Like varicella-zoster virus (VZV), simian varicella virus (SVV) reactivates to
produce zoster. In the present study, 5 rhesus macaques were inoculated
intrabronchially with SVV, and 5 months later, 4 monkeys were immunosuppressed; 1
monkey was not immunosuppressed but was subjected to the stress of
transportation. In 4 monkeys, a zoster rash developed 7 to 12 weeks after
immunosuppression, and a rash also developed in the monkey that was not
immunosuppressed. Analysis at 24 to 48 h after zoster revealed SVV antigen in the
lung alveolar wall, in ganglionic neurons and nonneuronal cells, and in skin and
in lymph nodes. In skin, SVV was found primarily in sweat glands. In lymph nodes,
the SVV antigen colocalized mostly with macrophages, dendritic cells, and, to a
lesser extent, T cells. The presence of SVV in lymph nodes, as verified by
quantitative PCR detection of SVV DNA, might reflect the sequestration of virus
by macrophages and dendritic cells in lymph nodes or the presentation of viral
antigens to T cells to initiate an immune response against SVV, or both.
IMPORTANCE: VZV causes varicella (chickenpox), becomes latent in ganglia, and
reactivates to produce zoster and multiple other serious neurological disorders.
SVV in nonhuman primates has proved to be a useful model in which the
pathogenesis of the virus parallels the pathogenesis of VZV in humans. Here, we
show that SVV antigens are present in sweat glands in skin and in macrophages and
dendritic cells in lymph nodes after SVV reactivation in monkeys, raising the
possibility that macrophages and dendritic cells in lymph nodes serve as
antigen-presenting cells to activate T cell responses against SVV after
reactivation.
