Alphaherpesvirus cell-to-cell spread through manipulation of the actin cytoskeleton by the viral
US3 protein kinase
Herman FAVOREEL – Ghent University (UGent)
Viruses are obligate intracellular parasites, only able to replicate inside a host cell. To be able
to reach and infect new host cells, viruses must exit a previously infected cell and travel
through the extracellular milieu to a new host cell. However, during passage in the
extracellular space, viral pathogens face hostile components of the immune system such as
neutralizing antibodies. Alternatively, some viruses have developed strategies to spread
directly from one cell to another (direct cell-to-cell spread), thereby avoiding the inhospitable
extracellular space.
We have discovered a new mode of such direct cell-to-cell spread by herpesviruses, which
constitute some of the most successfull and important viral pathogens worldwide. We have
found that the US3 protein kinase of herpesviruses forces the infected cell to remodel its actin
cytoskeleton, resulting in the formation of long cell projections. These cell projections contact
distant uninfected cells and firmly attach to these uninfected cells. Virus particles use these
cell projections as tunnels to efficiently reach and infect the contacted distant cells. Inside
these ‘tunnels’, the viruses are shielded from virus-neutralizing antibodies in the extracellular
milieu. We found that the US3 protein kinase triggers the actin changes and cell projections in
infected cells by activating cellular p21-activating kinases, which are key components of the
cellular signaling pathways that regulate the actin cytoskeleton. These findings shed new light
on the complex and fascinating interaction of herpesviruses with host cells and the immune
system, and identify novel potential targets for the development of antiviral strategies.

“Alphaherpesvirus cell-to-cell spread through manipulation of the actin cytoskeleton by the
viral US3 protein kinase”
Herman FAVOREEL – Ghent University (UGent)
Viruses are obligate intracellular parasites. In other words, upon infection of a host, they can
only replicate inside a cell of this host since they need the enzymatic machinery and building
blocks of a host cell for their own replication. Once replication is completed, often with the
production of hundreds or thousands of new virus particles, viruses will leave the infected cell
and infect a new cell to start another replication cycle.
In order to reach a new host cell, viruses must travel some time through the extracellular
milieu. During this passage in the extracellular space, the virus is vulnerable, and may be
intercepted and/or destroyed by components of the antiviral immune system of the host,
including virus-neutralizing antibodies.
Hence, it may come as no surprize that many of the most successfull viruses have developed
alternative modes of transmission from an infected to an uninfected cell. These consist of
direct cell-to-cell spread, thereby limiting or avoiding passage through the inhospitable
extracellular space.
Herpesviruses indisputably belong to the most successfull viral pathogens worldwide. They
most likely have been around for millions of years, co-evolving with their hosts along the way.
This has allowed each of the herpesviruses to establish lifelong dormant infections in their host.
Specific stimuli may reactivate these dormant herpesviruses, leading to lifelong periods of
recurrent symptoms and transmission to new hosts. A typical herpesvirus in humans is the
herpes simplex virus, causing recurrent oral and genital lesions. Recurrent reactivation and
disease caused by herpesviruses showcases the ability of these pathogens to circumvent
efficient elimination by the immune system of the host, including virus-neutralizing antibodies.
Identifying the strategies employed by herpesviruses to avoid elimination by the immune
system is pivotal, not only in gaining fundamental insights in the biology of these important
and highly successfull viruses, but also to design new antiviral strategies and vaccines.
We have discovered an entirely novel mode of herpesvirus direct cell-to-cell spread from an
infected to an uninfected cell. We have found that a viral protein, the US3 protein kinase,
forces the infected host cell to reorganize its actin cytoskeleton. The actin cytoskeleton
constitutes a fundamental aspect of the ‘skeleton’ of a cell, and changes in the actin
cytoskeleton may therefore drive substantial changes in the shape and behaviour of a cell.
We have found that these virus-induced changes in the actin cytoskeleton result in the
formation of very long cell projections. These cell projections make contact with other, distant
cells, and firmly attach to these cells. Video microscopy of fluorescently labeled viruses
showed that the viruses use these cell projections as a kind of tunnel. They rapidly migrate
inside the projections, followed by transmission into the contacted, previously uninfected host
cells. Addition of virus-neutralizing antibodies could not prevent this mode of spread,
indicating that using these cellular ‘tunnels’, the virus does not expose itself to the virusneutralizing antibodies in the extracellular milieu. We have demonstrated that the US3 protein
of herpesviruses induces these actin and cell shape changes by phosphorylating and thereby
activating p21-activated kinases, which are central components in the cellular signaling
pathways that regulate the actin cytoskeleton.

These findings create new insights in the complex and fascinating interactions between
herpesviruses and their host cells, and open up new avenues in the design of antiviral
strategies, by targeting the viral proteins responsible for triggering these events (i.e. the US3
protein kinase) and/or the cellular proteins that drive the resulting actin and cell shape
changes (i.e. p21-activated kinases).
