Addition of small numbers of purified macrophages to the cultures restores the response to a low level. T-deprived cells show these effects in very much lesser degree. Large numbers of macrophages completely suppress the response of both normal and T-deprived spleen. We conclude that two mechanisms of suppression are at work: a direct effect of macrophages and a macrophage-dependent \"suppressor T cell\" effect.<\/jats:p>","DOI":"10.1084\/jem.136.4.956","type":"journal-article","created":{"date-parts":[[2004,6,23]],"date-time":"2004-06-23T23:23:31Z","timestamp":1088033011000},"page":"956-961","update-policy":"https:\/\/doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":83,"title":["REGULATION OF LYMPHOCYTE RESPONSES IN VITRO"],"prefix":"10.1084","volume":"136","author":[{"given":"Masaru","family":"Yoshinaga","sequence":"first","affiliation":[{"name":"From the Department of Microbiology, Yale School of Medicine, New Haven, Connecticut 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aiko","family":"Yoshinaga","sequence":"additional","affiliation":[{"name":"From the Department of Microbiology, Yale School of Medicine, New Haven, Connecticut 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byron H.","family":"Waksman","sequence":"additional","affiliation":[{"name":"From the Department of Microbiology, Yale School of Medicine, New Haven, Connecticut 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[1972,10,1]]},"container-title":["The Journal of Experimental Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/rupress.org\/jem\/article-pdf\/136\/4\/956\/1654966\/956.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/rupress.org\/jem\/article-pdf\/136\/4\/956\/1654966\/956.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,24]],"date-time":"2023-07-24T20:58:37Z","timestamp":1690232317000},"score":1,"resource":{"primary":{"URL":"https:\/\/rupress.org\/jem\/article\/136\/4\/956\/21823\/REGULATION-OF-LYMPHOCYTE-RESPONSES-IN-VITRO-I"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1972,10,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1972,10,1]]}},"URL":"https:\/\/doi.org\/10.1084\/jem.136.4.956","relation":{},"ISSN":["1540-9538","0022-1007"],"issn-type":[{"value":"1540-9538","type":"electronic"},{"value":"0022-1007","type":"print"}],"subject":[],"published":{"date-parts":[[1972,10,1]]}}}
