Abstract Suppressed NMDA receptor (NMDAR) function contributes to multiple brain disorders, including schizophrenia, autism spectrum disorder (ASD), and NMDAR encephalitis. Previous attempts to restore NMDAR activity by increasing ambient glycine, a critical co-agonist, through GlyT1 inhibition have yielded mixed outcomes, partly due to GlyT1’s extensive expression in essential brainstem regions.

Abstract CHD8 is a chromatin remodeler implicated in autism spectrum disorders (ASD) and multiple neurodevelopmental disorders, yet heterozygous Chd8-mutant mouse lines often exhibit only mild ASD-related phenotypes, leaving its role unclear. Because a complete knockout of Chd8 causes embryonic lethality, we generated viable homozygous Chd8-mutant mice carrying the human CHD8-Asn2373LysfsX2 mutation using a hybrid (C57BL6/J × 129/Sv) genetic background.

Abstract Autism spectrum disorder is characterized by early postnatal symptoms, although little is known about the mechanistic deviations that produce them and whether correcting them has long-lasting preventive effects on adult-stage deficits. ARID1B, a chromatin remodeler implicated in neurodevelopmental disorders, including autism spectrum disorder, exhibits strong embryonic- and early postnatal-stage expression.
