    Why doesn't HIV form plaques in any types of cells?

    I'm not sure that anyone has tried very hard to develop a plaque
    assay. The virus is cytopathic, yet the relevant cells for infection
    are lymphocytes, which don't adhere to plastic dishes. Therefore
    developing a plaque assay would not be straightforward.

    The researchers extracted white blood cells from all the subjects and exposed them to HIV in a culture dish. They reported in the journal BMC Immunology that HIV replication was slowed by about 80% in the cells from those who had received smallpox vaccination.
