Abstract Dysfunction of invariant natural killer T (iNKT) cells in tumor microenvironment hinders their anti-tumor efficacy, and the underlying mechanisms remain unclear. Here we report that iNKT increase lipid biosynthesis after activation, is promoted by PPARγ PLZF synergically through enhancing transcription Srebf1 . Among those lipids, cholesterol required for optimal IFN-γ production from cells. Lactic acid reduces expression intratumoral consequently diminishes synthesis production....

ABSTRACT Aging increases the susceptibility to metabolic dysfunction–associated steatotic liver disease (MASLD). Liver sinusoidal endothelial cells (LSECs) help in maintaining hepatic homeostasis, but contribution of age‐associated LSECs dysfunction MASLD is not clear. The aim this study was investigate effect aging‐associated on MASLD. Free fatty acid–treated AML12 were co‐cultured with young and etoposide‐induced senescent TSEC evaluate senescence‐associated effects lipid accumulation...
