The focus of this
laboratory is the regulation of the cerebral vasculature,
with an emphasis on elucidating the mechanisms underlying the
vasospasm following 1) subarachnoid hemorrhage, 2) hypocapnia,
and 3) cocaine. Studies are geared towards investigations
into the interplay between these perturbations and the cascade
phenomena that are associated with the eventual constriction,
including the pivotal roles of the endogenous release of the vasoconstrictor,
endothelin-1, and the vasorelaxant, nitric oxide. These
phenomena are studied through angiographic, in situ cranial window
and in vitro tissue bath techniques, using rabbit and rat models.
More recently, the mouse model is being developed to employ genetic
manipulations that will further uncover mechanisms responsible
for the spasms.
