Activation of adenosine monophosphate-activated protein kinase (AMPK) plays a central role in allowing cells to adapt to nutrient deprivation in vitro. This link between AMPK activity and nutritional status has raised the possibility that AMPK plays a role in the metabolic adaptation to acute and chronic nutritional stress. However, the effects of(More)
Despite the central role of adenosine monophosphate-activated protein kinase (AMPK) in the cellular stress response, it is unknown whether age-related changes in AMPK activity play a role in the diminished stress tolerance that is characteristic of aging. To address this question, we determined in the mouse liver how normal aging affects 1) basal AMPK(More)
Natural killer (NK) cells require interaction of inhibitory surface receptors with human leukocyte antigen (HLA) ligands during development to acquire functional competence in a process termed “licensing.” The quantity of HLA required for this process is unknown. Two polymorphisms affecting HLA-C surface expression (rs9264942 and rs67384697) have recently(More)
