Abstract:ObjectiveTo investigate the activities of protein kinase C (PKC) and tyrosine protein kinase (TPK) in the activated and proliferating T cells and the induction of apoptosis of the hepatoma cells. MethodsHealthy human PBLs were co-stimulated by anti-CD28 and anti-CD80 (B7.1) McAb and acted on the hepatoma cells (BEL-7402). ResultsThe activities of PKC and TPK were significantly higher in the activated T cells than those in the control cells, and were positively related to apoptosis of hepatoma cells. ConclusionPKC and TPK play important role on the signal transduction in the activated and proliferating T cells and the induction of apoptosis of hepatoma cells.
