Similarly, the targeted activation of keratinocyte-expressed TRPV4 elicits itch and the resulting scratching behavior.
Inflammation, Cancer and Immunity—Implication of TRPV1 Channel
WebTwo major types of itch have been identified: histamine-dependent itch, that is thought to require the thermosensitive TRP channel TRPV1 11,12, and nonhistaminergic itch that requires TRPA1 13,14. The TRPA1 agonist cinnamaldehyde (CA) 15,16 was recently reported to elicit a sensation of itch when applied topically to the skin 17,18 .
