BACKGROUND The cytokine and drug interferon-γ enhances superoxide anion production by the antimicrobicidal Nox2 enzyme of neutrophils. Because mature neutrophils have a short lifespan, we hypothesized that the effects of interferon-γ on these cells might be mediated by its prolonged exposure to differentiating neutrophil precursors in the bone marrow rather than its brief exposure to mature cir...
Abstract Chronic granulomatous disease (CGD) is characterized by recurrent bacterial and fungal infections due to reduced nicotinamide adenine dinucleotide phosphate oxidase resulting in impaired production of reactive oxidant species, aberrant inflammation. X-linked CGD (XL-CGD) associated with a mutation the CYBB gene. XL-CGD affects more males, although some females are affected skewed X-ina...
Rheumatoid arthritis (RA) is a chronic inflammatory disease with a heritability of 60%. Genetic contributions to RA are made by multiple genes, but only a few gene associations have yet been confirmed. By studying animal models, reduced capacity of the NADPH-oxidase (NOX) complex, caused by a single nucleotide polymorphism (SNP) in one of its components (the NCF1 gene), has been found to increa...
The most common X-linked recessive form of chronic granulomatous disease (X-CGD) is characterized by the absence of cytochrome b558 in neutrophils. In a rare variant form of X-CGD, cytochrome b558 is present but not functional. The gene (locus symbol CYBB) was localized to band Xp21 by studies of patients with small chromosome deletions. The gene was cloned based on its location and found to en...
Intracerebral levels of Transforming Growth Factor beta (TGFβ) rise rapidly during the onset of experimental autoimmune encephalomyelitis (EAE), a mouse model of Multiple Sclerosis (MS). We addressed the role of TGFβ responsiveness in EAE by targeting the TGFβ receptor in myeloid cells, determining that Tgfbr2 was specifically targeted in monocyte-derived dendritic cells (moDCs) but not in CNS ...
بررسی بیان ژنهای دخیل در سیستم دفاعی گندم نسبت به mycosphaerella graminicola با استفاده از cdna-aflp
aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...
mutations in any of four known nadph-oxidase components lead to cgd. x-linked cgd (x-cgd) is caused by defects in cybb, the gene that encodes gp91-phox. autosomal recessive (ar) cgd is caused by defects in the genes for p47 phox, p22-phox or p67-phox. the aim of this study was to screen the molecular defect in the fetus of an x-cgd carrier mother and postnatal confirmation of the results. in a ...
Heart ischemia is a hypoxia related disease. NOX2 and HIF-1α proteins were increased in cardiomyocytes after acute myocardial infarction. However, the relationship of the hypoxia-induced HIF-1α. NOX2-derived oxidative stress and apoptosis in cardiomyocyte remains unclear. In the current study, we use NOX2 antisense strategy to investigate the role of NOX2 in hypoxia-induced oxidative stress and...
