Acid Evoked Thermal Hyperalgesia Involves Peripheral P2Y1 Receptor Mediated TRPV1 Phosphorylation in a Rodent Model of Thrombus Induced Ischemic Pain

Abstract

Collectively these data show that maintenance of an acidic environment in the ischemic hind paw of TIIP rats results in the phosphorylation of TRPV1 receptors via a PKC-dependent pathway, which leads to the development of TH mimicking what occurs in chronic ischemic patients with severe acidosis. More importantly, peripheral P2Y1 receptors play a pivotal role in this process, suggesting a novel peripheral mechanism underlying the development of TH in these patients.
