WebbNerve growth factor (NGF) is a neurotrophin that has been implicated in pain signaling, apoptosis, inflammation and proliferation. The resultant effects depend on interaction with two different receptors; tyrosine kinase A (TrkA) and p75 NTR.NGF increases in synovial fluid from osteoarthritic joints, and monoclonal antibody therapy is trialed to treat … Webbneuromuscular junction, also called myoneural junction, site of chemical communication between a nerve fibre and a muscle cell.
