In Figure 5F, much more viable cells have been also observed inside the bacteria-infected cells following THSG therapy. Furthermore, experiments with annexin V and PI staining (Figure 5G,H) demonstrated that THSG (30, 100, and 200 ) also substantially decreased the percentage of apoptotic cells produced by P. gingivalis by about 50 . The percentage of apoptotic cells improved from 5 to 61 within the bacteria infection (Figure 5H). THSG at 30, 100, and 200 lowered the percentage of apoptotic cells in P. gingivalis-treated MBECs to 30 , 29 , and 36 (Figure 5H). Additionally, the number of condensed nuclei soon after P. gingivalis infection also decreased in major brain endothelial cells treated with THSG (Figure 5I). 3.6. THSG Protects MBECs from Bacteria-Stimulated Inflammation and Apoptosis by means of ROS/NF-B Signaling PathwayAs shown in Figure 6A,B, the intracellular ROS levels of MBECs in P. gingivalis infection improved from six to 53 . Furthermore, THSG remedy at 30, one hundred, and 200 decreased the ROS levels to 27 , 32 , and 38 , respectively. Furthermore, we additional observed that the ntioxidants 11, 0 11, x FOR PEER Assessment 2022, degradation of IB protein resulting from bacterial infection was enhanced in MBECs with THSG nts 2022, treatment (Figure 6C,D). THSG remedy also decreased the enhancement of NF-B p65 in nuclear proteins induced by P. gingivalis infection in MBECs (Figure 6C,E).12 ofFigure four. Cont.Antioxidants 2022, 11,13 ofFigure four.
