Clinical Significance
NGF prevents or reduces neuronal degeneration in animal models of neurodegenerative diseases and these encouraging results in animals have led to several clinical trials in humans. NGF has also been shown to promote peripheral nerve regeneration in rats. The expression of NGF is increased in inflammatory diseases where it suppresses inflammation. Also, NGF appears to promote myelin repair. Hence NGF may be useful for the treatment of multiple sclerosis. NGF could also be involved in various psychiatric disorders, such as dementia, depression, schizophrenia, autism, Rett syndrome, anorexia nervosa, and bulimia nervosa. Dysregulation of NGF signaling has also been linked to Alzheimer's disease.
Also, NGF has been shown to play a role in number cardiovascular diseases, such as coronary atherosclerosis, obesity, type 2 diabetes, and metabolic syndrome. Reduced plasma levels of NGF and BDNF have been associated with acute coronary syndromes and metabolic syndromes. NGF is known to have insulinotropic, angiogenic, and antioxidant properties. NGF suppresses food intake.
NGF has also been shown to accelerate wound healing. There is evidence that it could be useful in the treatment of skin ulcers and cornea ulcers.
In some gynecological diseases, an elevated prostaglandin E2 is thought to stimulate production of NGF which contributes to the perception of pain and increased inflammation in endometriosis.
Monoclonal antibodies against NGF have been used in clinical trials to modulate pain. One of these is Tanezumab.

Famous quotes containing the word significance:
“The hypothesis I wish to advance is that ... the language of morality is in ... grave disorder.... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have—very largely if not entirely—lost our comprehension, both theoretical and practical, of morality.”
—Alasdair Chalmers MacIntyre (b. 1929)
