Plasticity of skeletal muscle is induced by transcriptional and translational events in response to exercise, leading to multiple health and performance benefits. The skeletal muscle microenvironment harbors myofibers and mononuclear cells, but the rich cell diversity has been largely ignored in relation to exercise adaptations. Using our workflow of transcriptome profiling of individual myofibers, we observed that their exercise-induced transcriptional response was surprisingly modest compared with the bulk muscle tissue response. Through the integration of single-cell data, we identified a small mast cell population likely responsible for histamine secretion during exercise and for targeting myeloid and vascular cells rather than myofibers. We demonstrated through histamine H1 or H2 receptor blockade in humans that this paracrine histamine signaling cascade drives muscle glycogen resynthesis and coordinates the transcriptional exercise response. Altogether, our cellular deconstruction of the human skeletal muscle microenvironment uncovers a histamine-driven intercellular communication network steering muscle recovery and adaptation to exercise.
骨骼肌的可塑性是由转录和翻译事件诱导的,以对运动做出响应,从而对健康和运动表现产生多重益处。骨骼肌微环境蕴藏着肌纤维和单核细胞,但这种丰富的细胞多样性在很大程度上被忽视了与运动适应性的关系。利用我们对单个肌纤维进行转录组分析的工作流程,我们观察到,与大块肌肉组织的反应相比,运动诱导的转录反应出奇地温和。通过整合单细胞数据,我们确定了一小部分肥大细胞群,它们可能在运动过程中分泌组胺,并以髓细胞和血管细胞而不是肌纤维为目标。我们通过阻断人体组胺 H1 或 H2 受体证明,这种旁分泌型组胺信号级联可驱动肌糖原再合成并协调转录运动反应。总之,我们对人体骨骼肌微环境的细胞解构揭示了组胺驱动的细胞间通讯网络,它引导着肌肉的恢复和对运动的适应。

Systemic metabolism ensures energy homeostasis through inter-organ crosstalk regulating thermogenic adipose tissue. Unlike the well-described inductive role of the sympathetic system, the inhibitory signal ensuring energy preservation remains poorly understood. Here, we show that, via the mechanosensor Piezo2, sensory neurons regulate morphological and physiological properties of brown and beige fat and prevent systemic hypermetabolism. Targeting runt-related transcription factor 3 (Runx3)/parvalbumin (PV) sensory neurons in independent genetic mouse models resulted in a systemic metabolic phenotype characterized by reduced body fat and increased insulin sensitivity and glucose tolerance. Deletion of Piezo2 in PV sensory neurons reproduced the phenotype, protected against high-fat-diet-induced obesity, and caused adipose tissue browning and beiging, likely driven by elevated norepinephrine levels. Finding that brown and beige fat are innervated by Runx3/PV sensory neurons expressing Piezo2 suggests a model in which mechanical signals, sensed by Piezo2 in sensory neurons, protect energy storage and prevent a systemic hypermetabolic phenotype.
全身新陈代谢通过器官间的串联调节生热脂肪组织来确保能量平衡。与交感神经系统的诱导作用不同,确保能量保存的抑制信号仍然鲜为人知。在这里,我们展示了感觉神经元通过机械传感器 Piezo2 调节棕色和米色脂肪的形态和生理特性,并防止全身代谢亢进。在独立的遗传小鼠模型中,以Runt相关转录因子3(Runx3)/parvalbumin(PV)感觉神经元为靶点,可产生以体脂减少、胰岛素敏感性和葡萄糖耐受性增强为特征的全身代谢表型。PV 感觉神经元中 Piezo2 的缺失再现了这种表型,防止了高脂饮食引起的肥胖,并导致脂肪组织棕色化和米色化,这可能是由去甲肾上腺素水平升高驱动的。棕色和米色脂肪是由表达 Piezo2 的 Runx3/PV 感觉神经元支配的,这一发现提出了一个模型,在该模型中,感觉神经元中的 Piezo2 可感知机械信号,从而保护能量储存并防止出现全身高代谢表型。

Immune checkpoint blockade (ICB) therapy has revolutionized cancer treatment but remains effective in only a subset of patients. Emerging evidence suggests that the gut microbiome and its metabolites critically influence ICB efficacy. In this study, we performed a multi-omics analysis of fecal microbiomes and metabolomes from 165 patients undergoing anti-programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) therapy, identifying microbial and metabolic entities associated with treatment response. Integration of data from four public metagenomic datasets (n = 568) uncovered cross-cohort microbial and metabolic signatures, validated in an independent cohort (n = 138). An integrated predictive model incorporating these features demonstrated robust performance. Notably, we characterized five response-associated enterotypes, each linked to specific bacterial taxa and metabolites. Among these, the metabolite phenylacetylglutamine (PAGln) was negatively correlated with response and shown to attenuate anti-PD-1 efficacy in vivo. This study sheds light on the interplay among the gut microbiome, the gut metabolome, and immunotherapy response, identifying potential biomarkers to improve treatment outcomes.

Targeting gut S. aureofaciens Tü117 serves as a new potential therapeutic intervention for the prevention and treatment of hypertension

Currently, the regulation of specific gut microbial metabolism for the development and/or treatment of hypertension remains largely unexplored. Here, we show that α-lipomycin, produced by Streptomyces aureofaciens (S. aureofaciens) Tü117, is upregulated in the serum of high-salt diet (HSD) mice and patients with essential hypertension. α-lipomycin causes vasodilation impairment involving transient receptor potential vanilloid 4 (TRPV4)-mediated nitric oxide and endothelium-derived hyperpolarizing factor pathways in mice. We also find that Lactobacillus plantarum (L. plantarum) CCFM639 attenuates the increase in blood pressure (BP) potentially through inhibiting the proliferation of S. aureofaciens Tü117 in mice. An exploratory intervention trial indicates that L. plantarum CCFM639 supplementation reduces BPs in subjects newly diagnosed with pre-hypertension or stage 1 hypertension without antihypertensive medication. Our findings provide evidence for a role of S. aureofaciens Tü117-associated α-lipomycin elevation in the pathogenesis of HSD-induced hypertension, highlighting that targeting gut bacteria serves as a new therapeutic intervention for hypertension.

Fueling metabolic disruption via FMD to boost chemotherapy in TNBC

Triple-negative breast cancer (TNBC) is highly glycolytic and lacks effective biomarkers for therapy response. The BREAKFAST trial showed that a fasting-mimicking diet (FMD) improved pathological complete response (pCR) rates to 56.6% compared to historical chemotherapy averages (30%–40%), with minimal severe adverse events. FMD’s metabolic and immune-modulating effects warrant further study with immunotherapy.

The emerging role of dysregulated propionate metabolism and methylmalonic acid in metabolic disease, aging, and cancer

Propionate metabolism dysregulation has emerged as a source of metabolic health alterations linked to aging, cardiovascular and renal diseases, obesity and diabetes, and cancer. This is supported by several large cohort population studies and recent work revealing its role in cancer progression. Mutations in several enzymes of this metabolic pathway are associated with devastating inborn errors of metabolism, resulting in severe methylmalonic and propionic acidemias. Beyond these rare diseases, however, the broader pathological significance of propionate metabolism and its metabolites has been largely overlooked. Here, we summarize earlier studies and new evidence that the alteration of this pathway and associated metabolites are involved in the development of various metabolic diseases and link aging to cancer progression and metastasis.

There is growing evidence that micro-RNAs (miRNAs) are key players in the regulation of gut health. In this issue of Cell Metabolism, Li et al.1 uncovered that the dietary fiber stachyose can modulate the luminal miRNA load of the intestinal tracts by binding to HSP90β, thereby altering the gut’s microbial composition.
