# s-pnei: how social status alters immune function in macaques

<< Americans differ in life expectancy by more than a decade. Glaring health inequalities across the socioeconomic spectrum are often attributed to access to medical care and differences in habits such as smoking, exercise and diet. But a new study in rhesus monkeys shows that the chronic stress of life at the bottom can alter the immune system even in the absence of other risk factors. The research confirms previous animal studies suggesting that social status affects the way genes turn on and off within immune cells >>

AA << combined genomics with a social status manipulation in female rhesus macaques to investigate how status alters immune function >>

AA << identify specific transcription factor signaling pathways that explain these differences, including low-status–associated polarization of the Toll-like receptor 4 signaling pathway toward a proinflammatory response >>
