| Description: |
Nonstructural protein 1 (NS1) of dengue virus (DENV) can influence dengue severity. In this study, we used RNA sequencing analysis to assess the blood monocyte response to different concentrations of NS1. We showed that NS1 at the level found in severe dengue may be involved in severe dengue development through 2 potential mechanisms: induction of excessive inflammation and suppression of antiviral responses. At high levels, NS1 significantly up-regulated S100A8 and S100A9, ACOD1, and TREM1, which might help amplify the inflammatory loops. In terms of antiviral suppression, we found that high NS1 concentration significantly suppressed interferon signaling and major histocompatibililty complex class II transcripts. This potentially delayed the clearance of both DENV and NS1 protein. Our study highlighted the possible role of NS1-activated monocytes in dengue severity. |
