INTRODUCTION. Dengue virus (DV) belongs to the genus Flavivirus, a large group of emerging pathogens capable of causing severe human diseases.Among these, DV represents the most prevalent mosquito-borne human-pathogenic virus worldwide, comprising 4 serotypes that are transmitted mainly by infected Aedes mosquitoes during a blood meal.

Abstract. The antiviral mechanism of action of iminosugars against many enveloped viruses, including dengue virus (DENV), HIV, influenza and hepatitis C virus, is believed to be mediated by inducing misfolding of viral N-linked glycoproteins through inhibition of host endoplasmic reticulum-resident α-glucosidase enzymes.

This host alternation imposes a selective pressure on the viral population. Here, we found that dengue virus, the most important viral human pathogen transmitted by insects, evolved a mechanism to differentially regulate the production of viral non-coding RNAs in mosquitos and humans, with a significant impact on viral fitness in each host.

Jun 18, 2019 · Dengue fever is one of the most important mosquito-borne viral infections in large parts of tropical and subtropical countries and is a significant public health concern and socioeconomic burden. There is an urgent need to develop antivirals that can effectively reduce dengue virus (DENV) replication and decrease viral load.

A recent systematic review and meta-analysis showed that allergic symptoms are one of the core symptoms that are highly associated with dengue severity. Mechanism of infection. Dengue virus’ (DENV) E envelope protein binds to a cellular receptor. The exact nature of the cellular receptor has not been fully elucidated.

Sep 21, 2012 · Dengue virus enters host cells by interacting with cell surface receptors, e.g. C‐type lectins, followed by clathrin‐mediated endocytosis and trafficking into endosomes. Here, the virion delivers its genome into the host cytosol. The presence of dengue virus can be sensed by receptors on the cell surface, in the endosomes, or in the host cytosol.
SUMMARY Much remains to be learned about the pathogenesis of the different manifestations of dengue virus (DENV) infections in humans. They may range from subclinical infection to dengue fever, dengue hemorrhagic fever (DHF), and eventually dengue shock syndrome (DSS). As both cell tropism and tissue tropism of DENV are considered major determinants in the pathogenesis of dengue, there is a ...
Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.
