Description We reported previously that natural killer (NK)
cell-mediated lysis of cytomegalovirus-infected targets
requires the presenceo f HLA-DR+ nonadherent
peripheral blood mononuclearc ells (NPBMC). In the
present study we determined whether NK cell-mediated
lysis of other herpesvirus-infected targets
also requires HLA-DR+ cells. Depletion of either
cluster designation (CD)16+ NK cells or HLA-DR+
cells from NPBMC significantly reduced their ability
to lyse herpes simplex virus (HSV)- and varicellazoster
virus (VZV)-infected fibroblasts. When CD16-
and HLA-DR- populations were mixedl,y sis of both
HSV- and VZV-infected targets was virtually completely
restored, indicating thaNt K cells and HLADR+
cells were required for lysis to occur. Cell-free
supernatants, obtained by incubating NPBMC or
CD16- cells with HSV- or VZV-infected targets, contained
antiviral activity and stimulated HLA-DRcells
to mediate lysis of corresponding virus-infected
targets. The addition of anti-interferon-a to
supernatants abolished their ability to stimulate
lysis. Thus, secretion of interferon-a by HLA-DR+
cells contributes to NK cell-mediated lysis of herpesvirus-
infected targets
