title: Exploitation of host factors for efficient infection by Shigella.
abstract: Shigellosis is a worldwide endemic ulcerating disease of the large intestine caused by enteroinvasive bacteria. Shigella takes the route via M-cells and macrophages to access the basolateral pole of enterocytes. After invasion of and cell-to-cell spread within the epithelial cell layer, the bacterium multiplies within the cytoplasm of enterocytes. Induced by a limited number of bacterial effector proteins, Shigella makes use of established signaling pathways of the host cell to achieve internalization, transcytosis, apoptosis or cell-to-cell spread. This review addresses the host factors required for efficient infection focusing on Shigella-induced cytoskeletal rearrangements and associated signaling.
