铜绿假单胞菌是一种机会性病原体,可引起严重的细胞损伤并破坏免疫反应以促进其存活。在铜绿假单胞菌众多的毒力因子中,III型分泌系统(T3SS)参与宿主细胞致病性。使用针状结构,T3SS检测真核细胞并将毒素直接注射到其细胞质中,从而突出其干扰宿主免疫反应的能力。在这篇综述中,我们讨论了T3SS和由该途径分泌的细菌效应物不仅激活免疫反应,而且可以操纵免疫反应促进铜绿假单胞菌感染的建立。
Pseudomonas aeruginosa is an opportunistic pathogen that can cause critical cellular damage and subvert the immune response to promote its survival. Among the numerous virulence factors of P. aeruginosa, the type III secretion system (T3SS) is involved in host cell pathogenicity. Using a needle-like structure, T3SS detects eukaryotic cells and injects toxins directly into their cytosol, thus highlighting its ability to interfere with the host immune response. In this mini-review, we discuss how the T3SS and bacterial effectors secreted by this pathway not only activate the immune response but can also manipulate it to promote the establishment of P. aeruginosa infections.
