Listeria monocytogenes has a particular tropism for the central nervous system. To gain knowledge about the immune response elicited by L. monocytogenes in the brain, we used a rat ex-vivo organotypic nervous system culture as a model for Listeria infection. Brain sections were maintained severa... Read More
