Abstract:
The discovery of 'molecular syringes' in several important gastrointestinal pathogens including Escherichia coli, Salmonella, Shigella and Yersinia, together with a better understanding of M cells and the mucosal immune system, has advanced our appreciation of multistage microorganism-host cell interactions. Recent studies suggest that these molecular strategies could be adapted for the development of modular mucosal vaccines.
Insights
Pathogenic bacteria use "molecular syringes" to interact with host cells. This discovery, along with insights into M cells and mucosal immunity, may enable the development of new modular mucosal vaccines.
