    癫痫,一种以长时间和过度癫痫发作为特征的神经系统疾病,与肿瘤抑制基因p53水平升高有关,p53会导致神经元功能障碍。这篇综述探讨了p53在癫痫中的分子机制,并讨论了潜在的未来治疗策略。研究表明,在神经元凋亡过程中p53表达的变化,神经炎症,氧化应激在癫痫的发病机制中起着重要作用。升高的p53破坏谷氨酸能神经传递并过度激活NMDA和AMPA受体,导致神经元钙流入增加,线粒体氧化应激,和激活凋亡途径介导的神经元功能障碍,加剧了癫痫的发生.p53参与癫痫表明,靶向该蛋白可能有利于减轻神经元损伤和预防癫痫复发。像吡虫啉-α这样的药物在减少p53介导的细胞凋亡和癫痫发作严重程度方面显示出希望。基因治疗方法,例如病毒载体介导的野生型p53或靶向突变型p53的RNA干扰递送,也有效地恢复了正常的p53功能和降低癫痫发作易感性。尽管取得了这些进展,癫痫的异质性和p53调控的潜在长期副作用提出了挑战.未来的研究应该集中在阐明p53的精确分子机制和开发个性化的治疗策略上。调节p53活性有望降低癫痫发作易感性并改善癫痫患者的生活质量。本综述提供了对p53在神经炎症通路中的复杂作用的理解。包括JAK-STAT,JNK,NF-κB,刺猬索尼克,Wnt,对于开发靶向疗法至关重要。
    Epilepsy, a neurological disorder characterized by prolonged and excessive seizures, has been linked to elevated levels of the tumor suppressor gene p53, which contributes to neuronal dysfunction. This review explores the molecular mechanisms of p53 in epilepsy and discusses potential future therapeutic strategies. Research indicates that changes in p53 expression during neuronal apoptosis, neuroinflammation, and oxidative stress play a significant role in the pathogenesis of epilepsy. Elevated p53 disrupts glutamatergic neurotransmission and hyperactivates NMDA and AMPA receptors, leading to increased neuronal calcium influx, mitochondrial oxidative stress, and activation of apoptotic pathways mediated neuronal dysfunction, exacerbating epileptogenesis. The involvement of p53 in epilepsy suggests that targeting this protein could be beneficial in mitigating neuronal damage and preventing seizure recurrence. Pharmacological agents like pifithrin-α have shown promise in reducing p53-mediated apoptosis and seizure severity. Gene therapy approaches, such as viral vector-mediated delivery of wild-type p53 or RNA interference targeting mutant p53, have also been effective in restoring normal p53 function and reducing seizure susceptibility. Despite these advances, the heterogeneous nature of epilepsy and potential long-term side effects of p53 modulation present challenges. Future research should focus on elucidating the precise molecular mechanisms of p53 and developing personalized therapeutic strategies. Modulating p53 activity holds promise for reducing seizure susceptibility and improving the quality of life for individuals with epilepsy. The current review provides the understanding the intricate role of p53 in neuroinflammatory pathways, including JAK-STAT, JNK, NF-κB, Sonic Hedgehog, and Wnt, is crucial for developing targeted therapies.

    组织蛋白酶B(CTSB)是半胱氨酸蛋白酶家族的一员,主要负责在溶酶体的酸性环境中降解不必要的细胞器和蛋白质,以促进回收。最近的研究表明,CTSB除了在溶酶体中作为蛋白水解酶的功能外,还发挥着多方面的作用。重要的是,最近的数据表明,CTSB对不同的心脏病理状况有显著影响,如动脉粥样硬化(AS),心肌梗塞,高血压,心力衰竭和心肌病。特别是在AS的背景下,临床前模型和临床样本成像数据表明,基于组织蛋白酶活性的探针可以可靠地成像泡沫细胞和动脉粥样硬化斑块中的CTSB活性;同时,它允许同步诊断和治疗干预。然而,我们对CTSB在心血管疾病中的认识仍处于早期阶段。本文旨在全面综述CTSB在心血管生理和病理中的意义,目的是为开发靶向CTSB的药物奠定理论基础。
    Cathepsin B (CTSB) is a member of the cysteine protease family, primarily responsible for degrading unnecessary organelles and proteins within the acidic milieu of lysosomes to facilitate recycling. Recent research has revealed that CTSB plays a multifaceted role beyond its function as a proteolytic enzyme in lysosomes. Importantly, recent data suggest that CTSB has significant impacts on different cardiac pathological conditions, such as atherosclerosis (AS), myocardial infarction, hypertension, heart failure and cardiomyopathy. Especially in the context of AS, preclinical models and clinical sample imaging data indicate that the cathepsin activity-based probe can reliably image CTSB activity in foam cells and atherosclerotic plaques; concurrently, it allows synchronous diagnostic and therapeutic interventions. However, our knowledge of CTSB in cardiovascular disease is still in the early stage. This paper aims to provide a comprehensive review of the significance of CTSB in cardiovascular physiology and pathology, with the objective of laying a theoretical groundwork for the development of drugs targeting CTSB.

    Breast cancer (BC) is a prevalent malignancy globally. Autophagy plays a pivotal role in all stages of this disease, including development, metastasis, and onset. Therefore, it is envisaged that targeting cell autophagy through appropriate tactics would evolve into a novel breast cancer prevention and therapy strategy. A multitude of chemotherapeutic medications can stimulate autophagy in tumor cells. It has led to divergent opinions on the function of autophagy in cancer treatment, as both stimulating and blocking autophagy can improve the effectiveness of anticancer medications. Consequently, the decision of whether to stimulate or inhibit autophagy during breast cancer treatment has become crucial. Understanding the distinctive mechanisms of autophagy in BC and its significance in medication therapy might facilitate the creation of targeted treatment plans based on the roles particular to autophagy. This review summarizes recent studies on the autophagy mechanism in breast cancer and provides insights into autophagy-based BC therapeutic techniques, giving fresh avenues for future BC treatment.

    抗生素耐药性是当今全球健康最重要的问题之一。因此,越来越多的不同的感染越来越难以用常规药物治疗,而新抗生素的研发越来越少这一事实使这种情况更加恶化。在这种情况下,基于阻断或减弱毒力途径的策略可以作为非常有趣的治疗方法,因为它们不关注细菌根除,这应该减少施加在病原体上的选择压力。这种毒力消耗可以通过抑制保守的群体感应(QS)系统来实现,一种使细菌能够以密度依赖的方式相互交流的机制。QS调节基因表达,导致一些重要过程的激活,例如毒力和生物膜形成等。因此,这篇综述指出了迄今为止报道的破坏多重耐药病原体铜绿假单胞菌QS系统不同步骤的方法。为了这个目标,作者描述了不同类型的分子(酶,天然和合成的小分子,抗体。)已经被鉴定为铜绿假单胞菌群体猝灭剂(QQs)或QS抑制剂(QSI),根据它们阻断的QS电路分组(Las,Rhl,Pqs和一些来自有争议的途径Iqs的例子)。发现新QSI和QQs的重要性有望有助于减少抗生素剂量或至少充当佐剂以增加抗生素治疗效果。此外,本文还重点介绍了每种策略的优点和可能的缺点,并总结了该领域的未来前景。
    Antibiotic resistance is one of the most important concerns in global health today. Thus, a growing number of different infections are becoming harder to treat with conventional drugs and this is aggravated by the fact that fewer new antibiotics are being developed. In this context, strategies based on blocking or attenuating virulence pathways could position as very interesting therapeutic approaches since they do not focus on bacteria eradication, which should reduce the selective pressure exerted on the pathogen. This virulence depletion can be achieved by inhibiting the conserved quorum sensing (QS) system, a mechanism that enables bacteria to communicate one another in a density dependent manner. QS regulates gene expression leading to the activation of some important processes such as virulence and biofilm formation among others. Therefore, this review points out the approaches reported so far for disrupting different steps of the QS system of the multiresistant pathogen Pseudomonas aeruginosa. With this aim, the authors describe different types of molecules (enzymes, natural and synthetic small molecules, antibodies…) already identified as P. aeruginosa quorum quenchers (QQs) or QS inhibitors (QSIs) grouped according to the QS circuit that they block (Las, Rhl, Pqs and some examples from the controversial pathway Iqs). The importance of the discovery of new QSIs and QQs is expected to help on reducing antibiotic doses or at least to act as adjuvants to increase antibiotic treatment effect. Moreover, this article also highlights the advantages and possible drawbacks of each strategy and it also summarizes future perspectives in the field.

    In the realm of this study, obtaining a comprehensive understanding of ischemic brain injury and its molecular foundations is of paramount importance. Our study delved into single-cell data analysis, with a specific focus on sub-celltypes and differentially expressed genes in the aftermath of ischemic injury. Notably, we observed a significant enrichment of the \"ATP METABOLIC PROCESS\" and \"ATP HYDROLYSIS ACTIVITY\" pathways, featuring pivotal genes such as Pbx3, Dguok, and Kif21b. A remarkable finding was the consistent upregulation of genes like Fabp7 and Bcl11a within the MCAO group, highlighting their crucial roles in regulating the pathway of mitochondrial ATP synthesis coupled proton transport. Furthermore, our network analysis unveiled pathways like \"Neuron differentiation\" and \"T cell differentiation\" as central in the regulatory processes of sub-celltypes. These findings provide valuable insights into the intricate molecular responses and regulatory mechanisms that govern brain injury. The shared differentially expressed genes among sub-celltypes emphasize their significance in orchestrating responses post-ischemic injury. Our research, viewed from the perspective of a medical researcher, contributes to the evolving understanding of the molecular landscape underlying ischemic brain injury, potentially paving the way for targeted therapeutic strategies and improved patient outcomes.

    Mitochondria, pivotal organelles governing cellular biosynthesis, energy metabolism, and signal transduction, maintain dynamic equilibrium through processes such as biogenesis, fusion, fission, and mitophagy. Growing evidence implicates mitochondrial dysfunction in a spectrum of respiratory diseases including acute lung injury/acute respiratory distress syndrome, bronchial asthma, pulmonary fibrosis, chronic obstructive pulmonary disease, and lung cancer. Consequently, identifying methods capable of ameliorating damaged mitochondrial function is crucial for the treatment of pulmonary diseases. Extracellular vesicles (EVs), nanosized membrane vesicles released by cells into the extracellular space, facilitate intercellular communication by transferring bioactive substances or signals between cells or organs. Recent studies have identified abundant mitochondrial components within specific subsets of EVs, termed mitochondrial extracellular vesicles (mitoEVs), whose contents and compositions vary with disease progression. Moreover, mitoEVs have demonstrated reparative mitochondrial functions in injured recipient cells. However, a comprehensive understanding of mitoEVs is currently lacking, limiting their clinical translation prospects. This Review explores the biogenesis, classification, functional mitochondrial cargo, and biological effects of mitoEVs, with a focus on their role in pulmonary diseases. Emphasis is placed on their potential as biological markers and innovative therapeutic strategies in pulmonary diseases, offering fresh insights for mechanistic studies and drug development in various pulmonary disorders.
