Impact of Nanoparticulates from Traffic Emissions on Viral Lung Infection


Nanoparticle exposure reactivates latent herpesvirus and restores a signature of acute infection (19 page pdf, Christine Sattler, Franco Moritz, Shanze Chen, Beatrix Steer, David Kutschke, Martin Irmler, Johannes Beckers, Oliver Eickelberg, Philippe Schmitt-Kopplin, Heiko Adler and Tobias Stoeger, Particle and Fibre Toxicology, Jan. 10, 2017)

Today we review a lab experiment on cells in mice that examined the impact of exposure to nanoparticles (NP). Results indicate that these nanoparticles can “reawaken” latent herpes viruses in the lung by weakening the immune system and allowing viruses to invade the host cell. The researchers would like to examine if these results can be transferred to humans and if so, if exposure to emissions from combustion and traffic-related emissions suggest another serious impact.
