch t-test and Wilcoxon-Mann-Whitney

203

test, respectively. Unsupervised hierarchical clustering of variables (T-cell subset

204

frequencies, age, and clinical scores) was performed using the R package

205

“hclust,” with a McQuitty agglomeration algorithm and Spearman coefficient as a

206

similarity metric and presented as a heat map and a dendrogram. Individual

207

scatter plots were constructed that display Spearman coefficients, 95%

11 208

confidence intervals, and p-values for AD and healthy samples. We performed k-

209

means unsupervised clustering across principal components of the frequencies

210

of all AD and separately among all healthy control subsets. We found that 3

211

clusters separated AD patients, but not controls, along a chronologic age

212

spectrum. ANOVA, in conjunction with the Tukey test, was used to find markers

213

that differentiated any two clusters. P-values and fold-changes (FCH) were

214

designated as ***(p<0.001), **(p<0.01), *(p<0.05), and +(p<0.1).

215

We also performed a power calculation based on our previous flow

216

cytometry study on moderate-to-severe adult AD patients.22 We determined that

217

39 AD patients would have greater than 90% power (at a significance level of

218

0.05) to detect differences versus controls in various inflammatory cell subsets

219

(CD4+IL-22+CLA+, CD4+IL-13+CLA-, CD8+IL-17+CLA+, CD8+ Tcm HLA-

220

DR+CLA+).

221 222

Results

223

Flow cytometry was used to measure frequencies of IFN-γ, IL-9, IL-13, IL-17A

224

and IL-22-polarized T-cells, defining Th1/Tc1, Th9/Tc9, Th2/Tc2, Th17/Tc17 and

225

Th22/Tc22 subsets in CD4+/CD8+ T-cells, respectively. Cell surface staining was

226

used to assess expression of mid (inducible co-stimulator molecule/ICOS) and

227

late (HLA-DR) activation markers in central (Tcm/CCR7+CD45RO+) and effector

228

(Tem/CCR7-CD45RO+) memory T-cells in skin homing/cutaneous/CLA+ and

229

systemic/CLA- compartments.

12 230

Patients and controls were divided into 4 consecutive age groups (infants

231

and toddlers 0-5y/o, children 6-11y/o, adolescents 12-17y/o and adults ≥18y/o).

232

To display both healthy vs. pathologic developmental changes and immune

233

abnormalities within each age group vs. controls, we present two types of

234

comparison plots; both contain similar data but focus on either AD patients vs.

235

controls for each age group or AD vs. control across all ages. To better represent

236

the effect of values distribution, the comparison plots presented below contain

237

both the mean (in black) and the median (in red) +/- standard error, and their

238

respective p-values. Results discuss the mean values, while median percentages

239

for main comparisons discussed are presented in Table E3.

240

Skin-homing memory T-cell expansion and ICOS activation feature early

241

AD

242

Tcm and Tem T-cells are main components of the adaptive immune system,

243

harboring distinct homing capacities.23 While both express the skin homing

244

marker CLA, only Tcm cells retain CCR7 positivity, which enables them to

245

migrate into lymph nodes and function as an immunologic reserve.24 After gating

246

on CD3+ viable T-cells using flow cytometry, CD3+CD4+ and CD3+CD8+ were

247

defined and analyzed separately. CCR7 and CD45RO were used to differentiate

248

memory subsets within the CD4 and CD8 populations. CCR7+CD45RO- defined

249

naïve cells, CCR7+CD45RO+ central memory T-cells (Tcm), CCR7-CD45RO+

250

effector memory T-cells (Tem) and CCR7-CD45RO- Effector/Temra/terminally

251

differentiated T-cells (Fig. E1A-C). We then further defined activated ICOS/HLA-

13 252

DR activated Tcm/Tem memory subset, using CLA to segregate skin-homing

253

(CLA+) versus systemic subsets (CLA-).

254

Normal development was characterized by a slight drop of CLA+ CD4+Tem (but

255

not Tcm) cells between infancy and childhood (infants 26.7% vs. children 19%,

256

P=0.01; Figs. 1A-B, E1D-E), but this decrease was significantly more evident in

257

AD (P<0.05; Figs. 1A-B, E1D-E). CD4+CLA+ Tem/Tcm cells were significantly

258

higher in AD infants (Tcm: 20.4% vs. 13.4%, P=0.006; Tem: 38% vs. 26.7%,

259

P=0.002; Fig. E1D-E) and children (Tcm: 18.8% vs. 11.3%, P=0.01; Tem: 27.7%

260

vs. 19%, P=0.03; Fig. E1D-E) than controls, a difference that diminished with

261

increasing age. T-cell memory subset fluctuations with age are presented in

262

Figure E2. Due to increased proportions of effector and naïve cells, CD8+

263

Tcm/Tem subsets dropped between infancy and childhood exclusively in controls

264

(Tcm: infants 12.8% vs. children 5.6%, P=0.008; Tem: infants 15.4% vs. children

265

5%, P<0.001; Fig. 1C-D), leading to higher frequencies in children with AD

266

(P<0.01), but otherwise frequencies were overall similar between AD and

267

controls over time (Fig. E1F-G). Significant CD4+/CD8+ effector cells increase

268

with age characterized AD vs. controls, who showed decrease of this subset

269

during the years (Fig. E2J, L).

270

CD4+ Tcm/Tem ICOS mid-activation continuously increased in both

271

controls and AD, however it decreased significantly between adolescence and

272

adulthood, exclusively in controls (Tcm CLA+: 24% vs. 9%, P=0.003; CLA-: 9.2%

273

vs. 3.7%, P=0.001; Fig. 1E-H). Both skin-homing/CLA+ and systemic/CLA- ICOS-

274

activated CD4+ T-cell frequencies were significantly increased in infants and

14 275

adults with AD vs. respective controls (P<0.05; Fig. 1E-H). Skin-homing CD8+

276

Tcm/Tem ICOS activation increased gradually, most notably in AD patients (Fig

277

1I-L), with frequency differences uniquely seen in adults with AD vs. controls

278

(Tcm: 18.4% vs. 12.5%, P=0.01; Tem: 26% vs. 13.4%, P<0.001; Fig. 1I-L).

279

The HLA-DR antigen, indicating chronic activation,25 had similar (or even

280

lower) expression in infants with and without AD (P>0.1; Fig. E1H-K), but started

281

to rise in AD children (Tcm+CD4+CLA+ AD: 15.8% vs. 8.4%, P=0.02; CLA-: 7.2%

282

vs. 2.8%, P=0.06; Fig. E1H-I), reaching consistently high levels across

283

CD4+/CD8+/CLA+/CLA-/Tcm/Tem cells in adults with AD compared to healthy

284

individuals (P<0.05; CD8+ Tcm/Tem data not shown; Fig. E1H-K).

285

Decreased Th1/Th2 ratio characterizes AD across ages

286

Since T-cell activation leads to cytokine polarization we next studied different

287

polar T-cell subsets. Representative flow cytometry plots and gating strategy are

288

presented in Figure E3. Congruent with past publications,9, 10 IFN-γ levels

289

increased with age in both control and AD subjects, with the lowest frequencies

290

seen in infants (Fig. 2A-D). Nevertheless, in AD IFN-γ did not reach control

291

levels, particularly within the skin homing compartment (CD4+CLA+: infants

292

control 12% vs. AD 7.7%, P=0.04; children control 19.5% vs. AD 13.6%, P=0.05;

293

adolescents control 18% vs. AD 13%, P=0.07) until adulthood (P=0.2; Figs. 2A-

294

D, E4A-D). Even in adulthood, levels trended towards lower frequencies.

295

Interestingly, the only population that showed lower systemic/CLA- CD4+/CD8+

296

IFN-γ was the 5-12y/o age group (CD4+: control 20% vs. AD 14%, P=0.04; CD8+:

297

control 39% vs. AD 28%, P=0.05; Fig. E4B, D).

15 298

In controls, IL-13+CD4+CLA+ was lowest in infants, reaching a plateau in

299

childhood. Conversely, in AD patients, levels were similarly elevated across all

300

ages (P>0.1; Fig. 2E). Systemic/CLA- Th2 was overall low in controls (Fig. 2F).

301

Levels were significantly higher in AD than controls in children (2.8% vs. 0.6%,

302

P=0.005; Fig. E4F), adolescents (1.5% vs. 0.7%, P=0.006; Fig. E4F) and adults

303

(1.3% vs. 0.7%, P=0.005; Fig. E4F). While Tc2 cells were slightly higher in

304

children with vs. without AD, differences in CD8+ subsets were more prominent in

305

adulthood (Figs. 2G-H, E4G-H). Reflecting the Th1 and Th2 imbalances

306

characterizing AD, the Th1/Th2 ratio was decreased in AD than controls in both

307

CLA+/CLA- subsets across the ages. Tc1/Tc2 was significantly lower in children

308

and adults with AD vs. controls (Figs. 2I-L, E4I-L).

309

Both healthy controls and AD patients showed Th9 increases over time,

310

peaking in adolescence and dropping in adulthood (Figs. 3A-B, E5A-B). No Th9

311

differences were observed between AD and controls, besides 5-12y/o children

312

with AD that showed significantly increased CLA- levels (0.76% vs. 0.3%,

313

P=0.04; Fig. E5B). This AD age group also showed increased CLA+/CLA- Tc9

314

levels (Figs. 3C-D, E5C-D). CLA+ Th17 cells were generally stable and similarly

315

abundant across ages among control and AD (Figs. 3E, E5E), contrary to CLA-

316

Th17 cells which showed developmental expansion in both (Figs. 3F, E5F).

317

Contrary to adolescents with AD that had lower CLA+ Tc17 than controls (1% vs.

318

4.7%, P=0.04), adults had significantly higher frequencies (2.1% vs. 1.4%,

319

P=0.05; Figs. 3G-H, E5G-H). Systemic/CLA- CD4+/CD8+ IL-22+ similarly

320

increased with age in both controls and AD (Fig. 3J, 3L, E5J, E5L), while skin-

16 321

homing Th22/Tc22 cells increased with age, primarily in AD (Figs. 3I, 3K, E5I,

322

E5K). Starting in childhood, skin-homing Th22/Tc22 were significantly higher in

323

AD vs. controls, and incrementally increased with age (Th22: children 6.7% vs.

324

4%, P=0.07; adolescents 7.9% vs. 3.6%, P=0.001; adults 8.2% vs. 4.4%,

325

P<0.0001; Figs. 3I, 3K, E5I, E5K). Polar T-cell subset development in controls

326

and AD is summarized in Table E6 and illustrated in the graphical abstract.

327

The unsupervised hierarchical clustering heatmap in Figure 4 summarizes

328

the above, displaying all polarized T-cell subsets for control and AD across age

329

groups (red: positive/increase; blue: negative/decrease). Fold-changes (FCHs) of

330

the mean frequencies of AD vs. controls for each age group are presented (stars

331

and plus signs display significance). The green cluster includes subsets that

332

were relatively low and stable among controls, but incrementally increased with

333

age in AD. Most of these subsets were significantly increased in adults with AD

334

vs. controls (FCH>1.57, P<0.05), while younger AD patients showed lower or no

335

significance. The pink box shows increased IL-9 frequencies in childhood, which

336

decline in adulthood, particularly in AD. The yellow cluster shows markers that

337

increased in both controls and AD, therefore minimizing the differences between

338

groups.

339

T-cell activation, clinical measures and IFN-γ are associated with age and

340

AD chronicity

341

We also evaluated how clinical characteristics, including AD severity (SCORAD,

342

EASI), patient age, disease duration, eosinophil counts, pruritus and TEWL relate

343

to different polar T-cell subsets. Unsupervised hierarchical clustering of all T-cell

17 344

subset frequencies, clinical scores, AD duration and age was performed using

345

Spearman correlations as a similarity metric, as displayed in the correlation

346

heatmap and dendrogram in Figure 5 (red: positive correlation; blue: negative

347

correlation, stars and plus signs display significance). Congruent with recent AD

348

data,22, 26 which showed positive correlations between IL-13- and IL-22- and

349

between IL-17- and IL-22-producing T-cells,22, 26, 27 these cytokines largely

350

grouped together (turquoise rectangle). IFN-γ-producing T-cells clustered

351

together with AD duration and patient age (yellow rectangles). A tight cluster

352

gathering multiple clinical measures (green rectangles) was located adjacent to

353

IL-9/IL-13-producing T-cells (purple rectangles). Significant correlations depicted

354

in this heatmap are listed in Table E4, with selected individual scatter plots

355

presented in Figures 6-7 and E6-E8.

356

SCORAD and EASI were positively correlated (r=0.74, P<0.001; Fig. 6A).

357

SCORAD also correlated with skin-homing CD4+ cells (r=0.24, P=0.0016; Fig.

358

6B), pruritus (r=0.54, P<0.0001, Fig. 6C) and eosinophils (r=0.25, P=0.001; Fig.

359

6D). To evaluate normal vs. pathologic development with age, we

360

comprehensively assessed age correlations in control and AD subjects,

361

presenting both on the same scatter plots for clarity, when applicable. Age

362

correlated positively with severity by SCORAD (r=0.25, P=0.0016; Fig. 6E) and

363

EASI (r=0.34, P<0.001; Fig. 6F), and with all other clinical measures, including

364

pruritus (Fig. 6G), eosinophils (Fig. 6H), and lesional TEWL (Fig. 6I-J).

365 366

While skin homing Tcm/Tem cells correlated negatively with age (red=AD, blue=controls; Fig 6K-L), the proportion of ICOS and HLA-DR-activated skin-

18 367

homing T-cells increased exclusively in AD (Fig. E6A-D). AD duration, which

368

highly correlated with patients’ age (r=0.98, P<0.0001; Fig. E6E), also

369

demonstrated significant positive correlations with EASI and pruritus (Fig. E6F-

370

H). Among the cytokine subsets (Fig. E6I-L), the most significant correlation was

371

noted between AD duration and IFN-γ-producing cells (r=0.58, P<0.0001; Fig.

372

E6L).

373

Overall IFN-γ increased with age in both AD and controls (Fig. E7A-D),

374

however, although the Th1/Th2 (but not the Tc1/Tc2) ratio, and particularly its

375

skin-homing component, increased with age in both groups, it remained

376

significantly decreased in AD across all ages vs. controls (Fig. 7A-D).

377

Conversely, differences between AD and controls were observed in skin-homing

378

Th2/Tc2 throughout development, with controls never reaching AD levels (Fig.

379

7E-H). CLA+ Th22/Tc22 showed significantly higher developmental increases in

380

AD (Fig. 7I, K), while systemic subsets generally overlapped (Fig. 7J, L). Similar

381

negative trends of IL-9+ (Fig. E7E-H), and expansion of systemic Th17 cells were

382

seen in controls and AD subjects (Fig. E7I-L).

383

Positive correlations between SCORAD and IL-13, IL-9 and IL-22-

384

producing cells were recorded (P<0.02; Fig. E8A-C). EASI correlated with Th9,

385

Th22 and pruritus (P<0.03; Fig. E8D-F), while pruritus was associated with Th22

386

and eosinophil counts (P<0.032; Fig. E8G-H). TEWL correlated with CD4+CLA+

387

cells, only in non-lesional skin (Fig. E8I-J). Th22 positively correlated with TEWL

388

in lesional tissues (Fig. E8K-L), and AD severity correlated with TEWL in non-

389

lesional skin (Fig. E8M-P).

19 390

Because Foxp3 staining requires cell permeabilization, surface markers

391

were used for Treg identification. 90% of CD25+CD127-CCR4+ cells co-express

392

Foxp3, therefore CD25+CD127-CCR4+ phenotype defined Tregs.28 In analyzing

393

T-regulatory cells (Tregs), both total Treg (CD25+CD127-) and skin-homing

394

(CCR4+CLA+ fraction) Treg frequencies were captured. The only AD age group

395

that showed significant increases of both total (Fig. E9A) and skin-homing (Fig

396

E9B) Tregs vs. control was 5-12y/o (P<0.01). Developmentally, AD showed

397

similar total Treg trends as controls, whereas discrepancies were more evident in

398

skin-homing subsets (Fig. E9C-D).

399

Cytokine polarization and T-cell activation differentiate AD patients into

400

separate age clusters along a spectrum

401

We integrated the T-cell and cytokine biomarkers to differentiate the entire AD

402

cohort based on their blood phenotype. The principal components of all

403

biomarker data for all subjects were analyzed using unsupervised k-means

404

clustering, separately for AD patients and controls. As illustrated in Figure 8, in

405

the AD cohort, the frequencies of different markers defined three meaningful

406

clusters, aligning along a spectrum. While infants (pink ellipse) clustered on the

407

far left, and adults (green ellipse) on the right, children and adolescents (blue

408

ellipse) generally clustered together, between the infants and adults. The

409

markers that best distinguished between each set of clusters appear in the boxes

410

between the two cohorts and are summarized in Table E5. Th1/Th2 ratio, CD8+

411

activation and IFN-γ-producing T-cells differentiated adults from younger groups.

412

Tregs, T-cell activation, and different cytokine subsets were able to differentiate

20 413

distinctive AD age groups. Applying the same model to the control population did

414

not distinguish between age groups (Fig. 8).

415 416

Discussion

417

This is the first comprehensive study that compares systemic immune profiles of

418

different AD age groups (0-5y/o, 6-11y/o, 12-17y/o and ≥18y/o), with appropriate

419

comparisons to controls. Since circulating CLA+ T-cells have been suggested as

420

peripheral biomarkers in AD,29 we utilized CLA to segregate between skin-

421

homing and systemic immune changes that accompany healthy and AD

422

development. Our data suggest unique endotypes in infants and toddlers,

423

children, adolescents and adults with AD, possibly advocating for personalized,

424

endotype-driven approaches rather than “one-size-fits-all” therapeutic strategies.

425

In addition, the results start to define age-specific differences between pediatric

426

AD patients and age-matched controls as a complement to our recent data

427

showing differences between elderly vs. young AD adult endotypes.3 Our data

428

suggest that even adolescents have a different profile from adults, possibly

429

contributing to the somewhat lower response to the recently approved IL-4Rα

430

antagonist, dupilumab, in adolescents vs. adults.30, 31

431

Immune responses at birth are immature10 with decreases of naïve T-cells

432

in healthy children with increasing age, paralleled by increases in Tcm/Tem

433

cells.32 Skin-homing Tcm/Tem cells are higher in infants and children with AD

434

compared to controls and decrease with age, exclusively in AD. Elevated skin-

435

homing memory cells cluster AD infants separately from other age groups,

21 436

suggesting early relevance. Excessive naïve-to-memory switch, which causes an

437

influx of memory cells into the circulation in infancy and early childhood, may play

438

a role in AD initiation, while exclusive decreases in the AD population over time

439

may suggest increased migration of CLA+ Tcm/Tem cells to skin.

440

ICOS is involved in multiple adaptive immune responses, including

441

induction of various T-cell polarizations,33-35 Treg regulation,36 antibody

442

responses (including IgE switching),37 and innate lymphoid cell (ILC)2-mediated

443

cytokine production.38, 39 ICOS has also been implicated in the pathogenesis of

444

asthma.40, 41 We have previously shown that Tcm/Tem ICOS activation is higher

445

in AD vs. control children.42 Subsequent data showed acclerated systemic/CLA-

446

ICOS T-cell activation in 0-3y/o AD infants.43 Our present data support ICOS

447

expansion in both healthy and AD development, particularly in CD4+ T-cells.

448

However, positive correlations with age were exclusively seen in AD, and

449

specifically in skin-homing memory subsets. Also, infants and adults with AD

450

have higher CD4+CLA+/CLA- ICOS activation than controls, a difference that is

451

also significant for CD8+ subsets in children. The low CD8+ frequencies in infants,

452

which increase with time,10 may explain the earlier activation of CD4+ subsets.

453

Early involvement of ICOS in AD indicates its possible role in disease induction

454

via either stimulation of T-cell subset polarization, Treg modulation, IgE induction,

455

or ILC2s activation. Furthermore, targeting ICOS/ICOS-ligand in an asthma

456

mouse model altered T-cell differentiation and ameliorated asthma.44 Since AD

457

often precedes asthma,45 CLA- ICOS expansion in AD infants may also be

458

associated with non-cutaneous atopic manifestations. These data suggest the

22 459

potential for ICOS targeting as a preventive or therapeutic approach for AD and

460

atopic associations, though this is speculative and further studies are needed.

461

The chronic T-cell activation MHC class II antigen, HLA-DR,46 increases

462

with age in healthy individuals.47, 48 HLA-DR activation has been shown in chronic

463

adult AD.42 While it is not elevated in AD infants, its activation increases with age.

464

At birth, immune responses are Th2-biased, with low Th1/IFN-γ in both

465

healthy newborns8, 9, 49, 50 and those who eventually develop AD.13 Our data

466

shows that Th1 frequencies increase with age in both AD and control infants.

467

However, and congruent with recent blood data,51 AD subjects display

468

significantly lower IFN-γ frequencies than controls, particularly among CD4+CLA+

469

subsets. Conversely, CLA+Th2 cells are similarly increased across all AD age

470

groups and are significantly higher than controls, even in infants. Systemic/CLA-

471

Th2 cells are significantly higher in AD starting in childhood, which implies

472

systemic Th2 activation with greater chronicity. Consistent with the less dominant

473

role of CD8 suggested in children with early AD42 and low CD8 abundance in

474

infants,10 Tc2 elevations are mostly prominent in adult AD. CLA+ Th1/Th2 ratio

475

correlation with age that is consistently decreased in AD compared to control,

476

and the decreased CLA+/CLA- Th1/Th2 ratio among all AD age groups best

477

reflect the immune imbalance that accompanies AD from birth to adulthood.

478

Circulating Th9 cells have skin-homing predilection.52, 53 IL-9 is elevated in

479

both skin and serum of children with AD, and was also correlated with disease

480

severity.54, 55 While the mechanism by which IL-9 contributes to AD is unknown,

481

IL-9 is linked with mast cell, eosinophil and ILC function and has been thought to

23 482

play a role in AD,56 as well as in other atopic disorders.57-60 Accordingly, IL-9

483

subsets cluster closest to all AD clinical measures

484

(eosinophils/pruritus/SCORAD/EASI/TEWL). Both normal and AD development

485

are characterized by IL-9 increases with age, which drop in adulthood. We show

486

considerably elevated systemic/CLA- T-cells exclusively among the 5-12y/o AD

487

group vs. controls, consistent with early allergy development in childhood with a

488

subsequent decline in adulthood.61, 62 CLA- systemic activation and cytokine

489

polarization with age support the systemic nature of AD and need for systemic

490

therapeutic approaches in moderate-to-severe disease, as well as the

491

association of comorbidities and increased inflammatory and cardiovascular-

492

associated proteins in more chronic AD.63-66

493

Black et al.67 showed strong Th17 skewing early in life. While similar

494

CLA+Th17 frequencies are seen in infants and older individuals regardless of AD,

495

systemic/CLA- Th17 cells are relatively low in infants of both groups and mature

496

with time. IL-17 signatures characterize pediatric AD skin,55 but these changes

497

are not mirrored in the circulation. This discrepancy may be due to increased skin

498

residence of Th17 cells, or by reciprocal peripheral regulation of Th17 and Th2

499

axes.68, 69

500

Skin-homing Th22 is elevated in children, adolescents and adults with AD

501

vs. controls. Congruent with past studies showing that IL-22 is correlated with AD

502

severity,70 we present positive correlations between IL-22-producing CD4+ cells,

503

SCORAD, EASI and pruritus. CD8+ T-cells are major producers of IL-22 in adult

504

AD skin.70 Lower proportions of CD8+ vs. CD4+ in early childhood47, 71 and the

24 505

fact that IL-22 marks AD chronicity42 may explain why skin-homing Th22/Tc22

506

cell frequencies are highest in adolescents and adults. Elevated IL-22 levels,

507

shown to negatively regulate IFN-γ,72 may also contribute to the low Th1

508

frequencies in AD. Systemic/CLA- Th22/Tc22 subset development was similar in

509

AD and controls, potentially suggesting a greater pathogenic relevance of IL-22

510

in AD skin73 and the impaired skin barrier.74 Studies have shown positive

511

correlations and cellular co-production of IL-13 and IL-2222, 75 and of IL-17 and IL-

512

22.27, 76 Indeed, these markers cluster together in the correlation heatmap. IFN-γ

513

clusters with patient age and disease duration, differentiating infants from

514

children and adolescents, and adolescents from AD adults. The association of

515

IFN-γ with disease chronicity agrees with previous chronic adult AD data,

516

suggesting that IFN-γ possibly plays a role in inflammatory disorders chronicity,

517

rather than in disease intiation.26, 42, 77 Expansion of CD8+ memory cells,

518

increases in CLA+IL-22-producing cells, and intensification of ICOS+/HLA-DR+

519

activation with maturity may account for the positive correlations between age,

520

disease duration and severity measures. Increasing severity with age was not

521

seen in a recent study that followed AD infants only between 0-11 months.78

522

TEWL increases with age in AD and correlates with IL-22 (which also increases

523

with age), likely again reflecting the contribution of IL-22 to the barrier impairment

524

in AD.

525

Besides maintaining immune tolerance,79 Tregs influence activation of

526

effector cells.80, 81 Only 5-12y/o children with AD show significantly higher total

527

and skin homing Tregs than controls. This age group is characterized by other

25 528

unique features, including increased skin-homing Tcm/Tem cells, decreased

529

systemic IFN-γ, and increased systemic IL-9 frequencies. Additionally, skin-

530

homing IFN-γ is almost doubled from infancy to childhood AD, although still

531

below age-matched controls. Multiple immunological changes occurring during

532

these years may be involved in AD clearance, or development of non-cutaneous

533

manifestations, commonly occurring during these years.82, 83

534

Profiling AD across ages is imperative for targeted therapeutic

535

development. Unlike psoriasis, in which targeted treatments lead to remarkable

536

responses in most patients, AD responses to targeted therapeutics are much

537

lower.84 This disparity may be attributed to the multi-cytokine activation in AD,

538

despite the shared Th2 activation, vs. the Th17-centered responses in

539

psoriasis.84 Additionally, AD has a highly varied endotype repertoire, with

540

different immune polarizations.3, 85, 86 Despite common features, particularly

541

elevated Th2 expression, AD is endotypically different across ages, and

542

treatments should rather be tailored to the unique age endotype. While one could

543

hypothesize that the immune changes merely reflect developmental phenomena

544

that are age-related, the lack of clear clustering in controls implicates AD as the

545

driver of the distinct, progressive age-related endotypic characteristics rather

546

than age alone. The clustering model, based on the flow cytometry biomarkers

547

splits the entire cohort into 3 separate age clusters only in AD patients.

548

Expectedly, IFN-γ, IL-22, HLA-DR increased chronologically, distinguishing older

549

subjects from infants with AD. Skin-homing Tcm/Tem cells and systemic ICOS

550

activation, both higher in AD infants, separate infants from other groups. This

26 551

model demonstrates that a limited group of blood biomarkers can distinguish

552

among various AD endotypes based on patient age, with a spectrum of age-

553

dependent vs. only ‘infantile’ or ‘adult’ phenotypes. Because our data show that

554

the ‘adult’ or ‘stable’ AD phenotype is only achieved in adulthood, it may be

555

possible to intervene before adulthood and prevent the establishment of the adult

556

AD phenotype.

557

This study has a few limitations. Despite inclusion of different age groups,

558

this study was not longitudinal and thus did not follow the same cohort with time.

559

Additionally, studies in blood do not allow one to measure T-cell subsets in skin,

560

such as tissue-resident memory/Trm T-cells. Furthermore, the study

561

characterized polyclonal T-cell responses, and not antigen-specific responses

562

induced by culprit triggers. Finally, the pathogenicity of immune axes presented

563

here cannot be further dissected without future targeted therapeutic studies to

564

check mechanism.

565

AD was initially considered an early-onset pediatric disease with 75%

566

"outgrowing" their disease by 10y/o.2, 83, 87, 88 More recent studies have

567

established AD as a disorder that often persists into adulthood.89, 90 Comparing

568

the profile of cleared vs. persistent pediatric AD, ideally through longitudinal

569

studies, will better define age-specific characteristics that predict AD clearance.

Figure 8. Unsupervised clustering of AD patients and healthy controls across all

922

principal components of the blood flow cytometry marker frequencies (%) by k-

923

means. In AD, the frequencies of different markers defined three meaningful age-

924

clusters, aligning along a spectrum. While infants (pink ellipse) clustered on the

925

far left, and adults (green ellipse) on the right, children and adolescents (blue

926

ellipse) clustered together between the other age cohorts. The markers that best

927

distinguished between clusters appear in the boxes between two cohorts (colors

928

of markers parallel the colors of the relative age group). Arrows designate

929

elevated frequencies of a given marker among the specific age group. In healthy

930

controls, clusters did not clearly align patients along an age spectrum. CLA,

931

Cutaneous lymphocyte antigen; ICOS, Inducible co-stimulator molecule; Tregs,

932

T-regulatory cells.

Sensitivity analyses for demographic parameters that were significantly different between AD and N within an age-group, with means, medians, and respective Pvalues for the top 10 most significant comparisons. These analyses were done for race-matched infants (A), age-matched children (B), and adolescent AD versus adolescent controls without atopic history (C). Abbreviations AD: Atopic dermatitis; Adol: Adolescent; Child: Children; CLA: Cutaneous lymphocyte antigen; HLADR: Human leukocyte antigen-DR; ICOS: Inducible co-stimulator; IFNγ: Interferon-gamma; IL: Interleukin; N: Normal; Tcm: Central memory T; Tem: Effector memory T; Treg: Regulatory T

Supplementary Materials and Methods

Isolation of Peripheral blood mononuclear cells and multiparameter flow

3

cytometry blood analyses

4

Peripheral blood mononuclear cells (PBMCs) were obtained by gradient

5

centrifugation with Ficoll-Paque Plus (Amersham Biosciences, Pittsburgh, PA).

6

The blood was laid under the Ficoll gradient; after spinning, the PBMCs were

7

collected at the interface between the plasma and the Ficoll gradient and washed

8

with PBS before staining for flow cytometry analysis. For T-cell surface staining,

9

PBMCs were washed and incubated for 30 minutes in ice with fluorochrome-

10

conjugated monoclonal antibodies (mAbs) to cell surface molecules (CD3-Pe AF

11

610, CD8-V-500, CD4-Qdot800, CD45RO-PeCy7, CLA-FITC, ICOS-

12

PerCpCy5.5, CCR7-Alexa Fluor 700, HLA-DR-APC-H7, CCR4-BV 421, CD25-

13

PE, CD127-BV 650, Live/dead-Blue Dye). Then, the cells were fixed in ice with

14

4% paraformaldehyde (BD Biosciences, San Jose, CA) for 20 minutes. For

15

intracellular cytokine staining, whole blood was activated with 25 ng/mL of

16

phorbol 12-myristate 13-acetate (PMA) and 2 µg/mL of ionomycin in the

17

presence of 10 µg/mL brefeldin A (protein transporter inhibitor) for 4 hours at

18

37°C. All reagents were purchased from Sigma Aldric h (St. Louis, MO). Non-

19

activated controls were only treated with brefeldin A. After this incubation, EDTA

20

(2 mM; Invitrogen, Grand Island, NY) was added for 15 minutes at room

21

temperature (RT) to stop activation. The blood was then incubated with FACS

22

lysing solution for 10 minutes at RT and washed with PBS twice. Then, the cells

23

were incubated for 20 minutes with fluorochrome-conjugated mAbs to cell

2 24

surface molecules (CD3-Pe AF 610, CD4-Qdot800, CLA-FITC). Subsequently,

25

the cells were permeabilized (Perm/Wash; BD Biosciences, San Jose, CA) and

26

incubated for 20 min with fluorochrome conjugated mAbs (IL-13-PerCpCy5.5, IL-

27

22-PeCy7, IL-9-Pe, IFN-γ- Alexa Fluor 700 and IL-17-APC efluor 780) in 5%

28

mouse serum (eBioscience, San Diego, CA). All incubations for cell surface and

29

intracellular staining were done at RT. Appropriate FMO-isotype controls were

30

used. Following incubations, cells were washed and subsequently acquired with

31

a BD LSR II flow cytometer (BD Biosciences) and analyzed by flow-Jo software

32

(Treestar, Ashland, OR).
