Autogenous Control
both the specific and the memory component of the immune response to provide long-term protection from a specific disease. The immune response is normally directed against external agents but a category of diseases, autoimmune diseases, arise as a result of immune reactivity to the body's own components. These autoimmune responses are both specific and have memory. When this immune reactivity is directed against a discrete target organ such as the insulin-secreting b cells of the pancreas, this is termed an organ-specific autoimmune disease. If the reactivity is directed against a more generalized target such as DNA this is called a nonorgan-specific autoimmune disease. The development of autoimmune disease is normally controlled by many genes, some of which may govern the innate and some the adaptive immune response. See also: Immunoglobulin Gene Superfamily

An autonomous controlling element is an active transposon (in maize) demonstrating the ability to transpose (cf. nonautonomous controlling element)

Autogenous control is the process by which a gene product either inhibits (negative autogenous control) or activates (positive autogenous control) expression of the gene coding for it.
The immune system provides one of the body's most important defense mechanisms against infection. The immune system can be subdivided into two branches, innate and adaptive. Key features of the adaptive immune response are that it is specific and that it has a memory component. Vaccination utilizes
Autoregulation is a term used for situations in which a gene or gene product regulates its own activity, either positively or negatively. Most cases of autoregulation
