Peripheral blood cells, either whole mononuclear cell populations or selectively enriched populations, were obtained from a patient with well-established actinic reticuloid. The patient had an expansion of circulating T lymphocytes expressing the suppressor\/cytotoxic phenotype, i.e., CD3+, CD4-, CD8+. A proportion of these cells also expressed the Fc receptor for IgG. Functional studies, including pokeweed mitogen-driven immunoglobulin synthesis, mitogen and alloantigen response, natural killer and antibody-dependent cellular cytotoxicity were within normal ranges and suggested a polyclonal rather than monoclonal expansion. The present functional data extend previous phenotypic studies and support the hypothesis that a chronic reactive immunoregulatory disorder is involved in actinic reticuloid, as has been hypothesized for other T cell chronic proliferations.<\/jats:p>","DOI":"10.1159\/000205201","type":"journal-article","created":{"date-parts":[[2009,2,20]],"date-time":"2009-02-20T14:45:47Z","timestamp":1235141147000},"page":"175-178","source":"Crossref","is-referenced-by-count":0,"title":["Functional Profile of Expanded Suppressor\/Cytotoxic Lymphocyte Population in a Patient with Actinic Reticuloid"],"prefix":"10.1159","author":[{"given":"Andrea","family":"Fattorossi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuliana","family":"De Sanctis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maurizio","family":"Zampetti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefano","family":"Calvieri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,2,20]]},"container-title":["Acta Haematologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/205201","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000205201","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T12:07:33Z","timestamp":1777464453000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000205201"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,2,20]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000205201","archive":["Portico"],"relation":{},"ISSN":["0001-5792","1421-9662"],"issn-type":[{"value":"0001-5792","type":"print"},{"value":"1421-9662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,2,20]]}}}
