The CD4/CD8 T cell ratio is a good indicator of the proper functioning of the immune system. T cells are a category of cells that are part of the lymphoid lineage. To learn more about the various cells of the lymphoid lineage, read our new infodump! Click on the link above

Ethnopharmacological relevance: The efficacy of immunotherapy for hepatocellular carcinoma (HCC) is often limited by an immunosuppressive tumor microenvironment (TME), largely driven by tumor metabolic reprogramming (the Warburg effect) that impairs CD8+ T cells. Targeting this metabolism to restore immunity is a promising strategy. Bie-Jia-Jian Pill (BJJP), a traditional formula for “softening…

Bispecific T cell engagers (TCEs) often exhibit limited efficacy in solid tumors, in part due to immunosuppressive cues in the tumor microenvironment and low expression of targetable tumor antigens. Therapeutic strategies to improve TCE target sensitivity and enhance T cell effector functions therefore have significant translational potential. Here, we engineered TCEs that induce T cell…

Neutrophil-specific targeting of STAT3 impairs tumor progression via the expansion of cytotoxic CD8+ T cells Summary Targeting STAT3 specifically in neutrophils, a type of white blood cell, significantly hinders tumor progression, according to this research. The mechanism behind this involves a boosted presence and activity of cytotoxic CD8+ T cells, immune cells crucial for directly killing…

The prostacyclin receptor PTGIR is a NRF2-dependent regulator of CD8+ T cell exhaustion Summary Research indicates that the prostacyclin receptor, PTGIR, plays a crucial role in regulating CD8+ T cell exhaustion, a state of dysfunction that hinders effective immune responses against chronic infections and cancer. The study highlights that PTGIR expression in CD8+ T cells is dependent on NRF2, a…
