阳离子抗菌肽(CAMPs)是重要的先天性免疫防御物质,它们能抑制病原体的定植,并有助于清除感染。革兰氏阴性菌病原体是主要的作用靶点,但其中许多已进化出抵抗这些抗菌物质的机制。这些耐药机制可能是细菌致病性的关键因素,并且对于在宿主体内的生存往往至关重要。在此,我们总结了革兰氏阴性菌用来抵抗阳离子抗菌肽的方法。了解这些机制可能会为针对具有广泛阳离子抗菌肽耐药性的病原体制定新的治疗策略提供思路。
Cationic antimicrobial peptides (CAMPs) are important innate immune defenses that inhibit colonization by pathogens and contribute to clearance of infections. Gram-negative bacterial pathogens are a major target, yet many of them have evolved mechanisms to resist these antimicrobials. These resistance mechanisms can be critical contributors to bacterial virulence and are often crucial for survival within the host. Here, we summarize methods used by Gram-negative bacteria to resist CAMPs. Understanding these mechanisms may lead to new therapeutic strategies against pathogens with extensive CAMP resistance.
