The brain is a major target of the end-organ damage produced by hypertension, and hypertension is a leading risk factor for stroke and dementia. Despite the benefits of anti-hypertensive therapy, the burden of disease caused by hypertension remains substantial, especially in the brain. Cerebral blood vessels are uniquely susceptible to the deleterious effects of hypertension, resulting in pathological alteration of the vascular wall and disruption of BBB permeability leading to major alterations in the composition of the brain microenvironment. Furthermore, we have discovered that hypertension disrupts neurovascular control mechanisms that assure an adequate cerebral blood supply. Loss of these vital homeostatic responses compromises the blood supply to the brain and increases the susceptibility of the brain to vascular insufficiency and ischemic damage.

How hypertension exerts these harmful effects is still uncertain, and elucidating the underlying mechanisms is a necessary step for developing new approaches to prevent stroke and dementia. Our research is particularly focused in elucidating the specific cellular targets through which hypertension alters neurovascular function, and their eventual link to cognitive impairment.

Over the last years, it has been shown that both the innate and the adaptive immune system play a role in the pathogenesis of hypertension and other cardiovascular diseases such as obesity and diabetes. Therefore, we are currently investigating whether peripheral or brain-resident immune cells contribute to the cerebrovascular alterations induced by hypertension and other cardiovascular risk factors.
