Matrix Metalloproteinases in Cerebral Ischemia

Matrix Metalloproteinases in Cerebral Ischemia

Matrix metalloproteinases (MMPs) are involved in the pathophysiology of several central nervous system diseases that share common pathogeneses, such as disruption of the blood-brain barrier (BBB), neuroinflammation, oxidative stress, and remodeling of the extracellular matrix (ECM). In early ischemic injury, MMPs participate in disruption of the BBB by digesting the basal lamina of capillaries ...

The Matrix Metalloproteinases and Cerebral Ischemia

Dysregulation of the levels of matrix metalloproteinases and tissue inhibitors of matrix metalloproteinases in the early phase of cerebral ischemia.

Metalloproteinases and Tissue Inhibitors of Matrix Metalloproteinases in the Early Phase of Cerebral Ischemia To the Editor: Castellanos et al1 reported increased matrix metalloproteinase (MMP)-9 plasma levels to be an independent risk factor for hemorrhagic transformation in all stroke subtypes. Plasma levels of MMP-9 in patients without hemorrhage were not significantly different from control...

Role of matrix metalloproteinases in delayed neuronal damage after transient global cerebral ischemia.

Mechanisms of selective neuronal death in the hippocampus after global cerebral ischemia remain to be clarified. Here, we explored a possible role for matrix metalloproteinases (MMPs) in this phenomenon. Although many studies have demonstrated detrimental roles for the gelatinase MMP-9 in focal cerebral ischemia, how dysregulated MMP proteolysis influences global cerebral ischemia is less well ...

P 88: Matrix Metalloproteinases in Neuroinflammation

Matrix metalloproteinases (MMPs) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. MMPs have been demonstrated to increase the permeability of the blood–brain barrier (BBB) by degrading the c...
