Nitric oxide in plant–fungal interactions

Leukocyte-endothelial cell interactions in nitric oxide synthase-deficient mice.

Nitric oxide (NO) is known to be an important endogenous modulator of leukocyte-endothelial cell interactions within the microcirculation. We examined leukocyte rolling and adhesion under baseline conditions and following thrombin (0.25 U/ml) superfusion in the mesentery of wild-type, inducible NOS (iNOS)-deficient (-/-), neuronal NOS (nNOS) -/-, and endothelial cell NOS (ecNOS) -/- mice to fur...

Nitric Oxide Production and Nitric Oxide

Nitric oxide and the bioactivities

Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...

Is Nitric Oxide a Hormone?

Nitric oxide (NO) is a simple ubiquitous signaling molecule and plays important roles in almost every biological system. Recent evidences suggest that NO may act as an endocrine molecule. The aim of this review is considering available literature on endocrine roles of NO and/or its metabolites, i.e. nitrite and nitrate. Existing data suggest the idea that NO is a hormone that after production i...
