The presence of antidengue virus antibodies in the serum of individuals prior to dengue virus infection is believed to be an important risk factor for severe dengue virus disease as a result of the phenomenon of antibody-dependent enhancement operating on Fc receptor (FcR)-bearing cells. In addition to blood monocytes, mast cells are susceptible to antibody-enhanced dengue virus infection, producing a number of inflammatory mediators including IL-1, IL-6, and CCL5. Using the human mast cell-like lines KU812 and HMC-1 as well as primary cultures of human cord blood-derived mast cells (CBMC), we aimed to identify the participating FcRs in antibody-enhanced mast cell dengue virus infection, as FcRs represent a potential site for therapeutic intervention. CBMC expressed significant levels of Fc\u03b3RI, Fc\u03b3RII, and Fc\u03b3RIII, and mast cell-like HMC-1 and KU812 cells expressed predominantly Fc\u03b3RII. All four serotypes of dengue virus showed antibody-enhanced binding to KU812 cells. Specific Fc\u03b3RII blockade with mAb IV.3 was found to significantly abrogate dengue virus binding to KU812 cells and CBMC in the presence of dengue-specific antibody. Dengue virus infection and the production of CCL5 by KU812 cells were also inhibited by Fc\u03b3RII blockade.<\/jats:p>","DOI":"10.1189\/jlb.0805441","type":"journal-article","created":{"date-parts":[[2006,8,30]],"date-time":"2006-08-30T08:21:54Z","timestamp":1156926114000},"page":"1242-1250","source":"Crossref","is-referenced-by-count":57,"title":["A dominant role for Fc\u03b3RII in antibody-enhanced dengue virus infection of human mast cells and associated CCL5 release"],"prefix":"10.1093","volume":"80","author":[{"given":"Michael G","family":"Brown","sequence":"first","affiliation":[{"name":"Department of Microbiology and Immunology and Dalhousie University , Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine A","family":"King","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology and Dalhousie University , Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine","family":"Sherren","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology and Dalhousie University , Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean S","family":"Marshall","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology and Dalhousie University , Halifax, Nova Scotia, Canada"},{"name":"Department of Pathology, Dalhousie University , Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Anderson","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology and Dalhousie University , Halifax, Nova Scotia, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2006,8,29]]},"reference":[{"key":"2023033007481943400_jlb1242-cit-B1","first-page":"276","article-title":"Observations related to the pathogenesis of dengue hemorrhagic fever.
