How schizophrenia genes change brain immune cells that prune synapses

Characterization of schizophrenia liability genes in models of human microglial synaptic pruning

NIH-funded research Massachusetts General Hospital · NIH-11303393

Looks at how genes linked to schizophrenia alter brain immune cells that remove connections, using cells made from people with and without schizophrenia.

What this research studies

The team grows patient-derived brain immune cells (microglia-like cells) and nerve cell fragments in the lab to recreate how connections are trimmed. They use genetic engineering to change specific schizophrenia-linked genes in those cells and watch whether pruning and synapse engulfment change. The work relies on a biobank of cells from people with schizophrenia and matched controls so findings reflect human biology. Results will help pinpoint which genes cause pruning problems and why those changes happen.

Who could benefit from this research

Good fit: Adults with schizophrenia who can donate blood or skin samples (or who have already contributed cells to a biobank) would be ideal candidates for contributing to this research.

Not a fit: People seeking immediate changes to their clinical care or those not able to provide biological samples are unlikely to receive direct benefits from this lab-based work.

Why it matters

Potential benefit: If successful, this could reveal biological targets to protect synapses and guide development of new treatments to improve thinking and function in schizophrenia.

How similar studies have performed: Previous research has shown reduced synapses in schizophrenia and linked the complement C4 gene to pruning, but using patient-derived microglia plus gene editing to test many risk genes is relatively new.
