doi: 10.2147/JIR.S593405

Figure Lengend Snippet: Proposed mechanism linking decreased postoperative serum Klotho levels to postoperative cognitive dysfunction (POCD) after abdominal surgery. Surgery and prolonged anesthesia lead to a reduction in serum Klotho levels, which contributes to increased oxidative stress and systemic inflammation, as indicated by elevated levels of CRP, IL-1β, and IL-6. These processes promote neuroinflammation and synaptic dysfunction, resulting in cognitive decline and POCD. Arrows indicate the direction of the effects, illustrating how decreased Klotho mediates the relationship between perioperative stress, inflammation, and postoperative cognitive impairment.

Figure Lengend Snippet: TMH does not affect other inflammasome or inflammatory pathways. (A,B) LPS-primed J774A.1 cells were treated with TMH for 2 h, followed by stimulation with either dsDNA (1 μg/mL) (A) or flagellin (B) transfected using Lipofectamine 2000 for 3 h. (C) Following TMH treatment (2 h), nuclear and cytosolic fractions of LPS-primed J774A.1 cells were separated and assessed for NF-κB p65 translocation by immunoblotting. (D) HEK293FT cells transfected with the pGL4.32 luciferase reporter vector were treated with TNF-α (20 ng/mL) for 5 h, with or without TMH pre-treatment (2 h). Luciferase activity was measured using the Bright-Glo™ luciferase assay system (Promega). Data are presented as the mean ± SD (n = 3).
