Some long\u2010established lines such as RPMI 1788, CESS and recently established early\u2010passage Epstein\u2010Barr virus (EBV)\u2010transformed lymphoblastoid lines were constitutive IL 6 producers. Other long\u2010established lymphoblastoid lines such as RPMI 8866 and SKW6.4 and all Burkitt lymphomalines tested were nonproducers of IL 6.<\/jats:p><jats:p>Constitutive production of IL 6 in early passage lines could be enhanced by the phorbol ester phorbol 12\u2010myristate 13\u2010acetate (PMA) and recombinant (r)IL 4 but not by rIL 1\u03b1 or rIL 1\u03b2. Nonproducing EBV\u2010transformed lymphoblastoid cell lines could be induced to IL 6 production by PMA, rIL 1\u03b1, IL 1\u03b2 and IL 4. Amongthe nonproducing lines SKW6.4 was induced to IL 6 production by PMA, rIL 1\u03b1, rIL 1\u03b2 and rIL 4, whereas RPMI 8866 was induced only by PMA, to a limited extent by rIL 1\u03b1 and rIL 1\u03b2 but not at all by rIL 4. There was no induction of IL 6 by any recombinant cytokine in the two Burkitt lymphoma lines but measurable production of IL 6 was induced by PMA in one of them (EB4). Cytokines which wereneither enhancers nor inducers of cell lines on their own included rIL 2, rIL 5, interferon (rIFN)\u2010\u03b3, native purified IFN\u2010\u03b1, tumor necrosis factor (rTNF)\u2010\u03b1, rTNF\u2010\u03b2 and purified platelet\u2010derived transforming growth factor\u2010\u03b2. rIL 4 synergized with either rIL 1\u03b1 or rIL 1\u03b2 in the induction of IL 6 in the nonproducing line SKW6.4. Similar effects were also seen in this line with combinations of (a) rIFN\u2010\u03b3 and rIL 4 and (b) IFN\u2010\u03b1 and both rIL 1\u03b1 and rIL 1\u03b2. rIL 4, with or without rIL 1, was more effective than rIL 6 in the induction of IgM synthesis in SKW6.4 and the effect was only partially inhibited by anti\u2010IL 6antiserum at a dose which totally inhibited IL 6\u2010induced IgM production.<\/jats:p><jats:p>Normal peripheral blood lymphocyte populations pre\u2010activated by anti\u2010immunoglobulin rosetting exhibited enhanced production of IL 6 in the presence of rIL 4 and PMA but not in the presence of rIL 1, in contrast to the behavior of adherent mononuclear blood cells which showed IL 4\u2010induced down\u2010regulation of IL 6 production. Human B lymphoblastoid cell\u2010derived IL 6 was shown by Western blotting (using a polyvalent goat antiserum) to be composed of at least three distinct bands between 21 and 30 kDa, andboth constitutively produced and induced activities were neutralized by the same antiserum.<\/jats:p><jats:p>The finding that human B cell lines differ in their constitutive and inducible productionof IL 6, a cytokine implicated in both the growth and differentiation of these cells, is discussed with respect to its possible role as an autocrine factor.<\/jats:p>","DOI":"10.1002\/eji.1830200503","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T12:14:10Z","timestamp":1172751250000},"page":"961-968","source":"Crossref","is-referenced-by-count":14,"title":["Production and regulation of interleukin 6 in human B lymphoid cells"],"prefix":"10.1002","volume":"20","author":[{"given":"David","family":"Hutchins","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian B.","family":"Cohen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Michael Steel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,17]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.3492764"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/bies.950090104"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/MCB.7.1.273"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1084\/jem.167.2.332"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.2829354"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.85.21.8037"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1084\/jem.166.4.967"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/eji.1830171008"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/332083a0"},{"key":"e_1_2_1_11_2","doi-asserted-by":"crossref","first-page":"4116","DOI":"10.4049\/jimmunol.139.12.4116","volume":"139","author":"Brakenhoff J.
