General description

Dengue virus (DENV) is a mosquito-borne flavivirus and is one of the most common mosquito-transmitted viral infections. The DENV particle is about 500 nm in diameter and includes a positive-sense RNA genome with ~10,700 nucleotides and 3 structural proteins known as capsid (C), precursor membrane (prM), and envelope (E) proteins. In addition, the RNA genome of dengue virus also encodes seven nonstructural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B and NS5) that are shown to be essential for viral replication. DENV NS1, a 48-kDa glycoprotein (aa 776-1127 of genome polyprotein), is highly conserved among all flaviviruses and is essential for viral replication. It is expressed as a monomer in infected cells and after post-translational modification in the lumen of endoplasmic reticulum, it forms homodimers associated with organelle membranes and the cell membrane. NS1 is reported to be involved in immune evasion, pathogenesis, and viral replication. Once cleaved off the polyprotein, is targeted to three destinations: the viral replication cycle, the plasma membrane and the extracellular compartment. NS1 is secreted in a hexamer form, which is composed of three dimers with a detergent-sensitive hydrophobic central cavity and it plays a role against host immune response. NS1 is shown to induce expression of sialidases, heparanase, and activates cathepsin L, which activates heparinase via enzymatic cleavage. These effects are may contribute to the endothelial hyperpermeability commonly observed in severe dengue disease. During the recovery phase, NS1 is cleared from the circulation by antibody-mediated effects. Clone 323 displays reactivity to NS1 protein in all Dengue viruses (1-4).
