Identification of a specific HLA DR2 Ia molecule as a restriction element for measles virus-specific HLA class II-restricted cytotoxic T cell clones


By using a panel of HLA-D-defined subtypes of HLA-DR2 HCL with known beta chain structural variabilities, we have demonstrated that HLA-DR2, OKT4+ cytotoxic T lymphocyte (CTL) clones specific for measles virus are apparently restricted to a distinct DR beta chain. The presence of this DR beta 2 molecule correlated precisely with the susceptibility of… (More)
