Low-dose mixtures of dietary nutrients ameliorate behavioral deficits in multiple mouse models of autism.

ABSTRACT: Autism spectrum disorder (ASD) is a group of heterogeneous, behaviorally defined neurodevelopmental conditions influenced by both genetic and environmental factors. Here, we show that supplementation of multiple low-dose nutrients-an important environmental factor contributing to ASD-can modulate synaptic proteomes, reconfigure neural ensembles, and improve social behaviors in mice. First, we used Tbr1+/- mice, a well-established model of ASD, to investigate the effect of nutrient cocktails containing zinc, branched-chain amino acids (BCAA), and serine, all of which are known to regulate synapse formation and activity. Supplementation of nutrient cocktails for 7 days altered total proteomes by increasing synapse-related proteins. Our results further reveal that Tbr1 haploinsufficiency prom
