A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Upon epithelial cell contact, Shigella type III effectors activate complex signaling pathways that induce localized membrane ruffling, resulting in Shigella invasion. Bacterial induced membrane ruffles require a timely coordination of cytoskeletal processes, including actin polymerization, filament reorganization and depolymerization, orchestrated by Rho GTPases and tyrosine kinases. An emerging concept is that multiple Shigella effectors act in synergy to promote actin polymerization in membrane extensions at the site of bacterial entry. Recent advances point to the role of Abl/Arg and Src tyrosine kinases as key regulators of bacterial induced cytoskeletal dynamics.
