The well-established trophic role of CNTF upon neurons led to performing clinical trials in patients of neurodegenerative diseases. However, trials were suspended due to side effects such as severe weight loss, hyperalgesia, coughing, muscle cramps and pain. So far it is not known how CNTF triggers the problems related to skeletal muscle cramps and pain. CNTF has also been described as a myotrophic factor for denervated skeletal muscles, but the possibility that it affects innervated muscles has also been considered. Since a myotrophic factor could be a valuable tool for treatment of several muscle diseases, we studied the effects of low doses of CNTF delivered systemically by an osmotic pump, over the electrical and mechanical properties of innervated and... |
