Abstract

Antimicrobial Resistance (AMR) raises a serious concern as it contributes to the global mortality by 5 million deaths per year. The overall impact pertaining to significant membrane changes, through broad spectrum drugs have rendered the bacteria resistant over the years. The economic expenditure due to increasing drug resistance poses a global burden on healthcare community and must be dealt with immediate effect. Nanoparticles (NP) have demonstrated inherent therapeutic potential or can serve as nanocarriers of antibiotics against multidrug resistant (MDR) pathogens. These carriers can mask the antibiotics and help evade the resistance mechanism of the bacteria. The targeted delivery can be fine-tuned through surface functionalization of Nanocarriers using aptamers, antibodies etc. This review covers various molecular mechanisms acquired by resistant bacteria towards membrane modification. Mechanistic insight on 'NP surface-bacterial membrane' interactions are crucial in deciding the role of NP as therapeutic. Finally, we highlight the potential accessible membrane targets for designing smart surface-functionalized nanocarriers which can act as bacteria-targeted robots over the existing clinically available antibiotics. As the bacterial strains around us continue to evolve into resistant versions, nanomedicine can offer promising and alternative tools in overcoming AMR.

摘要

抗菌耐药性(AMR)引发了严重关注,因为它每年导致全球500万人死亡。多年来,通过广谱药物引起的重大膜变化所产生的总体影响使细菌产生了耐药性。由于耐药性增加导致的经济支出给医疗界带来了全球负担,必须立即加以应对。纳米颗粒(NP)已显示出固有的治疗潜力,或可作为抗生素针对多重耐药(MDR)病原体的纳米载体。这些载体可以掩盖抗生素,帮助规避细菌的耐药机制。可以通过使用适配体、抗体等对纳米载体进行表面功能化来微调靶向递送。本综述涵盖了耐药细菌获得的各种针对膜修饰的分子机制。对“NP表面-细菌膜”相互作用的机理洞察对于确定NP作为治疗手段的作用至关重要。最后,我们强调了设计智能表面功能化纳米载体的潜在可及膜靶点,这些纳米载体可以作为优于现有临床可用抗生素的细菌靶向机器人。随着我们周围的细菌菌株不断演变成耐药版本,纳米医学可以提供有前景的替代工具来克服抗菌耐药性。
