Listeria monocytogenes infection in macrophages induces vacuolar-dependent host miRNA response.

Listeria monocytogenes is a gram-positive facultative intracellular pathogen, causing serious illness in immunocompromised individuals and pregnant women. Upon detection by macrophages, which are key players of the innate immune response against infection, L. monocytogenes induces specific host cell responses which need to be tightly controlled at transcriptional and post-transcriptional levels.
