Matrix metalloproteinase expression after human cardioembolic stroke: temporal profile and relation to neurological impairment.
BACKGROUND AND PURPOSE Uncontrolled expression of matrix metalloproteinases (MMPs) can result in tissue injury and inflammation. In animal models of cerebral ischemia, the expression of MMP-2 and MMP-9 was significantly increased. However, their role in human stroke in vivo remains unknown. Therefore, we sought to determine the temporal profile of MMP expression in patients with acute ischemic ...
متن کاملMatrix metalloproteinase expression is related to hemorrhagic transformation after cardioembolic stroke.
BACKGROUND AND PURPOSE In animal models of cerebral ischemia, matrix metalloproteinase (MMP) expression was significantly increased and related to blood-brain barrier disruption, edema formation, and hemorrhagic transformation (HT). MMP inhibitors reduce HT after embolic ischemia in tissue-type plasminogen activator-treated animals. We aimed to determine the relationship between MMPs and HT aft...
متن کاملIncreased brain expression of matrix metalloproteinase-9 after ischemic and hemorrhagic human stroke.
BACKGROUND AND PURPOSE Abnormal expression of some matrix metalloproteinases (MMP) has shown to play a deleterious role in brain injury in experimental models of cerebral ischemia. We aimed to investigate MMP-2 (gelatinase A) and MMP-9 (gelatinase B) in brain parenchyma in both ischemic and hemorrhagic strokes. METHODS Postmortem fresh brain tissue from 6 ischemic and 8 hemorrhagic stroke pat...
متن کاملCD147 (Extracellular Matrix Metalloproteinase Inducer-EMMPRIN) Expression by Human Articular Chondrocytes
Background: Integrins are a family of transmembrane proteins that allow communication between the extracellular matrix and the interior of cells. Chondrocytes, cells of articular cartilage, express integrins and these molecules appear to have a variety of roles including mechanotransduction. Integrins are known to associate with a number of accessory molecules such as CD147 that may act to regu...
متن کاملExpression of Matrix Metalloproteinase-2 and -9 in Meningioma
Background: Meningioma is one of the most common tumors of the central nervous system. It was shown that meningioma had up-regulated expression of Matrix Metalloproteinases (MMPs) that involved in cell growth, angiogenesis and metastasis. Objectives: The aim of the study was the assessment of serum MMP-2 and -9 levels in patients with different grades of meningioma. Materials & Me...
