摘要 | Intracellular methicillin-resistant Staphylococcus aureus (MRSA) is extremely difficult to remove by common antibiotics, leading to infection recurrence and resistance. Herein we report a novel exosome-based antibiotic delivery platform for eradicating intracellular MRSA, where mannosylated exosome (MExos) is employed as the drug carrier and preferentially taken up by macrophages, delivering lysostaphin (MExoL) and vancomycin (MExoV) to intracellular pathogens. Combination of MExoL and MExoV eradicated intracellular quiescent MRSA. Moreover, MExos rapidly accumulated in mouse liver and spleen, the target organs of intracellular MRSA, after intravenous (IV) administration. Thus, the MExos antibiotic delivery platform is a promising strategy for combating intracellular infection. |
