项目摘要
Project Summary
New experimental models are needed to develop treatments for varicella zoster virus (VZV), a
DNA virus that has infected over 90% of individuals worldwide. Primary infection causes chickenpox,
while reactivation of the virus within the nervous system can have dire consequences. Shingles
(herpes zoster) is the most common manifestation of viral reactivation, affecting one out of every
three people in the U.S. and causing post-herpetic neuralgia (PHN), a severe, often chronic, pain
syndrome with annual U.S. costs of over $1 billion. Viral reactivation within the central nervous
system can result in encephalitis and myelitis, often leading to death or severe cognitive and physical
disability. Notably, VZV continues to exact a marked toll despite the advent and widespread use of
antiviral agents (acyclovir) and vaccination, which only afford partial protection and do not specifically
address PHN. Thus, new therapies are needed to limit the morbidity and mortality associated with
neuronal infection and reactivation.
The major limitation in the study of VZV infection is the strict species-specificity of the virus,
such that it essentially exclusively infects human cells. As a result, there are no robust animal models
that recapitulate essential features of human disease. Moreover, the virus appears to utilize distinct
cellular and molecular pathways in different cell types. Thus, studies of viral infection in human
fibroblasts or other skin cells may not directly bear on pathogenesis within human neurons. Recently,
VZV has been shown to infect neurons derived from human neural stem cells and human pluripotent
stem cells, suggesting that stem-cell based approaches for the study of VZV pathogenesis are likely
to hold great promise for the development of new treatments. However, most human neuronal
cultures systems derived from stem cells are typically comprised of few, if any, sensory neurons.
This is a great limitation since sensory neurons are the main cell type in which the virus establishes
latency and later re-emerges during reactivation.
Here, we propose to develop a model of human pluripotent stem cell based model of sensory
neuron infection by VZV. The establishment of such a model will result in the ability to study VZV
neuropathogenesis in a relevant cell type. We anticipate that establishment of our model will yield
initial insights into how VZV infects and reactivates in human sensory neurons and will serve as the
basis for a system to develop new treatments for VZV reactivation and PHN.
