The present studies have examined whether diets supplemented with vitamin A acetate (VAA) could enhance induction and elicitation of contact sensitivity to oxazolone in the mouse. Application of 0.3% oxazolone to VAA-fed mice resulted in increased DNA synthesis in the draining lymph nodes and increased ear thickness after challenge, in comparison with mice on a stock (standard) diet. Moreover, VAA-fed (but not control) mice were sensitized to 0.03% oxazolone as shown by DNA synthesis, increased arrival of syngeneic 51Cr-labelled lymphocytes in the draining lymph nodes, and ear swelling after challenge. These findings demonstrate that vitamin A enhances delayed hypersensitivity responses, and point to a role for vitamin A in developing an animal model capable of detecting weak contact sensitizers after topical application.<\/jats:p>","DOI":"10.1159\/000233601","type":"journal-article","created":{"date-parts":[[2009,8,5]],"date-time":"2009-08-05T05:41:56Z","timestamp":1249450916000},"page":"120-125","source":"Crossref","is-referenced-by-count":24,"title":["Enhancement of Contact Sensitization in Mice Fed a Diet Enriched in Vitamin A Acetate"],"prefix":"10.1159","author":[{"given":"Klara","family":"Miller","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanne","family":"Maisey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miroslav","family":"Malkovsk\u00fd","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,8,4]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/233601","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000233601","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T10:40:47Z","timestamp":1777632047000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000233601"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000233601","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,4]]}}}
