Abstract

We investigated the expression of Ly-6.A2 on isolated murine epidermal cells by flow cytometry. Ly-6.A2 was expressed on 61% of keratinocytes and 6% of dendritic epidermal T cells of C57BL mice. Phosphatidylinositol-specific phospholipase C removed Ly-6.A2, indicating that the antigen is anchored to the keratinocyte membrane via a glycosyl-phosphatidylinositol anchor similar to its attachment to the membrane of lymphocytes. Induction of dermatitis by topical application of PMA increased the expression of Ly-6.A2 of TCRγδ+ dendritic epidermal T cells and did not change its expression on keratinocytes. The increased expression of Ly-6.A2 on dendritic epidermal T cells was transient and reached a peak at 4 days after application of PMA, when 55% of the cells were positive.
