Transient receptor potential (TRP) ion channels are important mediators of somatosensory signaling throughout the body. Our understanding of the contribution of TRPs to a multitude of cutaneous physiologic processes has grown substantially in the past decade. TRP cation channel subfamily V member 1 (TRPV1), one of the better-understood members of this large family of ion channels, affects multiple pathways involved in pruritus. Further, TRPV1 appears to play a role in maintaining skin barrier function. Together, these properties make TRPV1 a ripe target for new therapies in atopic dermatitis. Neurokinin antagonists may affect similar pathways and have been studied to this effect. Early trials data suggest that these therapies are safe, but assessment of their efficacy in atopic dermatitis is pending as we await publication of phase II and III clinical trials data.
