Among them, PF and PH present itching as a clinical feature; however, the mechanisms behind the pruritus are still unclear. In this report, we sought to investigate the expression of a type 2 inflammation\u2010related pruritogenic cytokine IL\u201031 and its receptor subunit IL\u201031RA through immunofluorescence staining analysis. The number of eosinophils, basophils, and mast cells, and the expression levels of thymic stromal lymphopoietin (TSLP) and periostin were also investigated. Evaluation showed an increase in the number of dermal IL\u201031<jats:sup>+<\/jats:sup> cells and IL\u201031RA<jats:sup>+<\/jats:sup> cells in PH and PVe. Epidermal expression of IL\u201031RA increased in PV, PF, and PVe, but not in PH, compared to healthy individuals. The number of dermal eosinophils and basophils was also increased in PVe and PH. The number of dermal mast cells and expression levels of TSLP and periostin did not change among pemphigus subtypes and healthy controls. Collectively, enhanced IL\u201031\/IL\u201031RA signaling and the increased numbers of dermal eosinophils and basophils may participate in itching in PH. On the other hand, IL\u201031\/IL\u201031RA signaling seemed unable to provoke itching in PVe, a non\u2010pruritic subtype of pemphigus, although it might contribute to epidermal thickening and dermal fibrosis.<\/jats:p>","DOI":"10.1111\/1346-8138.16730","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T08:26:18Z","timestamp":1674030378000},"page":"927-930","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["IL\u201031
