Although it is well known that in various T cell-mediated skin diseases T cells migrate preferentially to epidermis, no direct evidence has been presented in which molecules on T cells are important in directing T cell traffic to epidermis. We have previously established CD4+ autoreactive cloned T cells with a special tropism for epidermis in vitro as well as in vivo. Antibody inhibition studies demonstrated that only anti-lymphocyte function associated Ag 1 (anti-LFA-1) mAb completely inhibited the in vitro migration of the T cells toward the epidermis, whereas mAb against other T cell surface molecules had little or no effect. Monovalent F(ab) fragment of the anti-LFA-1 mAb, although less efficient, also inhibited the T cell migration. The apparent dependency of the inhibition on the anti-alpha-chain mAb suggested a major role for the alpha-chain of LFA-1 in T cell migration to epidermis. The relevance of an LFA-1-dependent mechanism to the epidermotropic migration of T cells was further strengthened by the findings that the T cell migration to epidermis was inhibited by divalent cation depletion, cytochalasin B, and low temperature. These findings indicate that the LFA-1 molecule, which is thought to be primarily involved in cell-to-cell adhesions, also plays an important role in directing T cell migration to epidermis.
