The Role of Heterotypic DENV-specific CD8+ T Lymphocytes in an Immunocompetent Mouse Model of Secondary Dengue Virus Infection
Dengue is the most prevalent arthropod-borne viral disease worldwide and is caused by the four dengue virus serotypes (DENV-1-4). Sequential heterologous DENV infections can be associated with severe disease manifestations. Here, we present an immunocompetent mouse model of secondary DENV infection...

Sequential heterologous DENV infections can be associated with severe disease manifestations. Here, we present an immunocompetent mouse model of secondary DENV infection using non mouse-adapted DENV strains to investigate the pathogenesis of severe dengue disease.

Cross-reactive CD8+ T lymphocytes were found to be necessary and sufficient for signs of severe disease by adoptively transferring of DENV-1-immune CD8+ T lymphocytes before DENV-2 challenge. Disease signs were associated with production of tumor necrosis factor (TNF)-α and elevated cytotoxicity displayed by heterotypic anti-DENV-1 CD8+ T lymphocytes. These findings highlight the critical role of heterotypic anti-DENV CD8+ T lymphocytes in manifestations of severe dengue disease. © 2017 The Authors Fil:Talarico, L.B. Universidad de Buenos Aires.
