Unveiling Schizophrenia's Origins: Brain Organoids and Genetic Clues

Two studies published in Biological Psychiatry shed light on the neurodevelopmental origins of schizophrenia. In the first study, researchers used brain organoids grown from patients' skin cells to identify persistent axonal dysregulation as an early contribution to schizophrenia risk. The second study focused on a schizophrenia risk gene, CYFIP1, and found that it affects the behavior and function of microglia, the brain's immune cells, which play a crucial role in synaptic pruning. These findings highlight the importance of non-neuronal cells in understanding and potentially treating neuropsychiatric disorders.
