oxidase/inflammation

Increased reactive oxidant intermediates (ROIs) from primed leukocytes have been implicated in the pathogenesis of acid aspiration lung injury. To evaluate the specific role of the phagocyte NADPH oxidase-derived ROIs in acid lung injury, the p47phox-/- knockout mouse model of chronic granulomatous

Lysyl oxidase (LOX) plays a pivotal role in extracellular matrix (ECM) maturation. Furthermore, novel biological functions has been ascribed to LOX, among them cell differentiation, migration, transformation and regulation of gene expression. In this context, it has been suggested that abnormalities

Lysyl oxidase is a multifunctional enzyme required for collagen biosynthesis. Various growth factors regulate lysyl oxidase during osteoblast differentiation, subject to modulation by cytokines such as TNF-α in inflammatory osteopenic disorders including diabetic bone disease. Canonical Wnt

Neutrophils are primary cells of the innate immune system that generate reactive oxygen species (ROS) and mediate host defense. Deficient phagocyte NADPH oxidase (PHOX) function leads to chronic granulomatous disease (CGD) that is characterized by invasive infections including those by the generally

Patients with chronic granulomatous disease (CGD) have mutated phagocyte NADPH oxidase, resulting in reduced production of reactive oxygen species (ROS). While the mechanism underlying hyperinfection in CGD is well understood, the basis for inflammatory disorders that arise in the absence of evident

Monocyte-derived Dendritic cells (Mo-DC) are a distinct DC subset, involved in inflammation and infection, they originate from monocytes upon stimulation in the circulation and their activation and function may vary in autoimmune diseases. In this study we investigate the differences in Mo-DC

NOX1/NADPH oxidase, a nonphagocytic isoform of reactive oxygen species-producing enzymes, is highly expressed in the colon, but the physiologic and pathophysiologic roles of this isoform are not fully understood. The present study investigated the role of NOX1 in the development of colonic

OBJECTIVE The colitis observed in patients with very early onset inflammatory bowel disease (VEOIBD; defined as onset of disease at younger than 6 years of age) often resembles that of chronic granulomatous disease (CGD) in extent and features of colonic inflammation observed by endoscopy and

Psoriasis is a skin inflammatory disorder that affects 3% of the human population. Although several therapies based on the neutralization of proinflammatory cytokines have been used with relative success, additional treatments are required. The in silico analysis of gene expression data of psoriasis

TH1-type proinflammatory cytokines induce the expression of phagocytic nitric oxide synthase (NOS) and prime the membrane-bound NADPH oxidase of neutrophils and monocytes of mice so as to attain an activated state, which upon a second stimulus releases up to 6-fold increased levels of reactive

Cudrania tricuspidata is a plant used in folk medicine in Korea for treatment of diseases related to oxidative stress and inflammation. In this study the leaf and shoot extract was studied for its antioxidant, anti-inflammatory, and xanthine oxidase (XO) inhibitory activities. The extract with

Human immunodeficiency virus-1 (HIV-1) transactivator of transcription (Tat) is an important viral factor in neuroinflammation. Hindsiipropane B, present in Celastrus hindsii, possesses various biological mechanisms including antiinflammatory activity. In this report, we explored the regulatory

The current study was undertaken to delineate the protective effect of Ginkgolide B, a phyto-constituent from Ginkgo biloba, on oxidized (ox)-LDL-induced endothelial dysfunction via targeting Lectin-like ox-LDL-receptor-1 (LOX-1), NADPH oxidase 4 (NOX-4), and other inflammatory proteins. Our results

Inflammatory changes in the cerebral network are present in early mechanisms involved in neurodegenerative disease, Alzheimer disease (AD), and aging brain. We intended to verify that these are likely due to an activation of NADPH oxidase (NOX) and endoplasmic reticulum (ER) stress. Apocynin (APO)
