How a protein in brain immune cells (MEF2C) shapes early brain wiring and autism

The Contribution of Microglial MEF2C to Brain Development

NIH-funded research University of California, San Diego · NIH-11249989

This project looks at whether the protein MEF2C in brain immune cells (microglia) changes how the brain wires itself and contributes to autism and intellectual disability, especially in children with MEF2C changes.

What this research studies

Researchers will study MEF2C in microglia using lab-grown human cells and animal models to see how it affects synapse pruning and retention during development. They will compare microglial MEF2C activity across ages and in models of MEF2C haploinsufficiency to link molecular changes to brain wiring. The team will use both in vitro experiments and in vivo approaches to observe effects on neural connections and behavior. Findings will be compared to human data to connect the laboratory results to the symptoms seen in MEF2C-related autism.

Who could benefit from this research

Good fit: Ideal candidates for any future human participation would be children or adults with MEF2C haploinsufficiency or autism spectrum disorder, and families willing to donate samples or join clinical follow-up.

Not a fit: People with autism who do not have MEF2C genetic changes may not receive direct benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could point to new biological targets that might lead to treatments reducing social, communication, or cognitive difficulties in people with MEF2C-related autism.

How similar studies have performed: Microglia have been implicated in brain development in prior studies, but directly targeting MEF2C in microglia is a relatively new and unproven approach.
