Abstract

Cultured cells derived from the cerebromicrovasculature can be shown to contain the enzyme nitric oxide synthase (NOS) by NADPH diaphorase staining. Nos is located largely as a distinct crescent adjacent to the nuclear membrane. NOS in these cells appears to be associated with the microtubule and microfilament structures and the Golgi apparatus of the cell as opposed to being freely soluble in the cytoplasm or bound to the plasma membrane. Disruption of the integrity of these structures with colchicine or cytochalasin B causes a change in the subcellular localization of NOS as well as a change in the intensity of staining.

Nitric oxide (NOβ€’), generated by nitric oxide synthase (NOS II) from immunostimulated cells during infection, plays an important role in host immune defense against microbial invasion. The impact of different rates of NOβ€’ production on host cell function has not been defined. Herein, we describe the

## Background: Endothelin (et) is an endothelium-derived multifunctional peptide that produces a potent, long-lasting vasoconstriction. nitric oxide (no), besides being the most important endothelium-derived relaxant factor in blood vessels, is supposed to be involved in regulating the interactions
