Chromatin remodeling factor BAF155 coordinates oligodendroglial-neuronal communications linked to regional myelination and autism-like behavioral deficits in mice.

ABSTRACT: Autism spectrum disorders (ASD) are neurodevelopmental disorders associated with synaptic deficits. Oligodendrocyte precursor cells (OPCs) are the only type of glial cells that establish direct synaptic connections with neurons within the central nervous system (CNS). However, the mechanism that results in the delicate construction of OPC-neuron synaptic connections remain poorly understood. Here we show in a mouse model that BAF155, a chromatin remodeling factor, is highly expressed in committed OPCs. BAF155 influences the OPC differentiation and myelination by coordinating the expression of multiple synapse-related genes that mediate OPC-neuron synaptic communication. The varying chromatin regulatory roles of BAF155 across brain regions give rise to local myelin deficits, contributing to
