The host cell transcription machinery associated with the specific IL-12 induction observed during L. major infection remains to be thoroughly elucidated. In this study, we used Affymetrix GeneChip (Affymetrix) to globally assess the host cell genes and pathways associated with early L. major infection in human myeloid-derived DCs. Our data revealed 728 genes were significantly differentially expressed and molecular signaling pathway revealed that the type I IFN pathway was significantly enriched. Addition of a neutralizing type I IFN decoy receptor blocked the expression of IRF7 and IL-12p40 during DC infection, indicating the L. major\u2013induced expression of IL-12p40 is dependent upon the type I IFN signaling pathway. In stark contrast, IL-12p40 expression is not elicited by L. donovani, the etiological agent of deadly visceral leishmaniasis. Therefore, we examined the gene expression profile for several IFN response genes in L. major versus L. donovani DC infections. Our data revealed that L. major, but not L. donovani, induces expression of IRF2, IRF7, and IFIT5, implicating the regulation of type I IFN\u2013associated signaling pathways as mediating factors toward the production of IL-12.<\/jats:p>","DOI":"10.4049\/jimmunol.1203230","type":"journal-article","created":{"date-parts":[[2014,5,8]],"date-time":"2014-05-08T01:38:43Z","timestamp":1399513123000},"page":"5863-5872","source":"Crossref","is-referenced-by-count":34,"title":["Human Dendritic Cells Exhibit a Pronounced Type I IFN Signature following <i>Leishmania major<\/i> Infection That Is Required for IL-12 Induction"],"prefix":"10.1093","volume":"192","author":[{"given":"Michelle A","family":"Favila","sequence":"first","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas S","family":"Geraci","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erliang","family":"Zeng","sequence":"additional","affiliation":[{"name":"Genomics and Bioinformatics Core Facility, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brent","family":"Harker","sequence":"additional","affiliation":[{"name":"Genomics and Bioinformatics Core Facility, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Condon","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel N","family":"Cotton","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asha","family":"Jayakumar","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinita","family":"Tripathi","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary Ann","family":"McDowell","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, Eck Institute for Global Health, University of Notre Dame , Notre Dame, IN 46556"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2014,6,15]]},"reference":[{"key":"2025032404351279600_r1","doi-asserted-by":"crossref","first-page":"649","DOI":"10.1136\/pgmj.2006.047340corr1","article-title":"Leishmaniasis","volume":"83","author":"Piscopo","year":"2007","journal-title":"Postgrad.
