In the initiation phase, pro-hypertensive stimuli including chronic sympathetic nervous system (SNS), high salt intake and imbalanced gut microbes all influence the function of immune cells, contributing to the development of elevated blood pressure. As hypertension progresses, many immune cells, such as macrophages, dendritic cells, NK cells, B and T lymphocytes, accumulate in organs such as the heart, blood vessels, and kidneys.
