Intracellular bacterial pathogens such as Listeria monocytogenes can change host cell transcription programs to promote infection. Eskandarian et al. found that during infection, the Listeria effector protein InlB promoted the movement of a host protein deacetylase, SIRT2, from its normal location in the cytosol to the nucleus. In the nucleus, SIRT2 helped to repress a number of host cell genes by deacetylating one of their associated histones. In mice, reduced levels of SIRT2 impaired bacterial infection.
