title: Expression of vitiligo antigen on a revertant line of hamster melanoma cells.
abstract: Our laboratory has recently reported that over 80% of patients with common vitiligo have circulating antibodies to cell-surface antigens on normal human melanocytes. The slow growth rate of these cells limits the assays that can be performed for antibody detection. We now have found that the antigens defined by vitiligo sera on melanocytes are also expressed on FF cells, a revertant line of hamster melanoma cells. These antigens can be detected both by indirect immunofluorescence and specific immunoprecipitation assays. The presence of "vitiligo" antigens on hamster FF cells will aid further study of the abnormal immune response in vitiligo.
