    Alomone Labs p2x5
    A role for peripheral GDNF signaling in the development of ischemic myalgia. After I/R, injured muscles release a variety of metabolites that include ATP, lactate and protons that stimulate group III and IV muscle afferents. Simultaneously, GDNF is being release in the injured tissues and this induces a signaling cascade in primary sensory neurons through its receptor GFRα1 that involves increased function of CREB/ CREB binding protein (CBP), which in turn modulates the observed overexpression of ATP sensitive channel <t>P2X5</t> and to a lesser degree, ASIC3. This molecular change at the DRG level in turn modulates the appearance of pain-related behaviors such as paw guarding, mechanical hypersensitivity and muscle weakness. In addition, this pathway also affects the exercise pressor reflex after injury. Targeting the overexpression of P2X5 or GFRα1 in sensory neurons or the increased GDNF levels within the muscle appears to inhibit many of these ischemic myalgia-like phenomena.

    Disruption of the CBP/CREB transcription factor complex regulates I/R-related pain-like behaviors, EPRs and P2X5 expression. A . pCREB and CBP are increased after I/R compared to naïve as assessed with western blotting. Penα1 injection however partially blocked the I/R-induced upregulation of pCREB and fully inhibited the upregulation of CBP in the DRGs. B. Paw guarding is increased 1d after I/R in vehicle treated (0.1% DMSO) animals and this is completely prevented by treatment with the CREB-CBP interaction antagonist xx-650-23. Mechanical withdrawal thresholds to VFH stimulation (C) and muscle squeezing (D) are significantly decreased after I/R+0.1%DMSO and I/R+xx-650-23. However, both of these I/R-induced behavioral effects were significantly blunted in xx-650-23 treated animals. E . Decreased grip strength observed 1d after I/R+0.1%DMSO was partially rescued by xx-650-23. F. Exercise pressor reflexes (reflected by changes in MAP after forced running) exacerbated by I/R were also blocked by disruption of the CBP/CREB complex G. xx-650-23 significantly reduced the levels of P2X5 in the DRGs of mice with I/R compared to I/R-injured animals treated with vehicle (0.1% DMSO).
