Social Rank Linked to Immunity

Social Rank Linked to Immunity

A study of rhesus macaque monkeys may have solved a long-standing puzzle on a link between social rank and health. A study of 10 social groups of macaque females showed that the activity level of an individual’s immune genes was an accurate predictor of her social rank.

In a paper in Proceedings of the National Academy of Sciences, the research team also showed that the monkey’s immunity changed when social rank was altered. The work suggests that status drives immune health, rather than vice-versa. A great many studies have shown associations in both humans and non-human primates between social environment and biological markers of health.
