Our laboratory studies the cerebral circulation under physiological and pathological conditions. In particular, we are interested in how changes in cerebrovascular structure and function affect cerebral blood flow regulation and hemodynamics in ways that could promote brain injury. In addition, we are interested in blood-brain barrier properties and how changes in permeability to water or solutes can promote injury, including seizure and white matter lesions. Specific areas we are interested in include:
- Acute ischemic stroke and reperfusion injury
- Mechanisms and treatment of small vessel disease
- Cerebrovascular adaptation to pregnancy and preeclampsia/eclampsia
Specific projects are described below:
Vascular protection for acute ischemic stroke
Ischemic stroke is the leading cause of disability and the fourth leading cause of death in the US. The ability of the cerebral circulation to function and supply oxygen and nutrients to the brain after stroke defines the extent of reperfusion and ultimately determines stroke outcome. In our lab, we are focused on studying how ischemia and reperfusion influences the normal behavior of the cerebral arteries and arterioles. We use an established model of stroke - the middle cerebral artery occlusion model MCAO) - to investigate underlying mechanisms of damage to the cerebral vasculature and what treatments will prevent the damage, ie., provide vascular protection.
Ischemic small vessel disease (SVD)
Cerebral SVD is a common age- and hypertension-related vasculopathy of the penetrating and parenchymal arterioles in the brain that causes lacunar stroke, white matter lesions and vascular dementia. The major pathology underlying SVD involves hypertension-induced structural alterations in the parenchymal arterioles, including thickening of the vessel wall and reduced lumen size that leads to loss of autoregulation and a state of chronic hypoperfusion of the white matter. Localized increased blood-brain barrier (BBB) permeability of PA is also involved in SVD pathology by causing focal edema and passage of damaging proteins and serum constituents into the brain parenchyma that can damage white matter. Our goal is to understand how parenchymal arterioles are uniquely affected by chronic hypertension to promote SVD and to selectively treat PA to reverse these detrimental effects.
Adaptation of the cerebral circulation to pregnancy and preeclampsia
Hypertension is a serious complication of pregnancy that occurs in ~5-8% of all pregnancies. While numerous organs are affected by hypertension in pregnancy, cerebrovascular involvement is the direct cause of death in approximately 40% of patients. Neurologic complications can occur in preeclampsia and cause severe and persistent headaches, uncontrolled vomiting, seizure and coma. The major cerebrovascular changes that occur have been shown to be similar to hypertensive encephalopathy in which an acute elevation in blood pressure overcomes the myogenic vasoconstriction of the cerebral arteries and arterioles causing autoregulatory failure, hyperperfusion and edema formation. In addition, blood-brain barrier disruption can cause passage of damaging serum proteins and constituents into the brain parenchyma, causing seizure. However, a fair number of women have seizure during pregnancy at normal blood pressures with seemingly uncomplicated pregnancy. Thus, we are interested in how both normal pregnancy and hypertension in pregnancy affect the cerebral circulation in ways that promote neurologic symptoms, including seizure.
