Differential effect of griseofulvin on interferon-γ-induced HLA-DR and intercellular adhesion molecule-1 expression of human keratinocytes

Abstract

Interferon-gamma (IFN-gamma) induces major histocompatibility complex (MHC) class II antigen and intercellular adhesion molecule-1 (ICAM-1) expression on human epidermal keratinocytes. Griseofulvin, an extensively used antifungal agent, has been used effectively in the treatment of lichen planus, in which keratinocytes express both HLA-DR and ICAM-1 antigens. In this study, we investigated the effect of griseofulvin on IFN-gamma-induced MHC class II antigen and ICAM-1 expression of keratinocytes, and demonstrated that griseofulvin decreased IFN-gamma-induced HLA-DR but not ICAM-1 expression.
