Hypertension is a leading cause of worldwide morbidity and mortality, leading to stroke, myocardial infarction, vascular disease, and chronic kidney disease. Emerging evidence from our laboratory and others indicates that hypertension is an inflammatory process in which T cells and T cell-derived cytokines play a central role. Despite this evidence, there are currently no treatments for hypertension that target the immune system. We were the first to demonstrate a critical role for the pro-inflammatory cytokine, interleukin 17A (IL17A), in angiotensin II induced hypertension and vascular dysfunction. When given angiotensin II, mice lacking IL17A have reduced blood pressure and preserved vascular function compared to normal mice. Recent data demonstrates that salt can directly influence naive T cells to differentiate into IL17 producing cells. How T cells can sense and respond to salt is unknown. My current research focus is how T cells and T cell-derived cytokines promote hypertension and renal/vascular dysfunction.
