In human skin, keratinocytes produces IL-6, although the in vivo role of this cytokine is unknown. In the present study we investigated the in situ localization of IL-6 in normal epidermis (n = 10) and in a group of skin diseases characterized by epidermal atrophy. Formalin-fixed paraffin-embedded skin biopsies from patients with clinical and histopathological features consistent with localized scleroderma (n = 10), systemic scleroderma (n = 5), lichen sclerosus et atrophicus (n = 9) and balanitis xerotica obliterans (n = 7) were tested using polyclonal antibodies and avidin-biotinperoxidase immunostaining. We demonstrated the presence of IL-6 in normal epidermis and in atrophic skin diseases. In normal skin there was moderate intercellular and intracellular reactivity detected using a high antibody concentration. In specimens with epidermal atrophy we detected intense cytoplasmic and intercellular immunostaining using a lower antibody concentration. The immunoreactivity was independent of the epidermal thickness. Plasma IL-6, measured by radioimmunoassay, was not elevated in plasma from patients with localized or systemic scleroderma. Increased IL-6 in the epidermis of selected skin diseases suggests that IL-6 may be related to the pathophysiology of dermatologic diseases characterized by epidermal atrophy.<\/jats:p>","DOI":"10.1159\/000236334","type":"journal-article","created":{"date-parts":[[2009,9,15]],"date-time":"2009-09-15T08:17:46Z","timestamp":1253002666000},"page":"44-49","source":"Crossref","is-referenced-by-count":17,"title":["In situ Localization of lnterleukin-6 in Normal Skin and Atrophic Cutaneous Disease"],"prefix":"10.1159","author":[{"given":"Luz I.","family":"Romero","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie H.","family":"Pincus","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\/236334","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000236334","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T11:15:45Z","timestamp":1777634145000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000236334"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,2]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000236334","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]]}}}
