1. Effects of invasin and YopH of Yersinia pseudotuberculosis on host cell signaling
Abstract : Integrins are a large family of membrane-spanning heterodimeric (αβ) receptors that bind to ligands on other cells or to extracellular matrix (ECM) proteins. These receptors mediate bidirectional signaling over the cell membrane to induce signaling cascades mediating functions as cell adhesion, spreading and migration. READ MORE

2. Controlling virulence in Yersinia pseudotuberculosis through accumulation of phosphorylated CpxR
Abstract : Like many Gram-negative bacteria, the food-borne pathogen Yersinia pseudotuberculosis harbours different regulatory mechanisms to maintain an intact bacterial envelope especially during exposure to extracytoplasmic stress (ECS). The CpxA-CpxR two component regulatory system is one such ECS-responsive regulatory mechanism. READ MORE

4. Inhibition of phagocyte signaling by the Yersinia virulence protein YopH
Abstract : Yersinia pseudotuberculosis evades the immediate immune defense of a host organism by inhibiting bactericidal functions of phagocytes, including phagocytosis, cytokine release, and the oxidative burst. Consequently, this pathogen can survive and multiply in lymphatic tissues. An ensemble of proteins called Yops are involved in the virulence of Y. READ MORE

5. Perturbation of the epithelial barrier by enteric pathogens
Abstract : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. READ MORE
