However, conditions of persistent NKG2D ligand expression can lead to immunosuppression. In cancer patients, tumor expression and shedding of the MHC class I\u2013related chain A (MICA) ligand of NKG2D drives proliferative expansions of NKG2D+CD4+ T cells that produce interleukin-10 (IL-10) and transforming growth factor-\u03b2, as well as Fas ligand, which inhibits bystander T cell proliferation in vitro. Here, we show that increased frequencies of functionally equivalent NKG2D+CD4+ T cells are inversely correlated with disease activity in juvenile-onset systemic lupus erythematosus (SLE), suggesting that these T cells may have regulatory effects. The NKG2D+CD4+ T cells correspond to a normally occurring small CD4 T cell subset that is autoreactive, primed to produce IL-10, and clearly distinct from proinflammatory and cytolytic CD4 T cells with cytokine-induced NKG2D expression that occur in rheumatoid arthritis and Crohn's disease. As classical regulatory T cell functions are typically impaired in SLE, it may be clinically significant that the immunosuppressive NKG2D+CD4+ T cells appear functionally uncompromised in this disease.<\/jats:p>","DOI":"10.1084\/jem.20081648","type":"journal-article","created":{"date-parts":[[2009,3,16]],"date-time":"2009-03-16T21:09:39Z","timestamp":1237237779000},"page":"793-805","update-policy":"https:\/\/doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":102,"title":["Normally occurring NKG2D+CD4+ T cells are immunosuppressive and inversely correlated with disease activity in juvenile-onset lupus"],"prefix":"10.1084","volume":"206","author":[{"given":"Zhenpeng","family":"Dai","sequence":"first","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cameron J.","family":"Turtle","sequence":"additional","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Garrett C.","family":"Booth","sequence":"additional","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanley R.","family":"Riddell","sequence":"additional","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodore A.","family":"Gooley","sequence":"additional","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne M.","family":"Stevens","sequence":"additional","affiliation":[{"name":"Pediatric Rheumatology, Children's Hospital and Regional Medical Center, Seattle, WA 98105 2"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Spies","sequence":"additional","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronika","family":"Groh","sequence":"additional","affiliation":[{"name":"Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109 1"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[2009,3,16]]},"reference":[{"key":"2023072916445005400_bib1","doi-asserted-by":"crossref","first-page":"875","DOI":"10.1146\/annurev.immunol.17.1.875","article-title":"Regulation of immune responses through inhibitory receptors","volume":"17","author":"Long","year":"1999","journal-title":"Annu.
