Systemic sclerosis (SSc) is a connective tissue disease characterized by tissue fibrosis. One of several complications of SSc, pulmonary arterial hypertension (PAH) can be refractory to treatment, both novel and established. In the present study we investigated the ratio of circulating nitric oxide to endothelin-1 in patients with both SSc and PAH, and determined whether polymorphisms in NOS2 (...
It has been previously reported that although inducible nitric oxide synthase (iNOS) gene knockout (NOS2(-/-)) mice resolve Chlamydia trachomatis genital infection, the production of reactive nitrogen species (RNS) via iNOS protects a significant proportion of mice from hydrosalpinx formation and infertility. We now report that higher in vivo RNS production correlates with mouse strain-related ...
Increased nitric oxide (NO) production by inducible NO synthase (NOS2), an obligate homodimer, is implicated in the cardiovascular sequelae of sepsis. We tested the ability of a highly-selective NOS2 dimerization inhibitor (BBS-2) to prevent endotoxin-induced systemic hypotension, myocardial dysfunction, and impaired hypoxic pulmonary vasoconstriction (HPV) in mice. Mice were challenged with Es...
Abstract Background: Several studies suggested that some traits and polymorphisms in human genome such as G6PD deficiency and other genes have protective effects on susceptibility to malaria infection . Methods: In present study we investigated the prevalence of TNF [1] -244GgA, TNF [1] - 308 GgA,TNF [1] -238GgA, NOS2-954GgC, MBL54GgA, MBL 57GgA, MBL IVSI - 5 GgA polymorphisms and G6P...
AIMS Experimental autoimmune myocarditis (EAM) model mirrors important mechanisms of inflammatory dilated cardiomyopathy (iDCM). In EAM, inflammatory CD133(+) progenitors are a major cellular source of cardiac myofibroblasts in the post-inflammatory myocardium. We hypothesized that exogenous delivery of macrophage-colony-stimulating factor (M-CSF) can stimulate macrophage lineage differentiatio...
Both delta-opioid receptor (DOPr) and cannabinoid-2 receptor (CB2R) agonists attenuate neuropathic pain, but the precise mechanism implicated in these effects is not completely elucidated. We investigated whether nitric oxide synthesized by neuronal (NOS1) or inducible (NOS2) nitric-oxide synthases could modulate DOPr and/or CB2R antiallodynic and antihyperalgesic effects through the peripheral...
In neurocysticercosis, parasite-induced immune suppressive effects are thought to play an important role in enabling site-specific inhibition of inflammatory responses to infections. It is axiomatic that microglia-mediated (M1 proinflammatory) response causes central nervous system inflammation; however, the mechanisms by which helminth parasites modulate microglia activation remain poorly unde...
Madurella mycetomatis is the main causative agent of mycetoma, a tumorous fungal infection characterized by the infiltration of large numbers of neutrophils at the site of infection. In endemic areas the majority of inhabitants have Abs to M. mycetomatis, although only a small proportion of individuals actually develop mycetomal disease. It therefore appears that neutrophils are unable to clear...
The interleukin-12 and gamma interferon (IFN-gamma) pathway of macrophage activation plays a pivotal role in controlling tuberculosis. In the murine model, the generation of supplementary nitric oxide by the induction of the nitric oxide synthase 2 (NOS2) gene product is considered the principal antimicrobial mechanism of IFN-gamma-activated macrophages. Using a low-dose aerosol-mediated infect...
