Varicella zoster virus productively infects human natural killer cells and manipulates phenotype

Fig 3

NK cells are productively infected by VZV and support virus transmission.

NK cells (CD3CD56+) were FACS sorted from healthy human donor CD56+-selected lymphocytes following mock or VZV infection for 1 day. (A & B) Staining by IFA of sorted VZV cultured (left panels) or mock cultured (right panels) NK cells for IE63 (A), pORF29 (B) or respective isotype control, with DAPI (n = 3). (C) Sorted VZV cultured NK cells were added to ARPE-19 epithelial cell monolayers. Four days later monolayers were fixed and infectious centres detected with IFA by staining for IE63 and gE:gI, with DAPI. One representative experiment of five is shown.
