TNF production by HLA-B60 HY CTL after stimulation with HeLa transfected with UTY cDNA.
HeLa cells were transfected with UTY or UTYdeletion mutants cDNA and HLA-B60 cDNA (▧), or without 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.
