Gelatinase has been partially purified from exudate in the acute phase of carrageenin-induced inflammation in rats. The enzyme occurs in a latent form that can be activated with 4-aminophenylmercuric acetate (APMA). The latent gelatinase was separated into an active gelatinase and a protein fraction
We have previously shown that Arcobacter butzleri induces intestinal, extra-intestinal, and systemic immune responses in perorally infected gnotobiotic IL-10(-/-) mice in a strain-dependent fashion. Here, we present a comprehensive survey of small and large intestinal expression profiles of
Within 1 week following peroral Campylobacter jejuni infection, infant mice develop acute enteritis resolving thereafter. We here assessed colonic expression profiles of mediators belonging to the IL-23/IL-22/IL-18 axis and of matrix-degrading gelatinases MMP-2 and MMP-9 at day 6 post C. jejuni
Neutrophil gelatinase-associated lipocalin (NGAL), a protein found in activated neutrophils, is expressed in kidney tubule cells in response to noxious stimuli, and is thus recognized as a marker of acute kidney injury. Recent studies have suggested that NGAL could also have pathophysiological
The activities of the metalloproteinase gelatinase B, and the presence of IL-6, an inducer of metalloproteinase inhibitors, were investigated in CSF samples of 190 patients with multiple sclerosis (MS; n = 55), optic neuritis (ON; n = 46), other inflammatory neurological diseases (OIND; n = 27) or
BACKGROUND
Neutrophil gelatinase-associated lipocalin (NGAL) binds small, iron-carrying molecules - siderophores. On the other hand, hepcidin is a small defensin-like peptide produced by hepatocytes, modulated in response to anaemia, hypoxia, or inflammation. We tested the hypothesis that NGAL may
It is now apparent that multiple proteinases cooperate in the degradation of the collagenous matrix. Among these proteinases are two biochemically related proteinases which were originally identified by their ability to degrade denatured collagens. The higher molecular weight proteinase (M(r) =
The role of ECM-degrading proteinases in normal developmental processes and in pathological conditions is extensively studied. However, few reports describe the role ECM-degrading proteinases play in modulating hyperalgesia. The goal of this study is to describe the regulation of gelatinases during
This study investigated the use of corrected neutrophil gelatinase-associated lipocalin (cNGAL) values to screen renal dysfunction in patients with systemic inflammation. Plasma NGAL concentrations were measured using a fluorescent immunoassay in 259 patients with inflammatory diseases. An
OBJECTIVE
Climatic droplet keratopathy (CDK) is a degenerative disease of the cornea with possible involvement from matrix metalloproteinases (MMPs). Therefore, the authors investigated histologic distribution, levels, and molecular forms of MMP-2 and MMP-9, as well as tear fluid levels of MMPs and
Gelatinases have been purified from the exudate in the chronic-phase (day 7) of carrageenin-induced inflammation in rats. The day-7 exudate gelatinases gave two peaks on Sephadex G-150 gel filtration, the initial step of the purification. The molecular weights of the gelatinases corresponding to the
Neutral metalloproteinase activities in dermal extracellular space have been studied in several models of prolonged cutaneous inflammation in guinea pigs, by the following techniques: lysis of type I 14C-collagen fibrils, electrophoretic analysis of types I or IV collagen hydrolytic fragments and
Wear debris of polyethylene prosthetic components is known to induce a host granulomatous reaction which recruits numerous macrophages and multinucleated giant cells. By releasing cellular mediators of a nonspecific inflammatory reaction, activated phagocytic cells are thought to play a key role in
Gelatin degrading matrix metalloproteinases in synovial fluid from 21 patients with inflammatory arthritis were shown to consist of two distinct gene products, 92 and 70 kDa gelatinases. The gelatinolytic activity of 92 kDa enzyme, which is released from stimulated neutrophils, was positively
The aim of this study was to clarify whether matrix metalloproteinases (MMP-2 and -9: gelatinases) and pro-inflammatory cytokines [tumor necrosis factor (TNF) alpha and interleukin (IL)-1beta] are induced by heat in tendon tissue in vitro and to test the hypothesis that heat exposure causes
