The DISC1 gene is involved in nerve cell growth, signaling, and neuroplasticity (the ability of the brain to grow and adjust throughout a person’s lifetime). Impairment of DISC1 functionality can lead to schizophrenia-like symptoms. Caveolin (Cav-1) is a cell membrane protein that promotes nerve signaling and neuroplasticity in the nervous system. In this study, researchers from the University of California, San Diego looked at the interaction between Cav-1 and DISC1 in the nerve cells of mice and find that the Cav-1 protein regulates the function of DISC1. The study’s findings have significant implications for schizophrenia treatment.
