Welcome to the Sabharwal Lab!
Research
Our research is directed towards understanding neurohumoral control of circulation in health, disease, and aging. Ongoing projects investigate the role of renin-angiotensin system, sympathetic nervous system, and hypothalamic-pituitary adrenal axis in cardiovascular and neurodegenerative diseases. We utilize multidisciplinary and state-of-the art approaches such as radiotelemetry, echocardiography, optogenetics, electrophysiology, in vivo viral gene transfer, molecular biology, Cre-loxP, neuroanatomy etc. to assess cardiovascular and autonomic functions, diurnal rhythms, behavioral neuroscience and neural circuitry in mice. Our ultimate goal is to identify novel therapies that can be translated to yield better clinical outcomes in dilated cardiomyopathy, heart failure, hypertension, mood disorders, Alzheimer’s disease and ALS. The Sabharwal laboratory is funded through National Institute of Health (NIH), American Heart Association (AHA) and internal and external collaborative research awards.
