Dengue viruses infect cells by attaching to a surface receptor which remains unknown. The putative receptor molecules of dengue virus type 2 on the surface of mosquito (AP-61) and mammalian (LLC-MK2) cell lines were investigated. The immunochemical detection and structural analysis of carbohydrates

BACKGROUND Dendritic cells (DC), present in the skin, are the first target cells of dengue virus (DENV). Dendritic cell-specific intercellular adhesion molecule 3-grabbing non-integrin (DC-SIGN) is present on DC and recognizes N-glycosylation sites on the E-glycoprotein of DENV. Thus, the

Antiviral activity of carbohydrate-binding agents and the role of DC-SIGN in dengue virus infection.

Dendritic cell-specific intercellular adhesion molecule 3-grabbing non-integrin (DC-SIGN) is an important binding receptor for dengue virus (DENV) that recognizes N-glycosylation sites on the viral E-glycoprotein. DENV cannot bind nor infect the human B-cell line Raji/0. However, DENV productively

Dengue virus (DENV), which is transmitted by Aedes mosquitoes, causes fever and hemorrhagic disorders in humans. The virus entry process mediated through host receptor molecule(s) is crucial for virus propagation and the pathological progression of dengue disease. Therefore, elucidation of the

Dengue virus (DENV) is a significant human pathogen that causes millions of infections and results in about 24,000 deaths each year. Dendritic cell-specific ICAM3 grabbing nonintegrin (DC-SIGN), abundant in immature dendritic cells, was previously reported as being an ancillary receptor interacting

Dengue virus (DENV) infection is a significant burden in Indonesia and other tropical countries. DENV infection has a wide spectrum of clinical manifestations, i.e. asymptomatic, dengue fever, dengue hemorrhagic fever and dengue shock syndrome. The variety of clinical manifestations may be due to

The envelope glycoproteins of dengue 1 and dengue 2 viruses grown in mosquito cells differ in their utilization of potential glycosylation sites.

We have previously isolated and characterized two dengue (DEN) 2 viruses mutant in their fusion-from-within (FFWI) phenotype in the insect cell line C6/36. Both viruses lost a potential glycosylation site (Asn-153) in the envelope (E) glycoprotein. To determine whether the change in FFWI phenotype

A series of 12 carbohydrate compounds were synthesized by introduction of a sulfated group at specific positions and evaluated for their activities against dengue virus (DENV) infection as well as binding to BHK-21 cells. 3-O-sulfated GlcA was active against DENV infection, whereas 2-O-sulfated GlcA
