Acid-Sensing Ion Channels and Pain
Pathophysiological conditions such as inflammation, ischemia, infection and tissue injury can all evoke pain, and each is accompanied by local acidosis. Acid sensing ion channels (ASICs) are proton-gated cation channels expressed in both central and peripheral nervous systems. Increasing evidence suggests that ASICs represent essential sensors for tissue acidosis-related pain. This review provi...
متن کاملAcid-sensing ion channels in postoperative pain.
Iatrogenic pain consecutive to a large number of surgical procedures has become a growing health concern. The etiology and pathophysiology of postoperative pain are still poorly understood, but hydrogen ions appear to be important in this process. We have investigated the role of peripheral acid-sensing ion channels (ASICs), which form depolarizing channels activated by extracellular protons, i...
متن کاملLysophosphatidic acid-operated K+ channels.
Lysophosphatidic acid (LPA) is an abundant cellular lipid with a myriad of biological effects. It plays an important role in both inter- and intracellular signaling. Activation of the LPA1-3 G-protein-coupled receptors explains many of the extracellular effects of LPA, including cell growth, differentiation, survival, and motility. However, LPA also acts intracellularly, activating the nuclear ...
متن کاملLysophosphatidic acid as the initiator of neuropathic pain.
The injury-induced intense stimulation of spinal cord neurons causes lysophosphatidic acid (LPA) biosynthesis. LPA(1) receptor activation causes demyelination and sprouting of dorsal root fibers, leading to an induction of synaptic reorganization underlying allodynia, in which innocuous (tactile) stimuli cause intense pain. The LPA(1) signal also initiates the up-regulation of Ca(v)α2δ1 in dors...
