Irina Conboy is one of the principal partners of a new joint study on the aging brain. Conboy, an expert in aging and blood-based rejuvenation, will partner with Yi Zuo, a professor of molecular, cell and developmental biology at UC Santa Cruz, and Philippe Mourrain, a professor of psychiatry and behavioral sciences at Stanford University. The group are looking specifically at changes to blood composition and how immune cells in the brain and central nervous system called microglia alter cognition with age, hoping to identify therapeutic interventions.
