Identification of pelo, a host gene needed for efficient virus production

Viruses have limited genetic and , and often depend on hijacking resources (for example, nutrients and basic cellular machinery) from their hosts to survive, multiply, and cause disease. , from in China, and colleagues conducted a systematic search in the fruit fly Drosophila for genes of the fly host that contribute to high-speed synthesis of viral proteins, and identified the pelo gene as a critical host factor.

pelo is necessary for the efficient manufacturing of the capsid proteins of a number of fly viruses. As the protein dos not seem to fulfil an essential function in the host and is conserved across species, pelo might be a broad-spectrum antiviral target. The scientists conclude “the discovery of the general antiviral activity by pelo deficiency may provide a new therapeutic target for broad-spectrum antiviral therapy”.
