In HZ and PR, HLA-DR was found to be significantly expressed on T cell surfaces (CD3+ cells) when compared to that of the normal control (HZ: p &lt; 0.001, PR: p &lt; 0.05). Among T cell subsets, such HLA-DR antigen was predominantly expressed on suppressor\/cytotoxic cells (CD8+) in HZ (vs. normal control, p &lt; O.01). However, in the case of PR, it was predominantly expressed on helper cells (CD4+; vs. control, p &lt; 0.05). On the other hand, activated T cell antigen (CD25+) was not significantly expressed on T cells (CD3+) in either HZ or PR. In the T cell subsets, HLA-DR antigen expression returned to normal levels during the recovery phases of HZ and PR.<\/jats:p>","DOI":"10.1159\/000247769","type":"journal-article","created":{"date-parts":[[2009,10,13]],"date-time":"2009-10-13T01:54:47Z","timestamp":1255398887000},"page":"160-163","source":"Crossref","is-referenced-by-count":11,"title":["HLA-DR Antigen Expression on Peripheral T Cell Subsets in Pityriasis rosea and Herpes zoster"],"prefix":"10.1159","author":[{"given":"T.","family":"Yoshiike","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Aikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Wongwaisayawan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Ogawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,10,8]]},"container-title":["Dermatologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/247769","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000247769","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T09:29:35Z","timestamp":1777541375000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000247769"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000247769","archive":["Portico"],"relation":{},"ISSN":["0011-9075","2571-7197"],"issn-type":[{"value":"0011-9075","type":"print"},{"value":"2571-7197","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10,8]]}}}
