Hypusination Orchestrates the Antimicrobial Response of Macrophages

Abstract

Gobert et al. demonstrate that hypusination, a specific mechanism regulating translation, is induced in macrophages by bacteria. Hypusination is required for the translation of inducible antimicrobial effectors. Mice that specifically lack hypusination in macrophages are highly susceptible to Helicobacter pylori and Citrobacter rodentium, two pathogens of the gastrointestinal tract.
