Sirt6-mediated gut microbiota plays a vital role in poststroke depression (PSD). Icariside Ⅱ (ICS Ⅱ) is naturally-occurring neuroprotectant with Sirt6 induction potency. However, it unknown whether ICS protects against PSD through modulation of microbiota. This study aimed to reveal the effect and potential mechanisms on PSD, microbiota-gut-brain axis was investigated. Using middle cerebral artery occlusion (MCAO) chronic unpredictable mild stress (CUMS) establish post-stroke (PSD) mice, we assessed anti-depressant effects via behavioral tests, immunohistochemistry, western blot. Transcriptome profiling, molecular docking, surface plasmon resonance were used identify key targets. 16S rDNA genomic-derived taxonomic profiling fecal transplantation (FMT) conducted figure out mechanistic short-chain fatty acids (SCFAs). ameliorated depressive-like behaviors mice as evidenced by sucrose preference test, forced swimming test tail suspension test. restored mitochondrial function, reduced oxidative damage pro-inflammatory cytokines both brain intestine regulation Sirt6/NF-κB pathway. significantly increased abundance (such asAkkermansia Ligilactobacillus), enhanced SCFAs concentrations, repaired intestinal barrier integrity upreglated tight junction protein expression. FMT from II-treated replicated these benefits, confirming microbiota's role. Mechanistically, directly bound its activity. Ⅱ-mediated neuroprotection neutralized or hydrogen peroxide-induced enteric glial cells when absent. Our findings expand pharmacological properties II demonstrating ability ameliorate axis. Ⅱ, novel activator, could be translated into an alternative microbiota-targeted avenue for coping PSD.

Diabetic nephropathy (DN) is a chronic inflammatory disease that affects millions of diabetic patients worldwide. The key to treating DN early diagnosis and prevention. Once the patient enters clinical proteinuria stage, renal damage difficult reverse. Therefore, developing treatment methods critical. pathogenesis results from various factors, among which immune response inflammation play major roles. Ferroptosis newly discovered type programmed cell death characterized by iron-dependent lipid peroxidation excessive ROS production. Recent studies have demonstrated activation closely related occurrence development ferroptosis. Moreover, hyperglycemia induces iron overload, peroxidation, oxidative stress, inflammation, fibrosis, all are pathogenesis, indicating ferroptosis plays role in DN. this review focuses on regulatory mechanisms ferroptosis, mutual processes involved inflammation. By discussing analyzing relationship between DN, we can deepen our understanding develop new therapeutics targeting or inflammation-related for with

Cerebral ischemia/reperfusion causes exacerbated neuronal damage involving excessive neuroinflammation and oxidative stress. ROS is considered a signal molecule to activate NLRP3; thus, the ROS/NLRP3/pyroptosis axis plays vital role in pathogenesis of cerebral injury (CIRI). Therefore, targeting inhibition may be promising therapeutic tactic for CIRI.

Abstract Ferroptosis is a recently identified form of programmed cell death that plays an important role in the pathophysiological process osteoarthritis (OA). Herein, we investigated protective effect moderate mechanical stress on chondrocyte ferroptosis and further revealed internal molecular mechanism. Intra-articular injection sodium iodoacetate (MIA) was conducted to induce rat model OA vivo, meanwhile, interleukin-1 beta (IL-1β) treated chondrocytes vitro. The phenotype analyzed by histology microcomputed tomography, transmission electron microscope immunofluorescence. expression cartilage metabolism-related factors immunohistochemical Western blot. Animal experiments moderate-intensity treadmill exercise could effectively reduce matrix degradation MIA-induced rats. Cell showed 4-h cyclic tensile strain intervention activate Nrf2 inhibit NF-κB signaling pathway, increase Col2a1, GPX4, SLC7A11, decrease MMP13 P53, thereby restraining IL-1β-induced degeneration. Inhibition pathway relieved Meanwhile, overexpression recombinant lentivirus reversed positive CTS chondrocytes. Moderate antioxidant system, p65 regulating GPX4.
