• isoforms of NOS named according to their site of existence and include inducible NOS (iNOS), endothelial NOS (eNOS), and neuronal NOS (nNOS) [4]. For example, upon bacterial infection in humans, immune cells express iNOS which promotes the release of NO causing inflammation [5] and NO supports defense to

• constitutive isoform of nitric oxide synthase (NOS) found in the CNS. It is believed to play a role in many neurological diseases, including Parkinson’s disease [1], Alzheimer’s disease [2], damage due to stroke [3], and cerebral palsy caused by pre-natal hypoxia [4].
