Cytolytic response of human T cells against allogeneic small cell lung carcinoma treated with interferon gamma.
Human lymphocytes stimulated in vitro by allogeneic small cell lung carcinoma cell lines did not show any significant cytolytic activity against the stimulator tumor cells. However, a high level of lysis was observed when both stimulator and target small cell lung carcinoma cells were pretreated with interferon gamma, which increased considerably the expression of major histocompatibility class I molecules by these cells. The demonstration that small cell lung carcinoma cells can be lysed by cytolytic T lymphocytes, suggests that it will be feasible to study the autologous T cell response of patients against this tumor.
