Peroxisomes and Viruses: Overview on Current Knowledge and Experimental Approaches.

The general interest in the study of the interplay between peroxisomes and viruses has increased in recent years, with different reports demonstrating that distinct viruses modulate peroxisome-related mechanisms to either counteract the cellular antiviral response or support viral propagation. Nevertheless, mechanistical details are still scarce, and information is often incomplete. In this chapter, we present an overview of the current knowledge concerning the interplay between peroxisomes and different viruses. We furthermore present, compare, and discuss the most relevant experimental approaches and tools used in the different studies. Finally, we stress the importance of further, more detailed, and spatial-temporal analyses that encompass all the different phases of the viruses' infection cycles. These studies may lead to the discovery of novel peroxisome-related cellular mechanisms that can further be explored as targets for the development of novel antiviral therapies.
