After short term culture, LC up-regalate la anttgen and casthmuktory molecules as well as increase antigen presenting cell function. We have demonstrated in viva that murine LC show the phenotypk smd functional activation after hnpten appliiation similar to that noted in in vitro-activated LC. To elucidate the mechanism of the up-regulation of costimulatory molecules on murine LC in vitro and in viva, we examined the effects of monoclonnl antibodies(mAb1 tu!aiast GM-CSF. TNFa and IL-lp on the up-regulation of ICAM: a&i B? by cultured iC, and also examined the effects of intradermsl injection of GM-CSF, TNFa and IL-lb 00 the costhnuktory mokcuk expression by murine LC in viva When we added anti-GM-CSF or anti-TNFa mAb to the culture of epidcrmsl cells, the up-regulation o( 87 on LC was inhibited, while the increased expression of lo antigen remained unchanged. The addition of snti.IL.la mAb to the culture did not inhibit the upregulation of costimulntcry molecules or la antigen. In contrast, when we injected intrsdermaliy IL-lp or TNFa, LC up-regukted ICAM-I and la antigen, but not 87 significantly. The injection of GM-CSF could not up-regulate ICAM-I, 87 or IP antigen.

HLA-B13 IS A MELANOGENESIS-RELATED MOLECULE
The amount of filaggtin in the non-lesional
skin of atopic dermatitis
patients is decreased.
M. MUTO, Y. HAMAMOTO,S. MOGAMI, T. SHIMIZU and C. ASAGAMI, Departmentof Dermatology,Yamaguchi UniversitySchool of Medicine, Ube, Japan It has not been clear whether HLA antigens are associated with melanoaenesis. In order to elucidate involvementof HLA aenes relevant to melanin formation,we performed an HLA populationsurvey, by using peripheralblood lymphocyte obtained from 28 unrelated Jaoanese oatients with melanoma. 10 patients with vitiligo and'120 nohl healthy controls.The results showed that there was a strong association between melanoma and HLA-B13 (25.0% (7/28) jn patients vs 2.5% (3/120) in controls, relative risk = 13.0, p < 0.005). Moreover,the frequencyof HLA-613 antigen was moderately increased in vitiliqo (2/10 = 20.0% vs 3/120 = 2.5%, relative risk = 9.8, p < 0.05). These observations lead to an idea activity
that HLA-B13 controlling
gene is related the melanogenesis
with of
tyrosinase the melanocytes.
As the skin of alopic dermatitis patients is usually dry and scaly, such emollient factors as amino ackts and urocanic acid could be decreased in the stratum comaurn of these patients. The pracursor protein of these emolliinl factors is filaggrin tiich is synthesized in the stratum granulosum. The purpose of this study is to determine the amount of filaggrin synthesized in the non-lesional skin of atopic dermatitis patients. We have determined the amount of filaggrin by two mathods; the one is immunohislochemical method and the another is fmmuno-biochemical method: the biopsiad spedmen with a 3 mm punch was lyophilirsd. extracted. subjwtad lo SDS-PAGE and immuno blotted. The density of a potein band was measured and the net amount of protein from the densitomaterical number was determined according lo the previously-determined standard curve. [Ftesufts] lmmunohi&c&amimlly, the amount of fflaggrin was remarkably decreased in lhs non-tasiinal skin of atopic dermalftis. Its net anwunt in 3 mm non-lesional skin of the atopic dermaliiis patients was around 3.1 ug. but in contrast, around 6.5ug in the normal control. [Conclusion] Fibggrin synthesis was decreased in the non-lesional skin of alopic dsmlat&palisnts.
