Chemokine receptor interactions with virus-like particles

Research output: Chapter in Book/Report/Conference proceedingChapter


Virus-like particles (VLPs) presenting conformational envelope proteins on their surface represent an invaluable tool to study molecular interactions between viruses and cellular receptors/co-receptors, eliminating biological risks associated with working with live native viruses. The availability of target cells expressing speci fi c chemokine receptors facilitates the dissection of speci fi c interactions between humanimmunodeficiency virus (HIV) viral envelope proteins and these receptors in the laboratory. Here, we describe a method to evaluate HIV-VLP binding to cellular chemokine co-receptors, by carboxy fluorescein succinimidyl ester labeling and cellular uptake.
