Electrophysiological Characterization of Internal and External Ligands on TRPA1

TRPA1 is an ion channel expressed on peripheral and spinal sensory neurons and it mediates pain signal transmission. It functions as a cellular sensor for detecting painful mechanical, biochemical and thermal stimuli that cause sensory nerve hyperactivity during chronic pathologies including chronic pain, inflammation, itch and cough. TRPA1 receptor is shown to induce pain hypersensitivity in animal models of diabetic neuropathic pain and its blockade attenuates pain hypersensitivity as well as later loss of the nerve fibers and their function.The Results show different methods of stimulating TRPA1 in high throughput patch clamp experiments with the SyncroPatch 384PE.
