AbstractPain initiated or caused by a primary lesion or dysfunction in the nervous system is defined as neuropathic pain. About 75 -150 million people in the United States are suffering for chronic pain disorder. Neuropathic pain has a great impact on the human wellbeing. It is very debilitating and often has an associated degree of depression that contributes to decreasing the quality of life. Moreover, the management of chronic pain is costly to the health care system. Pain is a national healthcare priority in US: the United States Congress has declared the present decade (2001-2010) as the "Decade of Pain Control and Research". Neuropathic pain is a very complex disease, involving several molecular pathways. Due to its individual character, its treatment is extremely difficult. Current available drugs are usually not acting on the several mechanisms underlying the generation and propagation of pain. Nowadays, pain research is focusing on newer molecular ways, such as stem cell therapy, gene therapy, and viral vectors for delivery of biologic anti-nociceptive molecules. These methods could provide a new therapeutic approach to neuropathic pain relief.
