Background: Periodontitis (PD) is a common chronic inflammatory oral disease that severely affects patients' quality of life. Fisetin has been shown to possess antioxidant and anti-inflammatory properties in various biological systems.
Methods: This study first identified the molecular targets of fisetin for PD through network pharmacology analysis. The therapeutic effects of fisetin were then evaluated in an animal model of PD and validated through in vitro experiments. Additionally, we utilised single-cell and spatial transcriptomics technologies to identify key cell populations in PD and their spatial distribution.
Results: The study demonstrated that fisetin significantly reduced alveolar bone destruction in the rat model of PD. Single-cell transcriptomics revealed that fisetin primarily affects fibroblast populations. In vitro experiments showed that fisetin alleviated the cytotoxicity caused by high oxidative stress levels in human periodontal ligament fibroblasts (PDLFs) .
Conclusion: Fisetin inhibits the progression of periodontitis by reducing oxidative stress levels in fibroblast populations. These findings support the potential of fisetin as a therapeutic agent for periodontitis and provide a scientific basis for future clinical trials and treatment strategies.
Clinical Relevance: By significantly reducing alveolar bone destruction and modulating fibroblast function, fisetin presents a novel therapeutic strategy for managing periodontitis. These results provide a scientific foundation for the design of clinical trials aimed at evaluating the efficacy of fisetin in PD patients. If validated in clinical settings, fisetin could be incorporated into treatment regimens, offering a pharmacological option that complements conventional periodontal therapies, thereby improving patient outcomes and quality of life.

Aging is a major risk factor for poor outcomes following respiratory infections. In animal models, the most severe outcomes of respiratory infections in older hosts have been associated with an increased burden of senescent cells that accumulate over time with age and create a hyperinflammatory response. Although studies using coronavirus animal models have demonstrated that removal of senescent cells with senolytics, a class of drugs that selectively kills senescent cells, resulted in reduced lung damage and increased survival, little is known about the role that senescent cells play in the outcome of influenza A viral (IAV) infections in aged mice.

Targeting senescent cells and the factors that accelerate this pathological state has recently emerged as a novel field in medicinal chemistry. As attention shifts to synthetic substances, studies on natural agents are often overlooked. In this paper, we present a detailed computational modeling study that encompasses quantum mechanics and molecular dynamics to elucidate the senotherapeutic activity of fisetin.

Ischemia brain injury is closely associated with the gut microbiota. Polysaccharides, as a typical prebiotic, have been extensively employed in stroke treatment. In our previous study, Pueraria lobata polysaccharide (PLP-3) with antioxidant activity was prepared via water extraction and alcohol precipitation combined with ultrasonic degradation.

Cellular senescence is an aging mechanism characterized by cell cycle arrest and a senescence-associated secretory phenotype (SASP). Preclinical studies demonstrate that senolytic drugs, which target survival pathways in senescent cells, can counteract age-associated conditions that span several organs. The comparative efficacy of distinct senolytic drugs for modifying aging and senescence biomarkers in vivo has not been demonstrated.
