Langerhans Cells Express Inducible Nitric Oxide Synthase and Produce Nitric Oxide

EXPRESSION OF INDUCIBLE NITRIC OXIDE SYNTHASE GENE (iNOS) STIMULATED BY HYDROGEN PEROXIDE IN HUMAN ENDOTHELIAL CELLS

Inducible nitric oxide synthase (iNOS) gene expresses a calcium calmudolin-independent enzyme which can catalyse NO production from L-arginine. The induction of iNOS activity has been demonstrated in a wide variety of cell types under stimulation with cytokines and lipopoly saccharide (LPS). Previous studies indicated that all nitric oxide synthases (NOS) activated in human umbilical vein endot...

Oxide in Response to Self- and Alloantigens Nitric Oxide Synthase and Generate Nitric Thymic Dendritic Cells Express Inducible Remuzzi

Inducible nitric oxide synthase and inflammatory diseases.

Nitric oxide (NO) is a colorless gas at room temperature and one of the simplest molecules known, yet it has been implicated in a wide variety of regulatory mechanisms ranging from vasodilatation and blood pressure control to neurotransmission. It is also involved in nonspecific immunity and participates in the complex mechanism of tissue injury as a major mediator of inflammatory processes and...

Inducible nitric oxide synthase and blood pressure.

In the present studies, the influence of inducible nitric oxide synthase (NOS) inhibition with aminoguanidine on renal function and blood pressure was examined in rats. Intravenous aminoguanidine infusion (60 mg x kg-1 x hr-1) for 40 minutes to anesthetized Sprague-Dawley rats (n=7) resulted in no significant changes in mean arterial pressure or renal cortical blood flow, while medullary blood ...

Inducible nitric oxide synthase and vascular injury.

The role nitric oxide (NO) plays in the cardiovascular system is complex and diverse. Even more controversial is the role that the inducible NO synthase enzyme (iNOS) serves in mediating different aspects of cardiovascular pathophysiology. Following arterial injury, NO has been shown to serve many vasoprotective roles, including inhibition of platelet aggregation and adherence to the site of in...
