- Resveratrol stimulates the metabolic reprogramming of human CD4+ T cells to enhance effector function
Resveratrol alters human T cell responsiveness to antigens, coupling a replication stress response to metabolic reprogramming.
- The matricellular protein TSP1 promotes human and mouse endothelial cell senescence through CD47 and Nox1
Endothelial cell senescence induced by TSP1 and its receptor CD47 is mediated by Nox1-dependent oxidative stress.
- Olfactory experience primes the heat shock transcription factor HSF-1 to enhance the expression of molecular chaperones in C. elegans
The odor of a pathogenic bacterium primes nematodes to respond to the pathogen when they eventually encounter it.

The articles highlighted this week focus on signaling events that control appetite and weight; the effects of Hippo signaling on cell function during cardiac repair; a mechanism that drives cancer drug addiction; inactivation of a kinase complex by structural rearrangement; and the mechanism by which a noncoding viral RNA inhibits host cell apoptosis.
About The Cover

Online Cover This week features a Research Article that examined the effect of resveratrol, a polyphenolic compound found in grapes, on human CD4+ T cell function. When used at low doses, resveratrol reprogrammed the metabolism of the T cells, making them more responsive to antigen and enhancing their production of an inflammatory cytokine, suggesting that the therapeutic use of resveratrol should be carefully assessed.
