Many brain diseases (such as meningitis, encephalitis, multiple sclerosis (MS), stroke, brain tumors, epilepsy, Alzheimer's disease, AIDS related dementia, Parkinson's disease) are under treated or cannot be treated at all due to the presence of the barriers in the brain (blood-brain barrier, blood-cerebrospinal fluid barrier and the braincerebrospinal fluid barrier). The blood-brain barrier is...
Escherichia coli K1 meningitis occurs following penetration of the blood-brain barrier, but the underlying mechanisms involved in E. coli penetration of the blood-brain barrier remain incompletely understood. We have previously shown that host cytosolic phospholipase A(2)α (cPLA(2)α) contributes to E. coli invasion of human brain microvascular endothelial cells (HBMEC), which constitute the blo...
Impaired blood-brain barrier function represents an important component of hypoxic-ischemic brain injury in the perinatal period. Proinflammatory cytokines could contribute to ischemia-related blood-brain barrier dysfunction. IL-6 increases vascular endothelial cell monolayer permeability in vitro. However, contributions of IL-6 to blood-brain barrier abnormalities have not been examined in the...
To examine whether leukotrienes could increase blood-brain barrier permeability, rats were anesthetized and injected intravenously with Evans blue. Ten microliters of vehicle, of leukotrienes B4, C4, or E4, or of arachidonic acid was injected over 1 hour directly into the brain parenchyma. The percentage of the total surface area of Evans blue extravasation in a coronal section of brain centere...
