Angiotensin Receptors and Age Related Mitochondrial Decline in HIV Patients

This study is designed to evaluate specific factors in mitochondria that may precipitate premature aging and physical weakness in HIV patients. Angiotensin receptors 1 and 2 (AT1R and AT2R) are found in virtually every cell type. This study will evaluate how the relationships among these receptors in immune and skeletal muscle cells change with HIV, and how these changes might trigger mitochondrial dysfunction, declines in muscle strength, and cellular decline in people living with HIV.
