Maternal Western-Style Diet Reduces Social Engagement and Increases Idiosyncratic Behavior in Japanese Macaque Offspring

Evidence points to an association between maternal obesity and risk of early-emerging neurodevelopmental disorders in offspring, yet few preclinical studies have tested for associations between maternal Western-style diet (mWSD) and offspring behavior. Using Japanese macaques, researchers found that mWSD offspring exhibited less proximity to peers and initiated fewer affiliative social behaviors. These outcomes appear to be mediated by increased maternal interleukin-12 during the third trimester of pregnancy. Additionally, mWSD offspring displayed increased idiosyncratic behavior, which was related to alterations in maternal adiposity and leptin. These findings suggest specific prevention and intervention targets for early-emerging neurodevelopmental disorder in humans. Supported by ORIP (P51OD011092), NIMH, and NICHD.
X Chromosome Agents of Sexual Differentiation

Many diseases affect one sex disproportionately. A major goal of biomedical research is to understand which sex-biasing factors influence disease severity and to develop therapeutic strategies to target these factors. Two groups of such agents are sex chromosome genes and gonadal hormones. Researchers use the “four core genotypes” model to enable comparisons among animals with different sex chromosomes but the same type of sex hormones, which allows investigators to distinguish disease mechanisms influenced by the sex chromosomes.
