Itch in atopic dermatitis (AD) is aggravated under warm conditions. Transient receptor potential vanilloid 3 (TRPV3), a member of the thermosensitive TRP channels, is activated by innocuous heat and is abundantly expressed in keratinocytes. The potential role of TRPV3 in itch is illustrated in TRPV3 channelopathies of human and mice. However, the role of TRPV3 in heat-induced itch in AD and the underlying mechanisms are unclear. Here we showed that keratinocytes isolated from patients with AD exhibit enhanced expression and heat sensitivity with hyperactive channel function of TRPV3.

The mast cell –nerve unit classically has represented a fundamental neuroimmune axis in the development of itch because of the traditional prominence of histamine as a pruritogen. However, it is appreciated increasingly that most chronic itch disorders are likely nonhistaminergic in nature, provoking the hypoth esis that other novel effector itch mechanisms derived from mast cells are important. In this review, we present an overview of classical mast cell biology and put these concepts into the context of recent advances in our understanding of the regulation and function of the mast cell–nerve unit in itch biology.

(HAMBURG, Pa.) — The spring breezes of 2020 are carrying more than just tree pollen. There’s a whiff of paranoia in the air. For millions of seasonal allergy sufferers, the annual onset of watery eyes and scratchy throats is bumping up against the global spread of a new virus that produces its own constellation of respiratory symptoms. Forecasters are predicting a brutal spring allergy season for swaths of the U.S. at the same time that COVID-19 cases are rising dramatically. That’s causing angst for people who never have had to particularly worry about their hay fever, other than to stock up on antihista...

Itch, initiated by the activation of sensory neurons, is frequently associated with dermatological diseases. MrgprA3+ sensory neurons have been identified as one of the major itch-sensing neuronal populations. Mounting evidence has demonstrated that peripheral pathological conditions induce physiological regulations of sensory neurons, which is critical for the maintenance of chronic itch sensation. However, the underlying molecular mechanisms are not clear. Here we performed RNA sequencing of genetically labeled MrgprA3+ neurons under both na ïve and allergic contact dermatitis conditions.

lsh S Abstract We were fascinated and heartened to read this very helpful commentary1 on the study by Redhu et al2 who describe some precise physico-biological pathways that link skin barrier disruption to itch in atopic dermatitis (AD). This may well explain how curtailing scratching in AD with the simple behavioural technique of habit reversal can so dramatically improve the condition3. It is important to note that scratching in AD over time often becomes not only a response to itch, but also to both habit and mental state. PMID: 32222068 [PubMed - as supplied by publisher]
