Gene editing tool-loaded biomimetic cationic vesicles with highly efficient bacterial internalization for in vivo eradication of pathogens

Abstract In the post-COVID-19 era, drug-resistant bacterial infections emerge as one of major death causes, where multidrug-resistant Acinetobacter baumannii (MRAB) and drug-resistant Pseudomonas aeruginosa (DRPA) represent primary pathogens. However, the classical antibiotic strategy currently face...

description Abstract In the post-COVID-19 era, drug-resistant bacterial infections emerge as one of major death causes, where multidrug-resistant Acinetobacter baumannii (MRAB) and drug-resistant Pseudomonas aeruginosa (DRPA) represent primary pathogens. However, the classical antibiotic strategy currently faces the bottleneck of drug resistance. We develop an antimicrobial strategy that applies the selective delivery of CRISPR/Cas9 plasmids to pathogens with biomimetic cationic hybrid vesicles (BCVs), irrelevant to bacterial drug resistance. CRISPR/Cas9 plasmids were constructed, replicating in MRAB or DRPA and expressing ribonucleic proteins, leading to irreparable chromosomal lesions; however, delivering the negatively charged plasmids with extremely large molecular weight to the pathogens at the infection site became a huge challenge. We found that the BCVs integrating the bacterial out membrane vesicles and cationic lipids efficiently delivered the plasmids in vitro/in vivo to the pathogens followed by effective internalization. The BCVs were used by intratracheal or topical hydrogel application against MRAB pulmonary infection or DRPA wound infection, and both of the two pathogens were eradicated from the lung or the wound. CRISPR/Cas9 plasmid-loaded BCVs become a promising medication for drug-resistant bacteria infections.
