ABSTRACT
The expansion of the geographic footprint of dengue viruses (DENVs) and their mosquito vectors have affected more than half of the global population, including older adults who appear to show elevated risk of severe dengue. Despite this epidemiological trend, how age and senescence impact virus-host interactions involved in dengue pathogenesis to increase the risk of severe dengue is poorly understood. Herein, we show that conversion of diploid cells with finite lifespan into iPSCs followed by differentiation back into cell strain can be an approach to derive genetically identical cells at different stages of senescence to study virus and aging host interactions. Our findings show that cellular senescence impact the host response to infection and the ensuing outcome. We suggest iPSC-derive cell strains as a potentially useful technical approach to genetically controlled host-virus interaction studies to understand how aging impact viral pathogenesis.
