淋球菌和脑膜炎奈瑟氏菌是革兰氏阴性细菌病原体,非常适合在人体粘膜表面生长和在宿主之间有效传播。其中一个重要的致病因素是细菌和中性粒细胞之间的相互作用,中性粒细胞在感染期间被大量招募。尽管这种强烈的宿主反应可能只是反映了对细菌的有效免疫识别,但越来越多的证据表明,事实上,这些专属人类病原体操纵先天免疫反应,以促进感染过程。本文综述了致病性奈瑟氏菌抵抗和调节中性粒细胞抗菌活性的机制。它还详细说明了有关奈瑟菌-中性粒细胞关系的一些主要悬而未决的问题,并提出了这种关系对病原体的潜在好处。
Neisseria gonorrhoeae and Neisseria meningitidis are Gram-negative bacterial pathogens that are exquisitely adapted for growth at human mucosal surfaces and for efficient transmission between hosts. One factor that is essential to neisserial pathogenesis is the interaction between the bacteria and neutrophils, which are recruited in high numbers during infection. Although this vigorous host response could simply reflect effective immune recognition of the bacteria, there is mounting evidence that in fact these obligate human pathogens manipulate the innate immune response to promote infectious processes. This Review summarizes the mechanisms used by pathogenic neisseriae to resist and modulate the antimicrobial activities of neutrophils. It also details some of the major outstanding questions about the Neisseria–neutrophil relationship and proposes potential benefits of this relationship for the pathogen.
