A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial ‘nanodrills’ assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells’ outer membranes. The research supports the development of new drugs that target this mechanism, which is implicated in serious diseases. The discovery supports the development of new drugs that can target bacterial nanodrills and helps in treating the diseases in which they are implicated. These include pneumonia, meningitis and septicaemia. Extensive research into such drugs that is ongoing at the University of Leicester, which also provided a genetically modified form of the toxin to help identify the different steps in the hole-drilling process.
