Abstract: Inflammatory and neuropathic pains arise in part from sensitization at nociceptive synapses in the spinal cord. Activity-dependent signaling cascades converge onto the tyrosine kinase Src, which participates in augmenting the function of N-methyl-D-aspartate receptors (NMDARs) and thus potentiates the nociceptive system. Src is capable of these effects because it is anchored to the NMDAR complex via an adaptor protein called NADH dehydrogenase subunit 2 (ND2). There is evidence that this interaction occurs between amino acids 40-49 of Src and amino acids 310-321 of ND2. I have determined that a peptide consisting of amino acids 310-321 of ND2, and affixed to the HIV Tat domain for cell permeability, is capable of alleviating tactile allodynia induced by Complete Freund's Adjuvant (CFA) in rats. Src40-49Tat was not effective in two models of inflammatory pain. This work further implicates the Src-ND2 interaction in pain hypersensitivity and suggests that Tat ND2 310-321 may alleviate it.
