Abstract: Pseudomonas aeruginosa belongs to the genus Pseudomonas and is a common Gram-negative, exclusively aerobic, conditionally pathogenic bacterium with the characteristics of easy colonization, mutation, and multidrug resistance (Deng et al., 2015; Azam and Khan, 2019; Jurado-Martín et al., 2021). It is mainly distributed in the air, soil, water, intestinal tract, and skin surface of humans and domestic animals and can cause complications such as ulcerative keratitis, otitis externa, skin and soft tissue infections, respiratory infections, sepsis, osteomyelitis, endocarditis, and urinary tract infections in burned or immunocompromised patients (Azam and Khan, 2019; Chai and Xu, 2020; Voth et al., 2020). P. aeruginosa is a naturally drug-resistant bacterium that is resistant to a wide range of antibiotics, making it one of the major opportunistic pathogens leading to in-hospital infections (Pang et al., 2019; Chai and Xu, 2020; Reynolds and Kollef, 2021). According to the surveillance report of the China Antimicrobial Resistance Surveillance System (CARSS, http://www.carss.cn), Gram-negative bacteria accounted for more than 70% of all bacterial infections, and P. aeruginosa accounted for 12.4%, 12.0%, and 12.2% in 2018, 2019, and 2020, respectively. Therefore, P. aeruginosa infection has become an important concern in public health care, and it is particularly important to gain insight into the means of host immune defense against P. aeruginosa infection.

摘要：随着铜绿假单胞菌（铜绿）的耐药性逐年增强，铜绿感染已经成为公共医疗卫生的重点关注问题。线粒体自噬及其介导的线粒体功能障碍在多种细菌感染中已被报道，但线粒体功能障碍在宿主调控铜绿感染中的作用尚不明确。因此，本研究建立铜绿刺激小鼠巨噬细胞感染模型和小鼠急性铜绿感染模型，探讨铜绿是否通过诱导线粒体自噬改变线粒体功能，进而影响宿主免疫炎症反应和细胞毒性，并通过监测生存率和肺组织病理学变化进一步确定线粒体自噬在小鼠铜绿体内感染模型中的作用。结果表明，铜绿引起小鼠腹腔巨噬细胞线粒体功能障碍，并通过线粒体自噬途径清除铜绿刺激引起的活性氧（ROS）累积，从而抑制铜绿引起的促炎性细胞因子分泌并增强细胞毒性。体内实验进一步确认线粒体自噬在铜绿体内感染中的作用。
