The importance of peroxisomes in the context of viral infections has been increasingly demonstrated in recent years. The discovery that MAVS localizes at peroxisomes and that peroxisomal and mitochondrial MAVS perform complementing functions within the antiviral response has raised the interest in studying the peroxisome-dependent signaling in the context of infection by different viruses. To that end, specific experimental procedures should be applied, taking into consideration the endogenous localization of MAVS at both organelles. The analysis of peroxisomal MAVS activation requires, hence, the preliminar generation and validation of cell lines where MAVS localizes solely at peroxisomes, as well as other specific cellular tools. Here, we present a detailed protocol to analyse the peroxisome-dependent antiviral response, using virus-specific and virus-unspecific stimuli.
