3. Achilles heel: Bacterial pathogens often depend on pili for their attachment to host tissues. Researchers are looking for new drug candidates that can interfere with the complex self-assembly of these protein fibres at a specialised pore complex (usher) in the outer membrane (OM). Chaperones in the periplasm (P) protect the individual building blocks from aggregation. (Adapted from Remaut et al. (2008), Cell 133, )
