Our results show that the antibodies partially inhibited the concanavalin-A-induced proliferation of normal lymphocytes (32% at 10 \u03bcg\/ml concentration; p &lt; 0.001), whilst they had no significant effects at equivalent doses on the phytohemagglutinin-induced response. A study of the kinetics of this inhibition revealed that the antibodies exerted their effect(s) within the first 24 h of culture (p &lt; 0.001); this is probably due to their interference in early events intimately involved in the de novo synthesis and expression of activation antigens such as HLA-DR and Tac: antibody-treated cultures expressed 51.6 and 41.4% less HLA-DR and Tac, respectively. Two-colour immunofluorescence analysis showed that the specific antibodies bind to a subset of CD8+ cells only.<\/jats:p>","DOI":"10.1159\/000234971","type":"journal-article","created":{"date-parts":[[2009,8,12]],"date-time":"2009-08-12T09:53:17Z","timestamp":1250070797000},"page":"327-333","source":"Crossref","is-referenced-by-count":0,"title":["Pigeon Breeder\u2019s Disease: The Effect of Antigen-Specific Antibodies on in vitro T Cell Responses of Normal Blood Lymphocytes"],"prefix":"10.1159","author":[{"given":"P.J.","family":"Bouic","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.M.","family":"de Beer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Daniels","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.R.","family":"Joubert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,8,6]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/234971","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000234971","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T11:02:32Z","timestamp":1777633352000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000234971"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,6]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000234971","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,6]]}}}
