title: The effect of gamma-interferon on HLA class II antigen expression on isolated human nasal chondrocytes.
abstract: HLA class II antigens play an important role in the immunological response. In this study, we report on HLA class II antigen expression in vitro by human nasal cartilage cells as detected with an immunoperoxidase staining and immunofluorescence flow cytometric analysis using monoclonal antibodies. Their expression was induced during a 7-day incubation period with gamma-interferon. These findings suggest that a possible mode of action of the preservation methods of cartilage allografts for inducing a prolonged acceptance time is based on the prevention of HLA class II antigen expression by the cartilage cells.
