WebJul 30, 2024 · Both treatment regimens increased transcripts associated with cytolytic effector function and decreased transcripts associated with naive T cells. These responses were further evaluated at the protein level and extended to a total of 53 patients with various cancer types. Unexpectedly, the induction of CD8+ T cell responses associated with ... WebDec 14, 2024 · Effector functions within the T cell compartment are critical for shaping immune responses in numerous disease states. CD4 + T cell effector function is thought to be centered around cytokine production, whereas direct cytotoxic activity against target cells resides within the CD8 + T cell compartment. However, these boundaries can be plastic, …

WebApr 4, 2024 · Next, we examined the cytolytic activity of each T-cell population using a luciferase-based cytotox-icity assay. Effector T cells were plated in the presence of CD123 + (MOLM13.ffLUC, MV-4-11.ffLUC and Kg1a.ffLUC) or CD123 – targets (K562.ffLUC) at a 1:1 effector to target (E:T) ratio. 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).
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.
