Abstract
This research aims to position EVs as a versatile platform for vaccination and drug delivery. By studying their role in Kp infections, the findings could contribute to innovative therapeutic approaches, offering a groundbreaking strategy for preventing and treating MDR bacterial infections.
Macrophage-derived EVs function dually as (1) a protective, cell-free vaccine that primes immunity against Kp and (2) a biocompatible, low-immunogenicity delivery platform for enhancing antibiotic efficacy against intracellular pathogens. Our findings demonstrate that macrophage-derived EVs elicit protective immune responses against Kp infection, highlighting their potential as a novel EVs-based vaccination strategy against systemic bacterial challenges. By leveraging the immunomodulatory properties of EVs which shuttle host-derived immunostimulatory molecules and pathogen antigens I propose that EVs based platforms can precisely modulate host immunity to enhance pathogen clearance. Furthermore, EVs represent a safe and effective drug delivery system for combating bacterial infections, particularly those caused by MDR pathogens. Their biocompatibility, low toxicity, and ability to bypass traditional resistance mechanisms position them as a promising therapeutic alternative in the post-antibiotic era.
This study underscores the dual utility of EVs as both prophylactic vaccines and targeted antimicrobial delivery vehicles, offering a scalable solution to the growing threat of MDR infections.
