Invading an Intestinal Mucosal Epithelial Cell Salmonella adheres to the microvilli of intestinal mucosal epithelial cells.
Salmonella invasins trigger actin polymerization and depolymerization.
This causes the epithelial cell to form pseudopods that engulf the Salmonella and place it in an endocytic vacuole. The Salmonella replicate within the endocytic vacuole and are subsequently released from the cell.
