Journal ArticleDOI
Social environment is associated with gene regulatory variation in the rhesus macaque immune system
Jenny Tung,Luis B. Barreiro,Luis B. Barreiro,Zachary P. Johnson,Kasper D. Hansen,Vasiliki Michopoulos,Donna J. Toufexis,Donna J. Toufexis,Katelyn Michelini,Mark E. Wilson,Yoav Gilad +10 more
TL;DR: The results illuminate the importance of the molecular response to social conditions, particularly in the immune system, and demonstrate a key role for gene regulation in linking the social environment to individual physiology.
Journal ArticleDOI
Social status alters immune regulation and response to infection in macaques
Noah Snyder-Mackler,Joaquín Sanz,Joaquín Sanz,Jordan N. Kohn,Jessica F. Brinkworth,Jessica F. Brinkworth,Shauna Morrow,Amanda O. Shaver,Jean-Christophe Grenier,Roger Pique-Regi,Zachary P. Johnson,Zachary P. Johnson,Mark E. Wilson,Mark E. Wilson,Luis B. Barreiro,Luis B. Barreiro,Jenny Tung +16 more
TL;DR: Genomics is combined with social status manipulation in female rhesus macaques to investigate how status alters immune function, and causal but largely plastic social status effects on immune cell proportions, cell type–specific gene expression levels, and the gene expression response to immune challenge are demonstrated.
Journal ArticleDOI
Dominance rank causally affects personality and glucocorticoid regulation in female rhesus macaques
Jordan N. Kohn,Noah Snyder-Mackler,Luis B. Barreiro,Zachary P. Johnson,Zachary P. Johnson,Jenny Tung,Mark E. Wilson,Mark E. Wilson +7 more
TL;DR: These findings indicate that social status causally affects both behavioral tendencies and glucocorticoid regulation, and that some behavioral tendencies also independently affect cortisol levels, beyond the effects of rank, and highlight the importance of considering personality and social status together when investigating their effects on HPA axis function.
