Palatine tonsils are secondary lymphoid organs and the major barrier protecting the digestive and respiratory tracts from potential invasive microorganisms. They have been used as sources of lymphoid tissue; however, despite the hundreds of papers published on tonsillectomy, no studies addressing the functionality of the CD4+ and CD8+ T cells from chronically infected tonsils have yet been published. The aim of this study was to analyse the functionality of the CD4+ and CD8+ T cells with respect to tonsillar tissue. We used an affordable approach to measure the frequency of antigen-specific CD4+ T cells, the direct ex-vivo cytotoxicity of CD8+ T cells, memory T cell phenotype, cytokine profile and DC phenotype. Our results demonstrate that CD4+ and CD8+ T cells from tonsillar tissue are totally functional, as shown by their ability to produce cytokines, to degranulate and to differentiate into effector-memory T cells.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2012.04573.x","type":"journal-article","created":{"date-parts":[[2012,2,14]],"date-time":"2012-02-14T08:33:02Z","timestamp":1329208382000},"page":"200-206","source":"Crossref","is-referenced-by-count":29,"title":["Functionality of CD4+ and CD8+ T cells from tonsillar tissue"],"prefix":"10.1093","volume":"168","author":[{"given":"I","family":"Sada-Ovalle","sequence":"first","affiliation":[{"name":"Laboratory of Integrative Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Talayero","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L","family":"Chav\u00e9z-Gal\u00e1n","sequence":"additional","affiliation":[{"name":"Laboratory of Integrative Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L","family":"Barrera","sequence":"additional","affiliation":[{"name":"Laboratory of Integrative Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Castorena-Maldonado","sequence":"additional","affiliation":[{"name":"Sleep Medicine Unit"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Soda-Merhy","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L","family":"Torre-Bouscoulet","sequence":"additional","affiliation":[{"name":"Department of Respiratory Physiology.
