alpha mannosidase/inflammation

BACKGROUND Endothelial cell responses during inflammation are heterogeneous and key for selectivity in how leukocytes hone in on specific sites and why vascular diseases are highly bed specific. However, mechanisms for this specificity remain unclear. RESULTS Here, we exposed human endothelial cells

The activation of leukocytes by particulates is a critical event in certain inflammatory syndromes, including acute gout associated with microcrystals of monosodium urate monohydrate. In this study we have evaluated mechanisms of human neutrophil activation by urate crystals. Both

Kujigamberol is the norlabdane compound isolated from Kuji amber and has recently been shown to prevent Ca2+-signal transduction and exert anti-allergy effects in vitro and in vivo. However, the anti-inflammatory activities of kujigamberol remain unclear. In the present study, we investigated the

Liver fibrosis was produced in rats by subcutaneous injections of carbon tetrachloride. The effect of anti-inflammatory steroids (hydrocortisone, prednisone, dexamethasone) on the activity of serum lysosomal hydrolases (beta-N-acetylglucosaminidase, beta-glucosidase and alpha-mannosidase) was

OBJECTIVE HLA-B27 forms misfolded heavy chain dimers, which may predispose individuals to inflammatory arthritis by inducing endoplasmic reticulum (ER) stress and the unfolded protein response (UPR). This study was undertaken to define the role of the UPR-induced ER-associated degradation (ERAD)

A microassay technique for the evaluation of synovial fluid alpha-mannosidase activity is presented with the evaluation of 184 synovial fluid samples from a variety of arthropathic conditions. The results indicate a close correlation of enzyme activity with synovial fluid cell count and the degree

Endothelial-monocyte interactions are regulated by adhesion molecules and key in the development of vascular inflammatory disease. Peroxisome proliferator-activated receptor (PPAR) γ activation in endothelial cells is recognized to mediate anti-inflammatory effects that inhibit monocyte rolling and

Monocyte extravasation through the endothelial layer is a hallmark of atherosclerotic plaque development and is mediated by heavily N-glycosylated surface adhesion molecules, such as intercellular adhesion molecule-1 (ICAM-1). N-glycosylation is a key co- and post-translational modification that

Inflammatory bowel disease (IBD) is a refractory disease of the gastrointestinal tract that is believed to develop in genetically susceptible individuals. Glycosylation, a type of post-translational modification, is involved in the development of a wide range of diseases, including IBD, by

Cervical cancer, caused by high oncogenic risk Human Papillomavirus (HPV) infection, continues to be a public health problem, mainly in developing countries. Using peptide phage display as a tool to identify potential molecular targets in HPV associated tumors, we identified α-mannosidase, among

OBJECTIVE To investigate whether the activity of lysosomal enzymes is increased in the peritoneal fluid of patients with gynecologic cancers compared to activity in the peritoneal fluid from normal subjects and those with pelvic inflammatory disease, and fluid from benign ovarian

Autoimmune diseases are prevalent and often life-threatening syndromes, yet the pathogenic triggers and mechanisms involved remain mostly unresolved. Protein asparagine linked- (N-) glycosylation produces glycan structures that substantially differ among the extracellular compartments of

The activities of several lysosomal hydrolases (beta-galactosidase, beta-hexosaminidase, alpha-mannosidase, beta-glycuronidase and acid phosphatase) were determined in serum and blood lymphocytes from patients affected with scleroderma. Statistical comparisons between means of patient and control

α-1,2 mannosidases, key enzymes in N-glycosylation, are required for the formation of mature glycoproteins in eukaryotes. Aberrant regulation of α-1,2 mannosidases can result in cancer, although the underlying mechanisms are unclear. Here, we report the distinct roles of α-1,2 mannosidase subtypes

The mechanisms that mediate accelerated atherosclerosis in autoimmune diseases remain unclear. One common mechanism that has been documented in autoimmune diseases and atherosclerosis is formation of hypoglycosyalted N-glycans on the cell surface. In this study we tested the effects of swainsonine,
