Enduring Autism-like Phenotypes and Deregulated Hypothalamic Prosocial Peptides After Early-Life Exposure to Indoor Flame Retardants in Male C57BL/6 Mice.

ABSTRACT:

Background

Polybrominated diphenyl ethers (PBDEs) are neuroendocrine disrupting chemicals that produce adverse neurodevelopmental effects. PBDEs have been implicated as risk factors for autism spectrum disorder (ASD), which is characterized by abnormal psychosocial functioning and is commonly accompanied by co-morbidities such as cognitive and attentional deficits. Here, we used a mouse model with translationally relevant exposure to establish direct causal evidence that maternal transfer of a commercial mixture of PBDEs, DE-71, produces ASD-relevant behavioral and neurochemical deficits in male offspring.

Methods

C57Bl6/N mouse dams were exposed to a commercial PBDE mixture, DE-71, via oral administration of 0 (vehicle control, VEH/CON), 0.1 (L-DE-71), or 0.4 (H-DE-71) mg/k
