Designer protein pseudo-capsids targeting intracellular bacteria

This is the authors' abstract. We don't add key points for this paper.

The emergence of multidrug-resistant bacteria stimulates the search for antimicrobial materials capable of addressing challenges conventional antibiotics fail to address. The ability to target intracellular bacteria remains one of the most fundamental tasks for contemporary antimicrobial treatments. Here we report engineered protein pseudo-capsids targeting bacteria internalised in macrophages. Using a combination of live-cell imaging and single-cell electron microscopy analysis we show that these materials effectively disrupt the bacteria without affecting the host cells. The study offers a disruptive antimicrobial strategy demonstrating potential for developing principally more challenging mechanisms for bacteria to overcome.
