Changes in the permeability properties of the tight junction have been reported in AD, and reversing this leaky tight junction may be a potential treatment for AD. This study aimed to determine the effect of larazotide, an antagonist of the protease-activated receptor 2, on the permeability and barrier properties of the tight junctions in keratinocyte monolayers. Normal human epithelial keratinocytes were grown in culture on permeable supports. The effects of larazotide on transepithelial resistance and permeability properties of keratinocyte monolayers were studied before and after histamine challenge. Larazotide mitigated the disruptive effect of histamine on epithelial permeability by increasing the electrical resistance and decreasing epithelial permeability. Larazotide may be beneficial as a topical therapeutic for AD; however, the permeability properties of the short-peptide larazotide through the uppers layers of the epidermis is currently unknown. In conclusion, the protease-activated receptor 2 antagonist larazotide has a protective effect on keratinocyte monolayers and may be useful as an adjunct therapeutic agent to enhance barrier function and promote epidermal healing in AD.</div></div>","PeriodicalId":73548,"journal":{"name":"JID innovations : skin science from molecules to population health","volume":"5 4","pages":"Article 100369"},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143869058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the effects of carvedilol and its enantiomers on UV-induced immunosuppression using contact hypersensitivity (CHS) response in SKH-1 mice. A single-dose UVR (224 mJ/cm²) strongly suppressed CHS, which was attenuated by intraperitoneal injection of carvedilol before UV exposure. Adoptive transfer of lymphocytes isolated from UV-irradiated mice to naïve mice without UV exposure triggered CHS suppression, which was not observed for lymphocytes isolated from carvedilol-treated mice. Topically applied carvedilol also prevented UV-induced CHS suppression. Both the β-blocking S-carvedilol and non–β-blocking R-carvedilol attenuated UV-induced CHS suppression. To evaluate the role of β2-adrenergic receptor, a knockout mouse model of β2-adrenergic receptor on the SKH-1 background was used. UV suppressed CHS in β2-adrenergic receptor–knockout mice, and carvedilol attenuated UV-induced CHS suppression in both genotypes. Furthermore, wild-type and knockout mice exposed to chronic UVR developed skin tumors with similar incidence, multiplicity, and tumor burden, whereas carvedilol inhibited skin tumor development in both genotypes. These data suggest that carvedilol prevents skin cancer not through β-blocking but through its activity overcoming UV-induced immunosuppression.</div></div>","PeriodicalId":73548,"journal":{"name":"JID innovations : skin science from molecules to population health","volume":"5 3","pages":"Article 100365"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
