  Chronic exposure to trauma and violence can promote aggressive behavior. Oxytocin and variants in the oxytocin receptor (OXTR) gene may play a role in the etiology of proactive, that is, goal‐oriented instrumental aggression, or reactive aggression, which typically occurs in response to emotionally triggering situations. The current study builds on previous findings that experienced and witnessed trauma in childhood predicts higher levels of appe…

  OBJECTIVE: Inadequate immunoregulation and elevated inflammation may be risk factors for posttraumatic stress disorder (PTSD), and microbial inputs are important determinants of immunoregulation; however, the association between the gut microbiota and PTSD is unknown. This study investigated the gut microbiome in a South African sample of PTSD-affected individuals and trauma-exposed (TE) controls to identify potential differences in microbial div…
