Although sunburn can produce severe uncontrollable itching, the underlying mechanisms of ultraviolet (UV) irradiation-induced itch are poorly understood because of a lack of experimental animal models of sunburn itch. Here we established a sunburn-related mouse model and found that Broad-band UVB (BB-UVB) irradiation elicited scratching but not wiping behavior in mice. By using a combination of live-cell Ca2+ imaging and quantitative RT-PCR on dorsal root ganglion (DRG) neurons, hematoxylin and eosin staining, immunofluorescence staining of skin preparations, behavioral testing, in combination with genetic and pharmacological approaches, we showed that TRPV1-positive DRG neurons but not mast cells are involved in BB-UVB irradiation-induced itch. Moreover, both genetic and pharmacological inhibition of TRPV1 function significantly alleviated BB-UVB irradiation-induced itch response. Collectively, our results suggest that BB-UVB irradiation evokes itch sensation in mice through promoting TRPV1 channel function in DRG neurons and provide potential therapeutic targets for sunburn-related itch.
