SpletThe proportions of baseline naïve and memory T-cells were measured by flow cytometry and correlated with OS, with an emphasis on PD-1 expression. High frequencies (>13%) of CD8 effector-memory type 1 (EM1) T-cells at baseline correlated with longer OS (p = 0.029) and higher clinical response rates (p = 0.01).

Surprisingly, however, such variants are less effective than wild-type IL-2-Fc in mediating tumour rejection.

We next examined the role of IL-2 signaling in development of the SLEC and MPEC … Splet13. jul. 2001 · After the pathogen is destroyed, most effector T cells are eliminated—thereby preserving the primary T cell repertoire—but some cells survive and form long-lived memory cells. During each stage of this process, the life or death fate of T cells is strictly regulated. Immune responses leading to rejection of infectious agents usually ...

SpletIt was also found that massively proliferated T cells are more likely to generate short-lived effector cells, while minimally proliferated T cells would form more long-lived cells. [11] … SpletHowever, blockade of TGF-β signaling on effector CD8 + T cells caused an increase in their total number, which was a result of reduced apoptosis of short-lived effector cells during clonal expansion. We further demonstrate that TGF-β provides an extrinsic signal to further downregulate Bcl-2 expression in effector cells and selectively ...
