Here we show that intratumoral T cells undergo translatome remodeling, transitioning into a hypertranslational state as they acquire dysfunctional traits. The RNA-binding protein LARP4 is a translation regulator that drives hypertranslation and dysfunction by selectively enhancing the translation of nuclear-encoded oxidative phosphorylation (OXPHOS) mRNAs in exhausted T cells, disrupting OXPHOS subunit balance and causing mitochondrial dysfunction. Knockout of <i>Larp4</i> in tumor-specific CD8<sup>+</sup> T cells reduces hypertranslation, restores mitochondrial function, mitigates exhaustion and enhances effector persistence, resulting in enhanced anti-tumor responses. Additionally, <i>LARP4</i> knockdown in chimeric antigen receptor T cells prevents terminal exhaustion and improves the response to liquid and solid tumors.

The gut microbiome profoundly influences T cell biology by producing a diverse repertoire of small molecules that are sensed by host cells.

Recent studies have uncovered microbially derived molecules, including short-chain fatty acids, secondary bile acids and tryptophan metabolites, as potent regulators of T cell function. However, the full scope of microbial metabolite–T cell interactions remains largely unexplored. This Review presents a mechanistic framework linking gut microbial metabolites to discrete stages of T cell fate and function.

We show that, in dense environments where even the largest pores preclude free passage, leukocytes position their nucleus behind the centrosome and organelles. The local compression imposed on the cell body by its surroundings triggers assembly of a central F-actin pool, located between cell front and nucleus. Central actin pushes outward to transiently dilate a path for organelles and nucleus. Pools of central and front actin are tightly coupled and experimental depletion of the central pool enhances actin accumulation and protrusion formation at the cell front. Although this shifted balance speeds up cells in permissive environments, migration in restrictive environments is impaired, as the unleashed leading edge dissociates from the trapped cell body.
