Key Points

To explore how oligodendrocyte precursor cells (OPCs) influence visual development through phagocytosis and CHD8 regulation.
Examined the role of OPCs in synapse clearance during visual development around eye opening.
Analyzed gene expression changes related to phagocytosis driven by CHD8.
Investigated the dysregulation of the phagocytic pathway in the context of autism.
Phagocytosis by OPCs was identified as essential for synapse refinement during visual development.
CHD8 was found to upregulate genes associated with phagocytosis in OPCs.
Dysregulated phagocytosis pathways were linked to characteristics of autism.

Abstract

Our results suggest that phagocytosis of excess synapses by OPCs around eye opening is a critical mechanism for visual development, driven by CHD8-mediated upregulation of phagocytosis-related genes. Dysregulation of this pathway is also linked to autism pathology.
