| Research Abstract |
AID, a DNA mutagenic enzyme, was expressed in inflammatory skin disorders, including lichen planus, lichen sclerosis et atrophicus and DLE. The AID was not expressed in human keratinocyte cell line, however, addition of TNF-a, a inflammatory cytokine, induced the ectopic expression of AID in this cell line. These data suggested that sustained inflammation in skin yielded the ectopic expression of AID in keratinocytes. As a result of aberrant expression of AID, the enzyme induces DNA mutation and skin carcinogenesis.
