OBJECTIVE Matrix metalloproteinase-9 (MMP-9) represents a promising marker for acute stroke management. In clinical studies MMP-9 has been quantified by ELISA using differing protocols. We aimed to establish a valid protocol by evaluation of preanalytics. METHODS Blood from stroke patients (n=28)

Several traditional vascular risk factors are associated with proinflammatory alterations, including leukocyte activation, and predispose cerebral vasculature to thrombogenesis on inflammatory stimulation. PMN elastase derived from the activated neutrophils might play an important role in injury.

Our objective is to develop a new therapy for the treatment of stroke. Currently, the only effective therapy for acute ischemic stroke is the thrombolytic agent recombinant tissue plasminogen activator. α1-Antitrypsin (AAT), a serine proteinase inhibitor with potent anti-inflammatory,

Cerebrovascular deposition of fibrillar 39-42 amino acid amyloid beta-protein (Abeta), a condition known as cerebral amyloid angiopathy (CAA), is a key pathological feature of Alzheimer's disease and related disorders including hereditary cerebral hemorrhage with amyloidosis-Dutch type (HCHWA-D).

Cystatins are the thiol Proteinase inhibitors, present ubiquitously in mammalian body. They prevent unwanted proteolysis and play important role in several diseases. Regulation of cysteine Proteinase and their inhibitors is of utmost importance in neurodegenerative diseases like Alzheimer, amyloid

The Kunitz-type proteinase inhibitor, tissue factor pathway inhibitor (TFPI), is the only endogenous inhibitor of the tissue factor (TF)-mediated coagulation pathway that plays a dominant role in normal haemostasis. TFPI exerts its action by binding to factor Xa (FXa) forming a TFPI-FXa complex that

BACKGROUND Carriers of the factor V Leiden mutation (FVL) are resistant to activated protein C proteolysis. Therefore, they are at increased risk of thromboembolic events. Aprotinin is an unspecific proteinase inhibitor frequently used during cardiac surgery procedures to reduce bleeding. However,

Matrix metalloproteinases (MMPs) are either secreted or membrane-bound proteases, capable to degrade extracellular matrix (ECM) proteins as well as a large number of non-ECM proteins, such as growth factors, cytokines, chemokines, cell surface receptors, serine proteinase inhibitors and other MMPs.

Protein Z (PZ) is a vitamin K dependent factor identified in human plasma in 1984 whose physiological function was poorly understood. It was recently shown that protein Z is implicated in the down-regulation of coagulation by forming a complex with a plasma proteinase inhibitor called protein

Radiolabeled C-5-disubstituted pyrimidine-2,4,6-triones have recently been suggested by our group as a class of potent matrix metalloproteinase (MMP) targeted radiotracers that can noninvasively visualize activated MMPs by means of positron emission tomography (PET). MMPs belong to the zinc- and

Hereditary CNS amyloid angiopathy occurring in Icelanders is the first human disorder known to be caused by deposition of cystatin C amyloid fibrils in the walls of the brain arteries leading to single or or multiple strokes with fatal outcome. One or more affected members have been verified by

Knowledge about molecular pathology of hereditary cystatin C amyloid angiopathy (HCCAA), also called hereditary cerebral hemorrhage with amyloidosis, Icelandic type, has increased greatly in the last decade. The disorder has an autosomal dominant mode of inheritance and causes fatal brain hemorrhage

Neuroserpin, a member of the Serine Proteinase Inhibitor (Serpin) superfamily, is known to be a neuroprotective factor in the focal ischemic stroke followed by reducing the microglial activation. Neuroserpin is a protein rich of methionine residues that can scavenge the free radical species which

Neuroserpin, a recently identified inhibitor of tissue-type plasminogen activator (tPA), is primarily localized to neurons within the central nervous system, where it is thought to regulate tPA activity. In the present study neuroserpin expression and its potential therapeutic benefits were examined
