Dengue virus NS1 undergoes partial nuclear translocation to modulate host transcription and support viral replication

The Takeaway
For decades, researchers thought the NS1 protein in Dengue just floated around the edges of your cells or in your bloodstream, but it turns out it’s actually a molecular spy. This study reveals that NS1 performs a 'secret mission' by entering the cell nucleus—the vault where your genetic code is kept—to hijack how your body reads its own blueprints. By messing with host transcription, the virus effectively stages a coup, forcing your own cells to prioritize making more virus over protecting you. This discovery is a game-changer because it identifies a specific, hidden vulnerability in how Dengue operates that we never knew existed. If we can block this protein from reaching the nucleus, we could potentially stop the infection before it even takes hold of the body.
From the abstract
The dengue virus (DENV) non-structural protein 1 (NS1) is a glycoprotein highly conserved among mosquito-borne orthoflaviviruses. NS1 is typically localized in the lumen of the endoplasmic reticulum, where it forms part of the replication complexes, and is also exposed at the plasma membrane. In addition, NS1 is secreted as a lipoprotein. Here, using a combination of approaches, including confocal microscopy with deconvolution, in situ analysis, and biochemical cell fractionation, we show that a
