Charcot-Marie-Tooth disease (CMT) is the most common inherited motor and sensory neuropathy. Previous studies have found that, according to CMT patients, neuropathic pain is an occasional symptom of CMT. However, neuropathic pain is not considered to be a significant symptom associated with CMT and, as a result, no studies have investigated the pathophysiology underlying neuropathic pain in thi...

Traumatic neuropathic pain caused by traumatic neuroma has long been bothering both doctors and patients, the mechanisms of traumatic neuropathic pain are widely discussed by researchers and the treatment is challenging. Clinical treatment of painful neuroma is unclear. Numerous treatment modalities have been introduced by experts in this field. However, there is still no single standard recogn...

Pain is one of the most debilitating symptoms in epidermolysis bullosa (EB) leading to reduced quality of life. Pain in EB comprises both neuropathic and non-neuropathic qualities. An assessment of pain qualities has not formerly been completed in EB. The Pain Quality Assessment Scale (PQAS) is an adjusted version of the validated Neuropathic Pain Scale and includes 20 pain qualities and descri...

While neuroimmune interactions are increasingly recognized as important in nociceptive processing, the nature and functional significance of these interactions is not well defined. There are multiple reports that the activation of spinal microglia is a critical event in the generation of neuropathic pain behaviors but the mediators of this activation remain disputed. Here we show that the chemo...

Spinal cord injury (SCI) causes chronic pain in 65% of individuals. Unfortunately, current pain management is inadequate for many SCI patients. Rodent models could help identify how SCI pain develops, explore new treatment strategies, and reveal whether acute post-SCI morphine worsens chronic pain. However, few studies explore or compare SCI-elicited neuropathic pain in rats. Here, we sought to...

Neuropathic pain is a common cause of pain after nerve injury, but its molecular basis is poorly understood. In a post-gene chip microarray effort to identify new target genes contributing to neuropathic pain development, we report here the characterization of a novel neuropathic pain contributor, thrombospondin-4 (TSP4), using a neuropathic pain model of spinal nerve ligation injury. TSP4 is m...
