Abstract

Abstract This study evaluated the anti-inflammation effect of the three main short-chain fatty acids (SCFAs) on Acinetobacter baumannii-induced THP-1 cells. The three main SCFAs could inhibit A. baumannii-stimulated THP-1 cell NF-κB pathway activity and the expressions of NLRP3 inflamma-some and GSDMD, and increase autophagy. The three main SCFAs, especially the sodium butyrate (NaB), had the effect of down-regulation of ROS and TLR-2 expression in THP-1 cells. NaB and sodium propionate (NaPc), but not sodium acetate (NaAc), dramatically suppressed IL-1β and IFN-γ expression. The results indicated that NaB and NaPc could significantly inhibit the inflammation of THP-1 cells induced by A. baumannii, and the inhibitory effect was in the order of NaB > NaPc > NaAC. NaB and NaPc may inhibit inflammation through TLR-2/NF-κB/ROS/NLRP3 signaling pathway.

NaB和NaPc通过TLR-2/NF-κB/ROS/NLRP3途径对鲍曼不动杆菌刺激的THP-1细胞的抗炎作用。

本研究评估了三种主要短链脂肪酸(SCFAs)对鲍曼不动杆菌诱导的THP-1细胞的抗炎作用。3种主要SCFAs均能抑制鲍曼杆菌刺激的THP-1细胞NF-κB通路活性、NLRP3炎性蛋白和GSDMD的表达，增加自噬。三种主要SCFAs，尤其是丁酸钠(NaB)，在THP-1细胞中具有下调ROS和TLR-2表达的作用。NaB和丙酸钠(NaPc)显著抑制IL-1β和IFN-γ的表达，而乙酸钠(NaAc)不显著。结果表明，NaB和NaPc均能显著抑制鲍曼单胞菌诱导的THP-1细胞的炎症反应，且抑制作用顺序为NaB > NaPc > NaAC。NaB和NaPc可能通过TLR-2/NF-κB/ROS/NLRP3信号通路抑制炎症。
