TNF production by HLA-B60 HY CTL after stimulation with HeLa transfected with UTY and HLA-B60 cDNA.
HeLa cells were cotransfected with indicated Y-specific cDNA and HLA-B60 cDNA. Forty-eight hours after transfection, HLA-B60 HY CTL was added. Culture supernatants were harvested 1 day later and tested for TNF production.
