全球健康与长寿每日简报Global Health & Longevity Daily Briefing

中湖南师范大学杨焕胜团队与印遇龙团队合作在Microbiome发表跨物种研究：肥胖机体肠道革兰氏阴性菌扩张、血清内毒素升高，LPS经EGR1转录因子驱动巨噬细胞M1极化，形成全身代谢性炎症。补充丁酸梭菌、丁酸或精氨酸，或抑制EGR1，均可显著减轻小鼠体重增幅、肝脂沉积并改善糖耐量，为肥胖的菌群-免疫联合干预给出清晰靶点。

ENA cross-species study by Yang Huansheng's team at Hunan Normal University, published in Microbiome, shows that in obesity, expansion of gram-negative gut bacteria raises serum LPS, which drives M1 macrophage polarization via the EGR1 transcription factor and fuels systemic metabolic inflammation. Supplementing Clostridium butyricum, butyrate or arginine—or inhibiting EGR1—markedly reduced weight gain, hepatic fat and impaired glucose tolerance in mice, pointing to a clear microbiome-immune target for obesity intervention.

中江南大学孙嘉、潘礼龙团队联合上海交通大学邹多武等在Gastroenterology发表研究，整合多中心慢性胰腺炎患者宏基因组、小鼠模型与巨噬细胞实验，鉴定出一类高表达HtpG的大肠杆菌可促进胰腺纤维化，揭示了肠道菌群在慢性胰腺炎进展中的因果作用，为以微生态为靶点的胰腺疾病干预提供了机制依据。

ENA team led by Sun Jia and Pan Lilong of Jiangnan University with Zou Duowu of Shanghai Jiao Tong University, publishing in Gastroenterology, integrated multi-center metagenomics from chronic pancreatitis patients with mouse models and macrophage experiments. They identified HtpG-high-expressing E. coli that promotes pancreatic fibrosis, establishing a causal role for gut microbes in disease progression and supporting microbiome-targeted strategies for pancreatic disorders.

中Nature Communications发表的一项泛基因组研究系统解析了脱硫弧菌属的广泛基因组多样性，发现不同物种携带的功能性状差异显著，其中特定鞭毛蛋白能够破坏肠道免疫耐受，与炎症性肠病等疾病相关。该工作提示判断硫酸盐还原菌的致病潜力必须细化到物种与效应分子层面，而非停留在属水平。

ENA pan-genomic study in Nature Communications systematically mapped the extensive genomic diversity of the genus Desulfovibrio, revealing pronounced species-specific functional traits. Certain flagellins were shown to undermine gut immune tolerance and have been linked to inflammatory bowel disease. The work suggests that assessing the pathogenic potential of sulfate-reducing bacteria requires species- and effector-level resolution rather than genus-level labels.

中Science Immunology发表的研究发现，肠道淋巴滤泡相关上皮中的簇细胞与M细胞形成功能协同：簇细胞放大2型黏膜免疫应答并促进IgA产生，与M细胞共同构成肠道黏膜免疫的"双哨兵"结构。该发现深化了对肠道上皮如何平衡免疫防御与耐受的理解，也为益生菌与黏膜疫苗设计提供了新的上皮靶点。

ENResearch published in Science Immunology shows that tuft cells in follicle-associated epithelium of the gut cooperate with M cells: tuft cells amplify type 2 mucosal immunity and boost IgA production, forming a dual-sentinel architecture with M cells. The finding deepens understanding of how the gut epithelium balances defense and tolerance, and suggests new epithelial targets for probiotic and mucosal vaccine design.

中ScienceDaily报道的最新研究揭示了衰老细胞（"僵尸细胞"）逃避免疫清除的关键机制：它们通过特定的分子伪装躲过免疫系统的监视，从而在组织中持续累积并释放促炎因子，驱动慢性炎症与组织老化。理解这一"隐身术"为开发增强免疫清除衰老细胞的抗衰疗法提供了直接靶点，是衰老细胞清除策略的重要补充。

ENNew research covered by ScienceDaily reveals how senescent 'zombie cells' evade immune surveillance through specific molecular camouflage, allowing them to accumulate in tissues and secrete pro-inflammatory factors that drive chronic inflammation and tissue aging. Understanding this hiding mechanism offers direct targets for anti-aging therapies designed to boost immune clearance of senescent cells, complementing existing senolytic strategies.

中ScienceDaily报道一项跨越47年的纵向研究，绘制了人体肌肉力量随年龄变化的长期轨迹，确定了力量开始加速流失的关键年龄节点。该发现对长寿医学意义重大：力量下降是失能与死亡风险的强预测因子，锁定"窗口期"意味着抗阻训练与蛋白质营养干预可在力量明显滑坡前提前介入，为延长健康寿命给出可操作的时间表。

ENA 47-year longitudinal study covered by ScienceDaily charted the long-term trajectory of muscle strength across aging and identified the critical age at which strength decline accelerates. Because declining strength strongly predicts disability and mortality, pinning down this window means resistance training and protein-focused nutrition can be deployed before the slide begins—an actionable timetable for extending healthspan.

中发表于Open Medicine的研究发现，老年大鼠韧带愈合缓慢的根源在于间充质干细胞自噬能力下降。研究者通过基因技术让干细胞过表达自噬关键基因ATG5后移植，不仅促进胶原有序排列与血管新生，还将巨噬细胞从促炎M1型转为抗炎M2型，显著提升老年韧带修复力，为老年运动损伤的干细胞疗法提供了"先抗衰、再修复"的新思路。

ENA study in Open Medicine traced slow ligament healing in aged rats to reduced autophagy in mesenchymal stem cells. By engineering the cells to overexpress the autophagy gene ATG5 before transplantation, researchers promoted organized collagen alignment and new vessel growth, and shifted macrophages from pro-inflammatory M1 to reparative M2 phenotypes, markedly improving healing—suggesting an 'anti-age the cell, then repair' strategy for geriatric musculoskeletal injuries.

中一项新研究鉴定出乳腺癌治疗后产生的微小RNA miR-3155b，它像精准"刹车片"一样直接关闭引发炎症与肿瘤复发的衰老分泌因子（SASP），且不伤害正常细胞。该发现把细胞衰老研究从"清除"扩展到"驯化"——在不杀死衰老细胞的前提下中和其有害分泌，为减轻放化疗副作用及更温和的抗衰干预提供了全新靶点。

ENNew research identifies microRNA miR-3155b, produced after breast cancer treatment, which acts as a precise brake that directly silences the senescence-associated secretory phenotype (SASP) driving inflammation and tumor recurrence—without harming healthy cells. The finding extends senescence research from 'clearance' to 'taming,' neutralizing harmful secretions while leaving senescent cells alive, and opens a fresh target for softer anti-aging interventions and fewer radio-chemotherapy side effects.

中俄勒冈健康与科学大学团队分析近20万人数据发现，习惯深夜进食与代谢功能障碍相关脂肪性肝病风险升高最多达30%相关，进食时序本身独立于总热量摄入构成风险因素。研究强调"什么时候吃"与"吃什么"同样重要，为 chrono-nutrition（时间营养学）在脂肪肝一级预防中的应用提供了大样本流行病学支持。

ENAnalyzing data from nearly 200,000 people, researchers at Oregon Health & Science University found that habitual late-night eating is associated with up to a 30% higher risk of metabolic dysfunction-associated steatotic liver disease, with meal timing acting as a risk factor independent of total caloric intake. The study underscores that 'when we eat' matters as much as 'what we eat,' providing large-scale epidemiological support for chrono-nutrition in primary prevention of fatty liver disease.

中发表于MedComm的随机饮食干预研究纳入48名健康成年人，等热量条件下进行一个月纯素与高肉饮食对照：尽管体重无明显变化，纯素组DNA甲基化谱偏向抗炎、抑癌与衰老相关通路改善，免疫细胞构成趋向更抗炎的稳态，部分表观遗传指标提示生物学衰老放缓。研究者提醒观察期仅4周且样本有限，长期效应与临床意义仍需验证。

ENA randomized dietary intervention published in MedComm assigned 48 healthy adults to isocaloric vegan versus high-meat diets for one month. With no significant weight change, the vegan group's DNA methylation profile shifted toward anti-inflammatory, cancer-suppressive and longevity-related pathways, with immune cell composition trending toward a calmer state and epigenetic markers suggesting slower biological aging. The authors caution that four weeks and a small sample warrant longer, larger studies.

中发表于British Journal of Nutrition的福清队列研究（21,476名成人）显示，膳食质量最高组的糖尿病风险较最低组低14%–28%，11项血液炎症标志物可解释约9%的关联。研究提示膳食质量部分通过降低系统性炎症改善代谢健康，为抗炎膳食干预提供人群证据。

ENA Fuqing Cohort study of 21,476 adults published in the British Journal of Nutrition found that those with the highest diet quality had 14%–28% lower odds of diabetes than the lowest group, depending on the scoring system, with eleven circulating inflammatory markers mediating about 9% of the association. The results suggest diet quality partly protects metabolic health by dampening systemic inflammation, supporting anti-inflammatory dietary patterns as a precision-nutrition target.

中昆明理工大学储传奇团队发表于Journal of Advanced Research的研究显示，灭活益生菌发酵的罗望子果肉可通过调节肠道色氨酸分解代谢与AhR-NLRP3信号轴，改善顽固性便秘模型。该研究把传统药食同源食材与菌群-代谢组学机制对接，为功能性食品干预功能性胃肠病提供了"发酵增效"的精准营养思路。

ENA team led by Chu Chuanqi at Kunming University of Science and Technology, publishing in the Journal of Advanced Research, showed that heat-inactivated probiotic-fermented tamarind pulp alleviates refractory constipation by modulating gut tryptophan catabolism and the AhR-NLRP3 axis. By linking a traditional food-medicine ingredient to microbiome-metabolomics mechanisms, the work offers a 'fermentation-boosted' precision nutrition strategy for functional gastrointestinal disorders.
