[Mechanism of action and therapeutic use of cyclosporin A. Experimental and clinical experiences in dermatology].

The clinical application of cyclosporine A caused many success in transplantation surgery as well as in the treatment of (auto-) immune disorders. The biological highly active substance differs from conventional immunosuppressive drugs (i.e. steroids, azathioprine) by it's selective action on T-lymphocytes. However, current experimental findings indicate a direct influence on epidermal keratinocytes, too. First therapeutical experiences, concerning systemic and topical application in different skin diseases are summarized.
