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 ischemic stroke. Specific areas we are interested in include:

  • Acute ischemic stroke and reperfusion injury
  • Cerebrovascular adaptation to pregnancy and preeclampsia/eclampsia
  • Long-term cardiovascular consequences of preeclampsia.

 Specific projects are described below:

Vascular protection for acute ischemic stroke

Ischemic stroke is the leading cause of disability and the fifth leading cause of death in the US, but the second worldwide. 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.

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.

Effect of preeclampsia and eclampsia on cognition and vascular function later in life

It is well-known that the consequences of preeclampsia and eclampsia extend far beyond pregnancy and are associated with excessive cardiovascular and cerebrovascular disease risk later in life, including a 9-fold increased risk of dying from myocardial infarction and a 4- to 5-fold increased risk of stroke. Importantly, former preeclamptic and eclamptic women have poorer cognition and brain atrophy later in life, with increased white matter lesions on magnetic resonance imaging that positively correlate with cognitive defects and decline. The effect of preeclampsia and eclampsia on memory and cognition suggests the hippocampus is adversely affected, a brain region that has a critical role in consolidation of long- and short-term memory and spatial navigation. Our previous studies found that hippocampal arterioles (HAs), small brain arterioles that perfuse the hippocampus, were smaller and stiffer in a model of experimental preeclampsia (ePE) than HAs from normal late-pregnant animals that was associated with mild cognitive impairment. In addition, ePE animals lacked a hyperemic response to seizure that caused greater neuronal injury. Thus, we are also investigating vascular mechanisms of hippocampal injury and cognitive impairment during preeclampsia and eclampsia. We are interested in mechanisms by which HA remodeling and increased stiffness occurs in ePE and if preventing the vascular changes will prevent cognitive impairment. In addition, we are investigating the effect of prolonged and recurrent seizure on hippocampal injury and if preventing HA remodeling will prevent injury during seizure. And lastly, we are investigating if the vascular and cognitive changes persist long-term (months postpartum) in ePE rats. This project aims to provide a greater understanding of the mechanisms by which cognitive impairment occurs in women with preeclampsia and how seizure adversely affects the maternal brain.
