We determined that only low levels of tumor necrosis factor alpha (TNF-\u03b1) are produced in the lungs following infection. Thus, the objective of the present studies was to determine whether treatment with a TNF-\u03b1-expressing adenoviral vector (adenoviral vector with the murine TNF-\u03b1 transgene under the control of the human cytomegalovirus promoter [AdTNF\u03b1]) could switch the type 2 (T2) T-cell response\/T1 T-cell response balance toward the T1 T-cell response. AdTNF\u03b1 induced an increase in TNF-\u03b1 expression at days 3 and 7. At days 7 to 14, the number of cryptococcal lung CFU continued to increase in both untreated and control adenoviral vector (empty adenovirus type 5 backbone)-treated mice, but the number was ultimately 100-fold lower following AdTNF\u03b1 treatment. AdTNF\u03b1 markedly increased neutrophil and macrophage numbers, and pulmonary eosinophilia did not develop. CXCL1, CXCL2, and gamma interferon were also up-regulated, while eotaxin, interleukin-4 (IL-4), and IL-5 were down-regulated. AdTNF\u03b1 treatment also increased the number of CD80<jats:sup>+<\/jats:sup>and CD40<jats:sup>+<\/jats:sup>cells and decreased the number of CD86<jats:sup>+<\/jats:sup>cells (CD11b<jats:sup>+<\/jats:sup>and CD11c<jats:sup>+<\/jats:sup>) in the lungs. Major histocompatibility complex class II levels on CD11b<jats:sup>+<\/jats:sup>cells were increased. Whole-lung expression of inducible nitric oxide synthase was increased, while YM2 expression and acidic mammalian chitinase expression were decreased. None of these effects were observed with the control (empty) adenoviral vector. Overall, these results support the hypothesis that early TNF-\u03b1 expression promotes a shift in T-cell and macrophage polarization from T2\/alternatively activated macrophages toward T1\/classically activated macrophages, resulting in control of the fungal infection and prevention of the allergic response.<\/jats:p>","DOI":"10.1128\/iai.00176-07","type":"journal-article","created":{"date-parts":[[2007,7,24]],"date-time":"2007-07-24T00:54:24Z","timestamp":1185238464000},"page":"4951-4958","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":40,"title":["Modulation of the Pulmonary Type 2 T-Cell Response to<i>Cryptococcus neoformans<\/i>by Intratracheal Delivery of a Tumor Necrosis Factor Alpha-Expressing Adenoviral Vector"],"prefix":"10.1128","volume":"75","author":[{"given":"Jami E.","family":"Milam","sequence":"first","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy C.","family":"Herring-Palmer","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raj","family":"Pandrangi","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roderick A.","family":"McDonald","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary B.","family":"Huffnagle","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine"},{"name":"Department of Microbiology and Immunology, University of Michigan Medical School, Ann Arbor, Michigan 48109"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Galen B.","family":"Toews","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.174.10.6346"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1385\/IR:33:1:053"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.71.1.68-74.2003"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.165.1.158"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1084\/jem.20040035"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.169.3.1182"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.69.4.2723-2727.2001"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/nri978"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.174.2.1027"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.73.1.39-49.2005"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.70.6.2959-2964.2002"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1165\/ajrcmb.13.4.7546779"},{"key":"e_1_3_2_14_2","doi-asserted-by":"crossref","first-page":"2393","DOI":"10.4049\/jimmunol.160.5.2393","volume":"160","year":"1998","unstructured":"Huffnagle, G.
