WebJun 20, 2002 · Complementary approaches with purified molecules or transfected cytolytic effector cells have suggested that both, granzyme A (gzmA) and granzyme B (gzmB), similarly contribute to CTL-mediatedand perforin (perf)-dependent apoptotic nuclear damage (DNA fragmentation) in target cells. Studies employing gzmA or gzmB single-knockout … WebEven in these conditions, Bcl11b-deficient CTLs presented reduced Ag-specific killing activity, demonstrating that the reduced killing activity is not only a result of reduced numbers of CTLs. Thus, the reason for poor cytolytic activity could be caused by a reduction in the cytolytic effector molecules, perforin, and granzyme B.
