Cells respond to the physical and geometrical tissue properties by multiple mechanotransduction mechanisms that can profoundly influence cells' decision-making, extending to cell metabolism. This review incorporates the most recent findings on this topic, organized along the idea that the mechano-metabolic connection serves three main functions, namely to inform systemic metabolism on the general functioning of a tissue/organ, to tune cells’ energy production with the mechanical requirements imposed by their surroundings, and to coordinate cell metabolism with cell fate choices induced in response to mechanical cues. This connection highlights the pervasive influence of mechanical cues on cell activity, opens interesting questions on its physiological and pathological roles, and lays the foundations for exploiting the mechano-metabolism axis to design new therapeutic approaches.
细胞通过多种机械转导机制响应组织的物理和几何特性,这些机制可以深刻地影响细胞的决策,延伸到细胞代谢。这篇综述结合了这一主题的最新发现,根据机械代谢联系有三个主要功能的观点进行组织,即为组织/器官的一般功能提供系统代谢信息,根据周围环境施加的机械需求调节细胞的能量产生,以及协调细胞代谢和细胞命运选择,以响应机械提示。这种联系突出了机械信号对细胞活动的普遍影响,开启了关于其生理和病理作用的有趣问题,并为利用机械代谢轴设计新的治疗方法奠定了基础。

The cell nucleus is a fascinating organelle. The myriad of fundamental processes that ensure that the genetic information is read correctly and faithfully transmitted provides a rich subject of research across time scales and model systems. Topics ranging from chromosome ‘metascale’ organization and division, enabled by molecular machineries like the kinetochore, to the organization of the genome that ensues cell division during interphase, which enables fine tuning of gene regulation, are subjects that we cover in the ‘Cell Nucleus’ issue of Current Opinion in Cell Biology.
细胞核是一个迷人的细胞器。确保遗传信息被正确读取和忠实传递的无数基本过程为跨时间尺度和模型系统的研究提供了丰富的主题。从染色体的“元尺度”组织和分裂(由着丝点等分子机制实现),到间期细胞分裂后的基因组组织(可实现基因调控的微调),这些主题都是我们在《细胞生物学最新观点》的“细胞核”问题中所涉及的主题。

The pH balance between extracellular and intracellular space is crucial for a multitude of cellular processes. Real-time observation of pH fluctuations in the range 4–9 in live cells and tissues in a sensitive, non-invasive manner has become feasible with advances in pH quantification by organic dyes, genetically encoded fluorescent proteins, and DNA-based probes. We discuss mechanisms through which pH affects cell cycle, transcription, senescence, neurotransmission, glycolipid-lectin driven endocytosis, tissue remodelling, immune responses, and GPCR signalling. Growth factor-stimulated acidification of the extracellular space notably triggers enzymatic reactions like desialylation at the plasma membrane that control processes involving cell migration and bone resorption. Research into the role of pH in cellular physiology continues to be a fertile ground for discovery that underscores its fundamental importance.
细胞外和细胞内空间的pH平衡对许多细胞过程至关重要。随着有机染料、遗传编码荧光蛋白和基于dna的探针的pH定量技术的进步,以一种灵敏、无创的方式实时观察活细胞和组织中4-9范围内的pH波动已经成为可能。我们讨论了pH影响细胞周期、转录、衰老、神经传递、糖脂-凝集素驱动的内吞作用、组织重塑、免疫反应和GPCR信号传导的机制。生长因子刺激的细胞外空间酸化尤其会引发酶促反应,如质膜上的脱盐作用,从而控制细胞迁移和骨吸收过程。对pH在细胞生理学中的作用的研究仍然是发现的沃土,强调了它的基本重要性。

Alzheimer's disease (AD) is characterized by a multifactorial pathophysiology. Beyond its classical hallmarks, growing evidence highlights vascular contributions, including hemostatic dysregulation and a prothrombotic state in AD. This review focuses on recent findings concerning two key blood clot components–fibrin(ogen) and platelets–and their roles in AD pathology, including fibrinogen's abnormal accumulation in the AD brain, its interaction with amyloid-β, together with the associated impacts on clot stability, vascular occlusion, and neuroinflammation; and the potential switch of platelets along the AD continuum from protective to deleterious. This review provides an update on the interplay between vascular dysfunction and AD, underscoring the need for comprehensive integrative research to address AD's complexity and advocating for personalized approaches to tackle this multifaceted disorder.
阿尔茨海默病(AD)具有多因素病理生理特征。除了经典特征外,越来越多的证据强调血管的作用,包括AD的止血失调和血栓形成前状态。本文综述了两种关键的血凝块成分——纤维蛋白(原)和血小板——及其在阿尔茨海默病病理中的作用,包括纤维蛋白原在阿尔茨海默病大脑中的异常积累,它与淀粉样蛋白-β的相互作用,以及对凝块稳定性、血管闭塞和神经炎症的相关影响;以及血小板沿着AD连续体从保护性到有害性的潜在转换。这篇综述提供了血管功能障碍与AD之间相互作用的最新进展,强调需要全面的综合研究来解决AD的复杂性,并倡导个性化的方法来治疗这种多方面的疾病。

During aging, the cardiac extracellular matrix (ECM) undergoes gradual remodeling that reduces the heart's ability to function. Specific ECM changes cause alterations in cellular signaling pathways, eliciting maladaptive responses. Here, we provide insight into the current knowledge of how age-specific ECM changes contribute to altered ligand–receptor interactions, dysregulated mechanotransduction, and the propagation of pro-fibrotic signaling cascades that underpin dysfunction. We also highlight regional and sex differences that new biomolecular and bioengineered technologies have recently uncovered. We call for new biomaterial strategies that mimic spatiotemporal and sex-specific ECM alterations to equip researchers with the tools to unravel complex cellular signaling events. We believe this can be achieved through interdisciplinary cooperation amongst researchers spanning matrix biology, biomaterials, spatial omics, and biomedical engineering.

Numerous stimuli activate the extracellular signal-regulated kinases ERK1/2, which phosphorylate a diverse range of substrates, regulating multiple cellular processes. The broad variety of functions controlled by these enzymes is enabled by complex intracellular organization, which requires precise spatiotemporal regulation. Scaffold proteins and the formation of molecular condensates by liquid–liquid phase separation (LLPS) are key in ERK1/2 signal modulation and output. This review provides an overview of ERK1/2 multifaceted actions, with a focus on the cytoskeleton, mitochondria, and metabolism, as well as ERK1/2 regulation by scaffolds and molecular condensates. We highlight recent findings that shed light on ERK1/2 regulation and discuss the implications for cellular functions, disease mechanisms, and therapeutic development.

Cells derive their shape, and in turn much of their behavior, from the organization of the cytoskeleton. While a myriad of proteins contribute to the regulation and organization of this dynamic structure, two of the principal components are actin filaments, which provide the structure, and myosin motors, which generate the majority of the forces. Here we review recent results on the assembly and kinetics of non-muscle myosin 2, and highlight how the cellular environment modulates local myosin behavior and signaling.

A molecular systems perspective on calcium oscillations beyond ion fluxes 离子通量以外钙振荡的分子系统视角

Calcium (Ca2+) oscillations, marked by periodic fluctuations in cytosolic Ca2+ levels, are a universal feature of both excitable and non-excitable cells, regulating key functions like immune responses, neuronal activity and oocyte activation. Despite significant progress over the past few decades in identifying the molecular toolkits involved in Ca2+ mobilization, fundamental questions remain unresolved: How do Ca2+oscillations arise? In dynamical systems, oscillations arise as closed-loop trajectories in phase space, known as limit cycles. In this framework, [Ca2+] is the variable that oscillates along the limit cycle. Is [Ca2+] also the control parameter that defines the system's stability? Understanding how oscillations arise and how instability is controlled are essential for determining what these oscillations encode. This review revisits classic categorizations of Ca2+ oscillation models, focusing on the minimal mathematical models, their assumptions and gaps linking models with experimental data. We examine historical arguments in light of recent discoveries of plasma membrane lipid oscillations in non-excitable cells. While growing evidence support the pivotal role of lipid signaling in regulating Ca2+ dynamics, they mostly focused on the upstream role of signaling in Ca2+ mobilization, rather than viewing membrane-dependent signal transduction as the core control loop that is responsible for oscillatory Ca2+ dynamics. Here we summarize recent molecular studies of phosphoinositide signaling in modulating Ca2+ dynamics, by considering a broader chemical perspective as essential for understanding Ca2+ oscillations beyond ion fluxes.
钙(Ca2+)振荡,以胞质Ca2+水平的周期性波动为标志,是可兴奋和不可兴奋细胞的普遍特征,调节免疫反应、神经元活性和卵母细胞活化等关键功能。尽管在过去的几十年里,在确定参与Ca2+动员的分子工具包方面取得了重大进展,但基本问题仍未解决:Ca2+振荡是如何产生的?在动力系统中,振荡以相空间中的闭环轨迹出现,称为极限环。在这个框架中,[Ca2+]是沿极限环振荡的变量。[Ca2+]也是定义系统稳定性的控制参数吗?了解振荡是如何产生的以及不稳定性是如何被控制的,对于确定这些振荡的编码是至关重要的。本文回顾了Ca2+振荡模型的经典分类,重点关注最小数学模型,它们的假设和连接模型与实验数据的差距。我们检查历史上的争论,根据最近发现的质膜脂振荡在不可兴奋的细胞。虽然越来越多的证据支持脂质信号在调节Ca2+动力学中的关键作用,但他们主要关注Ca2+动员中信号的上游作用,而不是将膜依赖性信号转导视为负责振荡Ca2+动力学的核心控制回路。在这里,我们总结了最近的磷酸肌苷信号在调节Ca2+动力学的分子研究,通过考虑一个更广泛的化学角度作为必要的理解Ca2+振荡超越离子通量。

Septins are cytoskeletal guanosine triphosphate (GTP)-binding proteins that were discovered in budding yeast and are conserved from algae and protists to mammals. Septins assemble into heteromeric complexes, which can polymerize into filaments and higher-order filament architectures, and perform functions in a wide range of biological processes, including cell division and motility and tissue morphogenesis. Although septin dysfunction in animals is linked to infertility, defective organogenesis, neurodegenerative diseases, and cancer, the molecular mechanisms underlying septin function are not clear. Studies of septins in vivo in whole animals provide a powerful approach for gaining insights into the role of septins in animal pathophysiology and unraveling the molecular and cell biological basis of septin function.
septin是在出芽酵母中发现的细胞骨架鸟苷三磷酸(GTP)结合蛋白,从藻类和原生生物到哺乳动物都保存下来。septin组装成异质复合物,可以聚合成细丝和高阶细丝结构,并在广泛的生物过程中发挥作用,包括细胞分裂、运动和组织形态发生。虽然动物的septin功能障碍与不育、器官发生缺陷、神经退行性疾病和癌症有关,但septin功能的分子机制尚不清楚。在全动物体内对septin的研究为深入了解septin在动物病理生理中的作用以及揭示septin功能的分子和细胞生物学基础提供了强有力的途径。
