The present invention relates to the discovery of a novel molecular pathway involved in long-term hyperexcitability of sensory neurons, which, in higher animals, is associated with persistent pain. It is based on the discovery that, following injury to an axon of a neuron, an increase in nitric oxide...http://www.google.com.au/patents/US20060216339?utm_source=gb-gplus-sharePatent US20060216339 - Neuronal pain pathway
