In vivo induction of Ia antigens on rat keratinocytes by gamma-interferon

Recombinant rat IFN-gamma was found to induce Ia antigen expression on rat keratinocytes in vivo. Strong expression of Ia antigen on keratinocytes of rat ears was produced after intradermal injections of 10,000 U IFN-gamma once daily on 3 successive days. The expression was still pronounced 2 days after the last injection, but had disappeared 4 days later.
