WebApr 14, 2024 · CD4+ T cells are typically considered as ‘helper’ or ‘regulatory’ populations that support and orchestrate the responses of other lymphocytes. However, they can also develop potent granzyme (Gzm)-mediated cytotoxic activity and CD4+ cytotoxic T cells (CTLs) have been amply documented both in humans and in mice, particularly in the … WebJun 8, 2024 · Cancer cell death enhances the elimination of the tumor stroma through the release of tumor antigens that sensitize stromal cells for antigen-specific CTL killing (38–40). Tumor necrosis factor (TNF), Fas ligand (FasL), and IFN-γ expression by CTLs—together with the expression of their respective receptors TNFR, Fas, and IFN-γR …

WebJan 10, 2024 · Engagement of the adenosine 2A receptor and TIM3 reduced tumor cell killing in spheroids, impaired CTL cytoskeletal polarization ex vivo and in vitro and inhibited CTL infiltration into tumors and spheroids. With this role in CTL killing, blocking A 2A R and TIM3 may complement therapies that enhance T cell priming, e.g. anti-PD-1 and anti … WebTransfection of CTLs with NKG7 mRNA improved tumor-cell killing ability and increased response to anti-PD-1 or anti-PD-L1 in vitro. NKG7 mRNA therapy also improved the response of antigen-specific CTLs in mice in an in vivo model of adoptive T cell therapy.
