Cytolytic effector
WebThe importance of oxygen sensing in regulating effector T cell function is increasingly recognized. The HIF1 signaling pathway is a crucial regulator of T cell differentiation and controls the production of glucose transporters, glycolytic enzymes, chemokine receptors, adhesion molecules, and the cytolytic effector molecule perforin (21, 49). WebNov 11, 2013 · The redirected cytolytic activity, however, was nearly the same. Although the study confirms previous observations that increase in affinity does not necessarily improve all T-cell effector functions, the comparison of the CARs is alleviated in that two binding domains targeting different epitopes, although in the same domain of the targeted ...

In contrast, CD8 + T cells, through the redundant expression of Eomes and T-bet, are fated to develop into cytolytic effector cells that produce IFN-γ and express granzyme B and perforin. 11,15 It is not known if induction of IL-17 production in this cytolytic lineage …
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. 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 …
