Epidemiologic and observational studies demonstrate that the majority of severe dengue cases, dengue hemorrhagic fever and dengue shock syndrome (DHF/DSS), occurs predominantly in either individuals with cross-reactive immunity following a secondary heterologous infection or in infants with primary DENV infections born from dengue-immune mothers, suggesting that B-cell-mediated and antibody responses impact on disease evolution. We demonstrate here that B cells play a pivotal role in host responses against primary DENV infection in mice. After infection, μMT(-/-) mice showed increased viral loads followed by severe disease manifestation characterized by intense thrombocytopenia, hemoconcentration, cytokine production and massive liver damage that culminated in death. In addition, we show that poly and monoclonal anti-DENV-specific antibodies can sufficiently increase viral replication through a suppression of early innate antiviral responses and enhance disease manifestation, so that a mostly non-lethal illness becomes a fatal disease resembling human DHF/DSS. Finally, treatment with intravenous immunoglobulin containing anti-DENV antibodies confirmed the potential enhancing capacity of subneutralizing antibodies to mediate virus infection and replication and induce severe disease manifestation of DENV-infected mice. Thus, our results show that humoral responses unleashed during DENV infections can exert protective or pathological outcomes and provide insight into the pathogenesis of this important human pathogen. 000284095 536__ $$0G:(DE-HGF)POF4-899$$a899 - ohne Topic (POF4-899)$$cPOF4-899$$fPOF IV$$x0 000284095 588__ $$aDataset connected to DataCite 000284095 650_7 $$2NLM Chemicals$$aCytokines 000284095 650_2 $$2MeSH$$aAnimals 000284095 650_2 $$2MeSH$$aAntibody-Dependent Enhancement 000284095 650_2 $$2MeSH$$aB-Lymphocytes: immunology 000284095 650_2 $$2MeSH$$aCytokines: blood 000284095 650_2 $$2MeSH$$aDeath 000284095 650_2 $$2MeSH$$aDengue: immunology 000284095 650_2 $$2MeSH$$aDengue: pathology 000284095 650_2 $$2MeSH$$aDengue Virus: immunology 000284095 650_2 $$2MeSH$$aImmunity, Innate 000284095 650_2 $$2MeSH$$aLiver: pathology 000284095 650_2 $$2MeSH$$aMice, Inbred C57BL 000284095 650_2 $$2MeSH$$aMice, Knockout 000284095 650_2 $$2MeSH$$aThrombocytopenia 000284095 650_2 $$2MeSH$$aViral Load 000284095 7001_ $$aFagundes, Caio T.$$b1 000284095 7001_ $$aValadão, Deborah F.$$b2 000284095 7001_ $$aÁvila, Thiago V.$$b3 000284095 7001_ $$aCisalpino, Daniel$$b4 000284095 7001_ $$aRocha, Rebeca F.$$b5 000284095 7001_ $$0P:(DE-2719)9001782$$aSecchim Ribeiro, Lucas$$b6$$udzne 000284095 7001_ $$aAscenção, Fernando R.$$b7 000284095 7001_ $$aKangussu, Lucas M.$$b8 000284095 7001_ $$aJunior, Celso M.
