Attenuation of AMPK signaling by ROQUIN promotes T follicular helper cell formation.

abstract：:Aging is an intricate phenomenon associated with the gradual loss of physiological functions, and both nutrient sensing and proteostasis control lifespan. Although multiple approaches have facilitated the identification of candidate genes that govern longevity, the molecular mechanisms that link aging pathways are sti...
