TREND Trauma Related Neuronal Dysfunction

[NOS was first identified by Furchgott (1980) who experimented on the aortas of Rabbits. Since then, the different forms of NO synthase have been classified as

* Neuronal NOS (nNOS or NOS1) which produces NO in neuronal tissue in both the central and peripheral nervous system. Neuronal NOS also performs a role in cell communication and is associated with plasma membranes.
* Inducible NOS (iNOS or NOS2) which can be found in the immune system but is also found in the cardiovascular system. It uses the oxidative stress of NO (a free radical) to be used by macrophages in immune defence against pathogens.
* Endothelial NOS (eNOS or NOS3 or Constitutive / cNOS) generates NO in blood vessels and is involved with regulating vascular function. A constitutive Ca2+ dependent NOS provides a basal release of NO. eNos is associated with plasma membranes surrounding cells and the membranes of Golgi bodies within cells.
