MedicalResearch.com: What is the background for this study?
Response: Chronic itch is a debilitating symptom that arises from a broad range of etiologies including skin disease, systemic disease, and as a common side-effect of medication. While in the last few decades significant advances in our understanding of the mechanisms underlying chronic itch have been made, a large majority of those advancements were restricted to studies in hairy skin.
Conditions such as plantar and palmar psoriasis, dyshidrosis, and cholestasis, however, are known to exhibit chronic itch restricted primarily to glabrous skin (found on the palms of hands and soles of feet). This is an area that is considered to be particularly debilitating. Therefore, in this study we investigated the role three previously identified pruriceptive neurons (MrgprA3+, MrgprD+, and MrgprC11+) play in mediating acute and chronic glabrous skin itch.
