We tested whether differential responses to histamine-dependent and -independent pruritogens can be evoked in ICD induced by sodium lauryl sulfate (SLS). An ICD mouse model was established with 5% SLS in acetone versus a vehicle topically applied for 24 h to the cheek. Site-directed itch- and pain-like behaviors, occurring spontaneously and in response to mechanical, thermal, and chemical stimuli (histamine, \u00df-alanine, BAM8-22, and bradykinin) applied to the cheek, were recorded before (day 0) and after irritant removal (days 1, 2, 3, and 4). Skin inflammation was assessed through visual scoring, ultrasound, and measurements of skin thickness. SLS-treated mice exhibited hyperalgesia-like behavior in response to mechanical and heat stimuli on day 1 compared to the controls. SLS mice exhibited more spontaneous wipes (pain) but not scratching bouts (itch) on day 1. Pruritogen injections caused more scratching but not wiping in SLS-treated mice compared to the controls. Only bradykinin increased wiping behavior compared to saline. SLS-treated mice developed noticeable erythema, scaling, and increased skin thickness on days 1 and 2. SLS induced cutaneous inflammation and behavioral signs of spontaneous pain and itching, hyperalgesia to mechanical and heat stimuli and a chemical algogen, and enhanced itch response to pruritogens. These sensory reactions preceded the inflammation peak and lasted up to two days.<\/jats:p>","DOI":"10.3390\/ijms25147718","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T18:17:32Z","timestamp":1721067452000},"page":"7718","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Itch and Pain Behaviors in Irritant Contact Dermatitis Produced by Sodium Lauryl Sulfate in Mice"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9045-203X","authenticated-orcid":false,"given":"Nathalie M.","family":"Malewicz-Oeck","sequence":"first","affiliation":[{"name":"Clinics for Anesthesiology, Intensive Care and Pain Medicine, University Hospital of Ruhr University Bergmannsheil Bochum, 44789 Bochum, Germany"},{"name":"Department of Anesthesiology, Yale University School of Medicine, 330 Cedar St., New Haven, CT 06510, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhe","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Yale University School of Medicine, 330 Cedar St., New Haven, CT 06510, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven G.","family":"Shimada","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Yale University School of Medicine, 330 Cedar St., New Haven, CT 06510, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert H.","family":"LaMotte","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Yale University School of Medicine, 330 Cedar St., New Haven, CT 06510, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e781","DOI":"10.1097\/PR9.0000000000000781","article-title":"Differences in itch and pain behaviors accompanying the irritant and allergic contact dermatitis produced by a contact allergen in mice","volume":"4","author":"Zhang","year":"2019","journal-title":"Pain.
