A common complication associated with diabetes is painful or painless diabetic peripheral neuropathy (DPN). The mechanisms and determinants responsible for these peripheral neuropathies are poorly understood. Using both streptozotocin (STZ)-induced and transgene-mediated murine models of type 1 diabetes (T1D), we demonstrate that Transient Receptor(More)
BACKGROUND Transient receptor potential Vanilloid (TRPV) receptors are involved in nociception and are expressed predominantly in sensory neurons. TRPV1, a non-selective cation channel has been extensively studied and is responsible for inflammatory thermal hypersensitivity. In this study, the expression and function of TRPV4 have been characterized and(More)
Chronic pain is a major clinical problem and opiates are often the only treatment, but they cause significant problems ranging from sedation to deadly respiratory depression. Resiniferatoxin (RTX), a potent agonist of Transient Receptor Potential Vanilloid 1 (TRPV1), causes a slow, sustained and irreversible activation of TRPV1 and increases the frequency(More)
AIM To investigate the effects of selective knockdown of TRPV1 channels in the lower thoracic and upper lumbar segments of spinal cord, dorsal root ganglia (DRG) and mesenteric arteries on rat blood pressure responses to high salt intake. METHODS TRPV1 short-hairpin RNA (shRNA) was delivered using intrathecal injection (6 μg · kg(-1) · d(-1), for 3 d).(More)
Transient Receptor Potential Vanilloid 1 (TRPV1) expressed in peripheral terminals is responsible for transducing thermal and chemical nociception. Role of TRPV1 expressed in the central terminals is not clear, however, its activation modulates synaptic transmission and contributes to central sensitization. In this study, we have determined the role of(More)
