WebCharcot-Marie-Tooth disease type 1A (CMT1A), the most common inherited demyelinating peripheral neuropathy, is caused by PMP22 gene duplication. Over-expression of wild-type PMP22 in Schwann cells destabilizes the myelin sheath, leading to demyelination and ultimately to secondary axonal loss and disability. WebPeripheral nerve injury (PNI) is a common clinical problem;despite the advances that have been made in understanding the pathophysiological and biological factors related to nerve injury and recovery and the availability of modern diagnostic procedures and advanced microsurgical techniques,the clinical treatment outcome for this condition ...
