To investigate the role of human LCs in innate immune responses, we examined TLR expression and function of LC-like DCs derived from CD34+ progenitor cells and compared them to DCs derived from peripheral blood monocytes (monocyte-derived DC; Mo-DC). LC-like DCs and Mo-DCs expressed TLR1\u201310 mRNAs at comparable levels. Although many of the TLR-induced cytokine patterns were similar between the two cell types, stimulation with the TLR3 agonist poly(I:C) triggered significantly higher amounts of the IFN-inducible chemokines CXCL9 (monokine induced by IFN-\u03b3) and CXCL11 (IFN-\u03b3-inducible T cell \u03b1 chemoattractant) in LC-like DCs as compared with Mo-DCs. Supernatants from TLR3-activated LC-like DCs reduced intracellular replication of vesicular stomatitis virus in a type I IFN-dependent manner. Finally, CXCL9 colocalized with LCs in skin biopsy specimens from viral infections. Together, our data suggest that LCs exhibit a direct antiviral activity that is dependent on type I IFN as part of the innate immune system.<\/jats:p>","DOI":"10.4049\/jimmunol.177.1.298","type":"journal-article","created":{"date-parts":[[2014,4,18]],"date-time":"2014-04-18T19:47:14Z","timestamp":1397850434000},"page":"298-305","source":"Crossref","is-referenced-by-count":105,"title":["TLR Activation of Langerhans Cell-Like Dendritic Cells Triggers an Antiviral Immune Response"],"prefix":"10.1093","volume":"177","author":[{"given":"Claudia N","family":"Renn","sequence":"first","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David Jesse","family":"Sanchez","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Teresa","family":"Ochoa","sequence":"additional","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annaliza J","family":"Legaspi","sequence":"additional","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang-Keun","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Dermatology, College of Medicine, Pusan National University Hospital , Pusan ,","place":["Korea"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip T","family":"Liu","sequence":"additional","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan R","family":"Krutzik","sequence":"additional","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter A","family":"Sieling","sequence":"additional","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Genhong","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert L","family":"Modlin","sequence":"additional","affiliation":[{"name":"Division of Dermatology, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"},{"name":"Department of Microbiology, Immunology and Molecular Genetics, David Geffen School of Medicine at University of California, Los Angles (UCLA) , Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2006,7,1]]},"reference":[{"key":"2026020210143319800_R1","first-page":"245","volume-title":"Nature","year":"1998"},{"key":"2026020210143319800_R2","first-page":"248","volume-title":"Nature","year":"1977"},{"key":"2026020210143319800_R3","first-page":"247","volume-title":"Nature","year":"1977"},{"key":"2026020210143319800_R4","first-page":"973","volume-title":"Cell","year":"1996"},{"key":"2026020210143319800_R5","first-page":"104","volume-title":"Curr.
