Inhibition of the proliferation of cytotoxic tyrosinase-specific CD8+ T cells by IL-10–treated DC. Tyrosinase-specific, cytotoxic CD8+ T cells were cultured with the specific tyrosinase peptide, either in combination with HLA.A2+ DC pretreated with IL-10 or untreated. In control experiments, the unspecific peptide MART-1 was added to the culture. Proliferation was measured by incorporation of [3H] TdR after 3 days of culture. The results represent one of three experiments.
