And even though the latter is thought to provide a more difficult challenge for neutralizing antibodies, most of the studies so far have examined the antibodies in the context of free virus infections. (sciencedaily.com)
In addition to such «virological synapses,» they also observed free virus particles that appear to have covered some distance between their «mother» cell and the cell that would become their target to infect. (sciencedaily.com)
Neutralization of free virus, but not cell - cell transmission, was linked with the activity of specific Nabs to inhibit prior to the binding of the virus to the CD4 receptor on T cells, highlighting the functional differences of the two processes. (sciencedaily.com)
