Abstract

© 2016 John Wiley & Sons Ltd. A growing number of human diseases seem to be associated with protein misfolding and deposition into aggregates. Bednarska and colleagues exploit the cytotoxic nature of protein aggregates to target bacterial infections. Protein aggregation is at the same time generic and sequence dependent; this allowed the authors to develop novel aggregation-prone antimicrobial peptides that penetrate bacteria and induce a peptide specific proteostatic collapse that leads to fast bacterial death, without any observable effects on host cells. The applicability of this intriguing strategy was demonstrated by curing animal models from bacterial sepsis. Although the precise mechanisms underlying the bactericidal activity of the peptide aggregates are still not clear, there is no doubt that this approach offers an exciting therapeutic alternative to conventional antibiotics.
