Figure 1
A paradigm of "zippering" entry of a bacterial pathogen into epithelial cells. Invasin mediated binding of Yersinia pseudotuberculosis to ß1 integrins and internalisation.
Figure 2
A paradigm or "triggering" entry of pathogens into epithelial cells: TTSS mediated translocation of Salmonella and Shigella effectors of entry inducing the formation of a macropinocytic vacuole.
Figure 3
Structure of the TTSS of Shigella flexneri. OM, outer membrane; PS, periplasmic space; IM, inner membrane; Cyt, cytoplasm.
