We have shown very recently that normal LC express the high-affinity receptor for IgE (Fc\u03b5RI) which accounts for the binding of monomeric IgE on these cells. In the present study, we investigated the IgE-binding capacity of resident LC on cryosections from skin of normal individuals and from uninvolved and involved skin of patients with atopic eczema, psoriasis, lupus erythematosus and mycosis fungoides. When compared to LC from uninvolved or normal skin, an increased binding of IgE was observed in LC from lesional skin of all four diseases studied here. This binding could be blocked by anti-Fc\u03b5RI mAb. Furthermore, increased IgE binding capacity of LC correlated to an increased expression of Fc\u03b5RI on these cells. These results clearly demonstrate that the expression of Fc\u03b5RI on LC is increased in inflammatory skin areas. Since this phenomenon is observed in several unrelated diseases, it suggests the presence in these conditions of a similar microenvironment which up-regulates the Fc\u03b5RI expression on LC.<\/jats:p>","DOI":"10.1159\/000236249","type":"journal-article","created":{"date-parts":[[2009,9,15]],"date-time":"2009-09-15T08:17:46Z","timestamp":1253002666000},"page":"204-207","source":"Crossref","is-referenced-by-count":17,"title":["In vivo Modulation of the High-Affinity Receptor for IgE (Fc\u03b5RI) on Human Epidermal Langerhans Cells"],"prefix":"10.1159","author":[{"given":"Thomas","family":"Bieber","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johannes","family":"Ring","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,9,2]]},"container-title":["International Archives of Allergy and Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/236249","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000236249","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T11:14:20Z","timestamp":1777634060000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000236249"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,2]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000236249","archive":["Portico"],"relation":{},"ISSN":["1018-2438","1423-0097"],"issn-type":[{"value":"1018-2438","type":"print"},{"value":"1423-0097","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,2]]}}}
