From: P-selectin glycoprotein ligand-1 (PSGL-1/CD162) is incorporated into clinical HIV-1 isolates and can mediate virus capture and subsequent transfer to permissive cells

PSGL-1 positive virions can be captured by P-selectin and transferred to HIV-permissive target cells for infection. A Schematic depicting the experimental workfolw: virus preparations were added to MadCAM-1 and/or P-selectin coated wells to allow for virion capture. Post-incubation, wells were washed extensively to remove unbound virus and then were either assayed for the amount of captured virus using p24 detection (top workflow), or TZM-bl cells were overlayed onto each well for virus transfer, ad infectivity measurements via luminescence readout (bottom workflow). B Experimental results from viruses produced through transfection of HEK293T, C infection of T cell lines, and D PBMC IIIB viruses in plate-based virus capture (left column) and transfer assays (right column). Results displayed are the mean ± SD of two experiments with samples tested in duplicate wells for B and C. P values were determined using an unpaired t test (*P < 0.05; ***P < 0.0001). Results shown in D are representative of two independent experiments tested with duplicate wells
