Abstract

Nerve growth factor (NGF) is largely known as a target-derived factor responsible for the survival and maintenance of the phenotype of specific subsets of peripheral neurones and basal forebrain cholinergic nuclei during development and maturation. However, NGF also exerts a modulatory role on sensory, nociceptive nerve physiology during adulthood that appears to correlate with hyperalgesic phenomena occurring in tissue inflammation. Other NGF-responsive cells are now recognized as belonging to the haemopoietic-immune system and to populations in the brain involved in neuroendocrine functions. The concentration of NGF is elevated in a number of inflammatory and autoimmune states in conjunction with an increased accumulation of mast cells. Mast cells and NGF appear to be involved in neuroimmune interactions and tissue inflammation, with NGF acting as a general 'alert' molecule capable of recruiting and priming tissue defence processes following insult as well as systemic defensive mechanisms. Moreover, mast cells themselves produce NGF, suggesting that alterations in normal mast cell behaviours can provoke maladaptive neuroimmune tissue responses whose consequences could have profound implications in inflammatory disease states. This review discusses recent discoveries involving novel and diverse biological activities of this fascinating molecule.
