Cancer immunotherapy utilizing cytotoxic T lymphocytes (CTLs) has demonstrated significant promise in clinical applications, but cancer immunosuppressive mechanisms hamper further progress in T cell immunotherapy. Here we show a correlation between cancer cell mitochondria content and their resis...
CD8+ T cells detect and kill virally infected or cancerous cells. When activated from their naïve state, T cells undergo a complex transition, including major metabolic reprogramming. Detailed resolution of metabolic dynamics of a wide range of metabolites is needed to advance the field of immuno...
To elucidate the function of oxidative phosphorylation (OxPhos) during B-cell differentiation we employ CD23Cre-driven expression of the dominant-negative K320E mutant of the mitochondrial helicase Twinkle (DNT). DNT-expression depletes mitochondrial DNA during B cell maturation, reduces the abun...
Paraoxonase-1 (PON1) is specifically expressed in the liver and has crucial effects on various liver diseases. The functions and mechanisms underlying of PON1 in hepatocellular carcinoma (HCC) remain obscure. Here, we show that PON1 acts as a metabolic regulator to mitigate regulatory T (Treg) ce...
In cancer, metabolic changes and uncontrolled tumor growth alter nutrient availability, impacting antitumor immune responses. Regulatory T (Treg) cells are a subset of T cells with immunosuppressive properties that has been found to additionally possess the ability to control tissue homeostasis a...
