ABSTRACT
Exosomes are small extracellular vesicles secreted by cells and have a major role in cell-to-cell signaling. As dengue infection progresses from a mild to a severe form of infection, the exosome's microRNA (miRNA) composition might change, which may contribute to pathogenesis. In this study, a comprehensive analysis of serum exosomal miRNAs was performed and their involvement in dengue virus-induced disease progression in an Indian cohort was assessed. Small RNA-seq showed 50 differentially expressed exosomal miRNAs that were significantly dysregulated during dengue infection. After extensive validation, miR-96-5p was found to be significantly upregulated, whereas miR-146a-5p was significantly downregulated with the progression of disease to severe form. Interestingly, a strong positive correlation was found between the expression levels of miR-96-5p and miR-146a-5p and the platelet levels of the patients. Further, study of miR-146a-5p showed that it regulates the expression of the proteins which are involved in the immune responses. These results suggest that miR-96-5p and miR-146a-5p could be used as diagnostic and prognostic markers for dengue disease progression, in addition to the already available biochemical and pathological parameters.
