Brain Health
The Program in Brain Health at the Broad Institute is an intellectual community characterizing the genetic and mechanistic basis of brain health and diseases affecting the human brain. Our goal is to break down silos between areas of brain study and turn emerging biological findings into new diagnostic and therapeutic approaches that could benefit the hundreds of millions of people around the world living with these conditions.

Broad scientists discovered that mutations in the C4 gene are key drivers in schizophrenia by affecting synaptic pruning. This is the first time a biological mechanism behind the disease has been described. This image shows human neurons (in blue), with the C4 protein (in green) deposited on synapses. The C4 protein tags synapses for pruning by the microglia, the brain’s immune cells; Broad scientists have demonstrated an overactive version of C4 could result in excessive pruning.
