Social rank 'linked to immunity'
http://www.bbc.co.uk/news/science-environment-17663133A 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 team also showed that the monkey's immunity changed when social rank was altered.
