Characterization of hepatitis C virus interaction with heparan sulfate proteoglycans.
UNLABELLED Hepatitis C virus (HCV) entry involves binding to cell surface heparan sulfate (HS) structures. However, due to the lipoprotein-like structure of HCV, the exact contribution of virion components to this interaction remains controversial. Here, we investigated the relative contribution of HCV envelope proteins and apolipoprotein E in the HS-binding step. Deletion of hypervariable regi...
متن کاملCharacterization of pseudorabies virus glycoprotein C attachment to heparan sulfate proteoglycans.
Pseudorabies virus first attaches to cells through an interaction between the envelope glycoprotein C (gC) and the cell surface heparan sulfate (HS) that is linked to proteoglycans (HSPGs). The HS-binding domain of gC is composed of three discrete heparin-binding domains (HBDs), designated HBD1, -2 and -3 for their proximity to the amino terminus of gC. Each HBD can independently mediate virus ...
متن کاملHeparan sulfate proteoglycans.
Heparan sulfate proteoglycans are found at the cell surface and in the extracellular matrix, where they interact with a plethora of ligands. Over the last decade, new insights have emerged regarding the mechanism and biological significance of these interactions. Here, we discuss changing views on the specificity of protein-heparan sulfate binding and the activity of HSPGs as receptors and core...
متن کاملHeparan sulfate proteoglycans
Studies of the involvement of ECM molecules in cell attachment, growth, and differentiation have revealed a central role of heparan sulfate (HS) proteoglycans (HSPGs) in early embryogenesis, morphogenesis, angiogenesis, and epithelial-mesenchymal interactions (1–3). HS chains bind a multitude of proteins and ensure that a wide variety of bioactive molecules (e.g., heparin-binding growth factors...
متن کاملHeparan Sulfate Proteoglycans in Infection
To cause infections, microbial pathogens elaborate a multitude of factors that interact with host components. Using these host–pathogen interactions to their advantage, pathogens attach, invade, disseminate, and evade host defense mechanisms to promote their survival in the hostile host environment. Many viruses, bacteria, and parasites express adhesins that bind to cell surface heparan sulfate...
