Triggering receptor expressed on myeloid cells 2 (TREM2)-mediated microglial phagocytosis is an energy-intensive process that plays a crucial role in amyloid beta (Aβ) clearance in Alzheimer's disease (AD). Energy metabolic reprogramming (EMR) in microglia induced by TREM2 presents therapeutic targets for cognitive impairment in AD. Jiawei Xionggui Decoction (JWXG) has demonstrated effectiveness in enhancing energy supply, protecting microglia, and mitigating cognitive impairment in APP/PS1 mice. However, the mechanism by which JWXG enhances Aβ phagocytosis through TREM2-mediated EMR in microglia remains unclear. This study investigates how JWXG facilitates microglial phagocytosis and alleviates cognitive deficits in AD through TREM2-mediated EMR. Microglial phagocytosis was evaluated through immunofluorescence staining in vitro and in vivo. The EMR level of microglia was assessed using high-performance liquid chromatography (HPLC) and enzyme-linked immunosorbent assay (ELISA) kits. The TREM2/protein kinase B (Akt)/mammalian target of rapamycin (mTOR)/hypoxia-inducible factor-1α (HIF-1α) signaling pathway was analyzed using Western blotting in BV₂ cells. TREM2^-/- BV₂ cells were utilized for reverse validation experiments. The Aβ burden, neuropathological features, and cognitive ability in APP/PS1 mice were evaluated using ELISA kits, immunohistochemistry (IHC), and the Morris water maze (MWM) test. JWXG enhanced both the phagocytosis of EMR disorder-BV₂ cells (EMRD-BV₂) and increased EMR levels. Notably, these effects were significantly reversed in TREM2^-/- BV₂ cells. JWXG elevated TREM2 expression, adenosine triphosphate (ATP) levels, and microglial phagocytosis in APP/PS1 mice. Additionally, JWXG reduced Aβ-burden, neuropathological lesions, and cognitive deficits in APP/PS1 mice. In conclusion, JWXG promoted TREM2-induced EMR and enhanced microglial phagocytosis, thereby reducing Aβ deposition, improving neuropathological lesions, and alleviating cognitive deficits.

Objective:To investigate whether endogenous hydrogen sulfide (H2 S)was involved in the pathogenesis of osteoarthritis (OA)and its underlying mechanism,to detect H2 S and its synthases ex-pression in knee cartilage in patients diagnosed with different severity of OA,and to explore the transcrip-tion and expression of gene MMP-13 in chondrocytes treated with IL-1βor H2S.Methods:Synovial fluids of the in-patients with different severity of OA hospitalized in Peking University First Hospital were collected for measurement of H2 S content using methylene blue assay.Articular cartilages of the patients who underwent knee arthroplasty were collected for the cell culture of relatively normal chondrocytes.The chondrocytes were cultured to the P3 generation and H2 S molecular probes were used for detection of endogenous H2 S generation in the chondrocytes.Immunocytochemistry was used to detect the localization of H2 S synthases including cystathionine β-synthase (CBS),cystathionine-γ-lyase (CSE),and mercap-topyruvate sulfurtransferase (MPST)in OA chondrocytes.Western blot was used to quantify the protein expressions of CSE,MPST,and CBS in cartilage tissues of the patients who were diagnosed with OA and underwent knee arthroplasty.The relatively normal human chondrocytes were cultured to passage 3 and then divided into 4 groups for different treatments:(1 )the normal control group,no reagent was added;(2)the IL-1βgroup,5 μg/L of IL-1βwas added;(3)the IL-1β+H2S group,200 μmol/L of NaHS was added 30 min before adding 5 μg/L of IL-1β;(4)the H2 S group,200 μmol/L of NaHS was added. The transcription and expression of gene MMP-13 in chondrocytes of each group were determined with Real-time PCR and Western blot,respectively.And the total NF-κB p65 and phosphorylated NF-κB p65 in chondrocytes were detected with Western blot.Results:The content of H2 S in the synovial fluid of degenerative knee was (14.3 ±3.3)μmol/L.Expressions of endogenous H2 S and its synthases including CBS,CSE and MPST were present in the cytoplasm of chondrocytes.CSE protein expression in Grade 3 (defined by outerbridge grading)cartilage tissues was significantly increased as compared with that of Grade 1 cartilage tissues (1.67 ±0.09 vs.1.26 ±0.11,P<0.05).However,no significant difference of CBS or MPST expression among the different groups was observed.The expression of MMP-13 protein in the IL-1βgroup was significantly higher than that in the normal chondrocytes (1 .87 ±0.67 vs.0.22 ± 0.10,P<0.05 ),and that in the IL-1β+H2 S group was significantly decreased than that in the IL-1βgroup (0.55 ±0.11 vs.1.87 ±0.67,P<0.05),and that in the H2S group had no significant difference compared with that in the normal control group.The transcription of MMP-13 protein in the IL-1βgroup was significantly higher than that in the normal chondrocytes (31.40 ±0.31 vs.1.00 ±0.00,P<0.05), and that in the IL-1β+H2 S group was significantly decreased than that in the IL-1βgroup (24.41 ± 1.28 vs.31.40 ±0.31,P<0.05),and that in the H2S group had no significant difference compared with that in the normal control group.The total NF-κB p65 in the IL-1βgroup was significantly higher than that in the normal chondrocytes (2.13 ±0.08 vs.0.73 ±0.08,P<0.05),and that in the IL-1β+H2S group was significantly decreased than that in the IL-1βgroup (1 .24 ±0.13 vs.2.13 ±0.08,P<0.05 ),and that in the H2 S group had no significant difference compared with that in the normal control group.The phosphorylated NF-κB p65 in IL-1βgroup was significantly higher than that in the normal chondrocytes (1.30 ±0.13 vs.0.19 ±0.04,P<0.05),and that in IL-1β+H2S group was significantly decreased than that in the IL-1βgroup (0.92 ±0.26 vs.1.30 ±0.13,P<0.05),and that in the H2S group had no significant difference compared with that in the normal control group.Conclusion:H2 S affected the cartilage degeneration by partly inhibiting the degradation of extracellular matrix.
