Rheumatoid arthritis (RA) is a chronic autoimmune condition characterized by inflammatory activity with distinct rhythmic fluctuations. However, the precise mechanisms governing these inflammatory rhythms remain elusive. Here, we explore the interaction between dietary patterns, gut microbiota diurnal oscillations, and the rhythmicity of RA in both collagen-induced arthritis (CIA) mice and patients with RA and highlight the significance of dietary timing in modulating RA inflammatory rhythms linked to gut microbiota. Specifically, we discovered that Parabacteroides distasonis (P. distasonis) uses β-glucosidase (β-GC) to release glycitein (GLY) from the diet in response to daily nutritional cues, influencing RA inflammatory rhythms dependent on the sirtuin 5-nuclear factor-κB (SIRT5-NF-κB) axis. Notably, we validated the daily fluctuations of P. distasonis-β-GC-GLY in patients with RA through continuous sampling across day-night cycles. These findings underscore the crucial role of dietary timing in RA rhythmicity and propose potential clinical implications for novel therapeutic strategies to alleviate arthritis.

饮食定时诱导的肠道微生物群昼夜振荡调节类风湿性关节炎的炎症节律



类风湿性关节炎 (RA) 是一种慢性自身免疫性疾病,其特征是炎症活动具有明显的节律波动。然而,控制这些炎症节律的确切机制仍然难以捉摸。在这里,我们探讨了胶原蛋白诱导的关节炎 (CIA) 小鼠和 RA 患者的饮食模式、肠道微生物群昼夜振荡和 RA 节律性之间的相互作用,并强调了饮食时间在调节与肠道微生物群相关的 RA 炎症节律中的重要性。具体来说,我们发现 Distasonis 副拟杆菌P. distasonis) 使用 β-葡萄糖苷酶 (β-GC) 从饮食中释放黄豆蛋白 (GLY) 以响应日常营养线索,影响依赖于 sirtuin 5-核因子-κB (SIRT5-NF-κB) 轴的 RA 炎症节律。值得注意的是,我们通过昼夜周期的连续采样验证了 RA 患者 P. distasonis-β-GC-GLY 的每日波动。这些发现强调了饮食时间在 RA 节律性中的关键作用,并为缓解关节炎的新型治疗策略提出了潜在的临床意义。
