  • Pyroptosis is a programmed death mediated by activated caspase and Gasdermin family proteins, characterized by cell swelling, cytosolysis and release of inflammatory factors. Leukemia is a malignant disease characterized by abnormal differentiation and proliferation of hematopoietic stem cells, thus seriously threating human health. In recent years, it has been found that the transformation, proliferation, metastasis and treatment response of leukemia cells are closely related to pyrodeath. Pyroptosis provides a new perspective for the study of leukemia. This paper reviews the types and molecular mechanisms of pyroptosis, the role of pyroptosis in the occurrence and development of leukemia and the treatment of leukemia, so as to provide some references for further study of the relationship between pyroptosis and leukemia, in order to provide a new strategy for the treatment of leukemia.

    本研究旨在回顾在理解神经程序性细胞死亡(PCD)机制方面的最新进展,为临床研究提供有价值的见解。
    这篇综述涉及对神经PCD文献的深入分析,包括近年来进行的研究。该方法包括对研究结果及其含义的广泛审查。
    该评论建议PCD是一个过程,其特征是由特定因素或信号触发的细胞脱氧核糖核酸(DNA)的早期降解。它在生物体发育过程中起着重要作用。PCD包括两种主要形式:程序性坏死和凋亡。细胞凋亡是胱天蛋白酶依赖性的,在信号通路方面有明确的定义,而程序性坏死是不依赖胱天蛋白酶的,及其信号通路仍不清楚。维持细胞内平衡至关重要,PCD遵循一个涉及激活的全面过程,移情,和凋亡阶段。特定的基因调节这个过程,导致致命蛋白质的产生。然而,精确的机制仍未完全理解,值得进一步探索。
    这篇综述揭示了神经PCD的复杂机制。虽然取得了实质性进展,许多方面仍然需要深入调查。这些发现为该领域未来的临床研究提供了宝贵的基础。
    UNASSIGNED: This study aimed to review recent advancements in understanding neural programmed cell death (PCD) mechanisms, providing valuable insights for clinical research.
    UNASSIGNED: The review involves an in-depth analysis of the literature on neural PCD, encompassing studies conducted in recent years. The methodology includes an extensive examination of research findings and their implications.
    UNASSIGNED: The review suggested that PCD is a process characterized by the early degradation of cellular deoxyribonucleic acid (DNA) triggered by specific factors or signals. It plays a significant role during organism development. PCD comprises two primary forms: programmed necrosis and apoptosis. Apoptosis is caspase-dependent and well-defined in terms of signaling pathways, whereas programmed necrosis is caspase-independent, and its signaling pathways remain unclear. Maintaining intracellular equilibrium is vital, and PCD follows a comprehensive process involving activation, transference, and apoptosis stages. Specific genes regulate this process, leading to the production of lethal proteins. However, the precise mechanisms remain incompletely understood, warranting further exploration.
    UNASSIGNED: This review sheds light on the intricate mechanisms of neural PCD. While substantial progress has been made, many aspects still require in-depth investigation. The findings offer a valuable foundation for future clinical research in this field.

    半胱天冬酶是属于半胱氨酸蛋白酶家族的蛋白水解酶,并且在稳态和程序性细胞死亡中起关键作用。半胱天冬酶根据其在细胞凋亡(哺乳动物中的半胱天冬酶-3、半胱天冬酶-6、半胱天冬酶-7、半胱天冬酶-8和半胱天冬酶-9)和炎症(人类中的半胱天冬酶-1、半胱天冬酶-4、半胱天冬酶-5和半胱天冬酶-12中的已知作用被广泛分类。和小鼠中的caspase-1,caspase-11和caspase-12)。参与细胞凋亡的半胱天冬酶根据其作用机制被分类为起始半胱天冬酶(半胱天冬酶-8和半胱天冬酶-9)或执行者半胱天冬酶(半胱天冬酶-3、半胱天冬酶-6和半胱天冬酶-7)。参与凋亡的胱天蛋白酶被称为凋亡抑制剂(IAP)的蛋白质抑制。除了细胞凋亡,胱天蛋白酶在坏死性凋亡中起作用,焦亡,和自噬,是非凋亡性细胞死亡过程。半胱天冬酶的失调在许多人类疾病中表现突出。包括癌症,自身免疫,和神经退行性疾病,越来越多的证据表明,改变caspase活性可以带来治疗益处。这篇综述涵盖了不同类型的胱天蛋白酶,他们的功能,以及它们在不同生物中的生理和生物活性和作用。
    Caspases are proteolytic enzymes that belong to the cysteine protease family and play a crucial role in homeostasis and programmed cell death. Caspases have been broadly classified by their known roles in apoptosis (caspase-3, caspase-6, caspase-7, caspase-8, and caspase-9 in mammals) and in inflammation (caspase-1, caspase-4, caspase-5, and caspase-12 in humans, and caspase-1, caspase-11, and caspase-12 in mice). Caspases involved in apoptosis have been subclassified by their mechanism of action as either initiator caspases (caspase-8 and caspase-9) or executioner caspases (caspase-3, caspase-6, and caspase-7). Caspases that participate in apoptosis are inhibited by proteins known as inhibitors of apoptosis (IAPs). In addition to apoptosis, caspases play a role in necroptosis, pyroptosis, and autophagy, which are non-apoptotic cell death processes. Dysregulation of caspases features prominently in many human diseases, including cancer, autoimmunity, and neurodegenerative disorders, and increasing evidence shows that altering caspase activity can confer therapeutic benefits. This review covers the different types of caspases, their functions, and their physiological and biological activities and roles in different organisms.

    焦亡是程序性细胞死亡的活跃和有序形式。焦亡的信号通路主要分为caspase-1介导的经典通路和caspase-11介导的非经典通路。细胞焦亡的特征是炎性caspase(主要是caspase-1、4、5、11)的激活和Gasdermin家族的各种成员的裂解形成膜穿孔成分,导致细胞膜破裂,炎症介质释放,细胞死亡。中度焦亡是一种抵抗感染的先天免疫反应,在免疫系统正常功能的发生和发展中起重要作用。然而,在许多病理条件下,过度的焦亡会发生并导致免疫紊乱。基于规范路径,对焦亡调节的研究已经证明了几种焦亡抑制剂,包括小分子药物,天然产品,和中药配方。在本文中,我们综述了焦亡的特点和分子机制,总结焦亡抑制剂,并提出中药应成为焦亡阻滞剂研发的重点。
    Pyroptosis is an active and ordered form of programmed cell death. The signaling pathways of pyroptosis are mainly divided into canonical pathways mediated by caspase-1 and noncanonical pathways mediated by caspase-11. Cell pyroptosis is characterized by the activation of inflammatory caspases (mainly caspase-1, 4, 5, 11) and cleavage of various members of the Gasdermin family to form membrane perforation components, leading to cell membrane rupture, inflammatory mediators release, and cell death. Moderate pyroptosis is an innate immune response that fights against infection and plays an important role in the occurrence and development of the normal function of the immune system. However, excessive pyroptosis occurs and leads to immune disorders in many pathological conditions. Based on canonical pathways, research on pyroptosis regulation has demonstrated several pyroptotic inhibitors, including small-molecule drugs, natural products, and formulations of traditional Chinese medicines. In this paper, we review the characteristics and molecular mechanisms of pyroptosis, summarize inhibitors of pyroptosis, and propound that herbal medicines should be a focus on the research and development for pyroptosis blockers.

    缺血性中风(IS)是导致死亡和残疾的主要原因之一。其发病机制尚未完全明确,炎症级联反应是其主要病理过程之一。目前IS的临床实践是通过溶栓治疗尽快恢复IS后缺血区的血供,以保护神经元的活力和功能。然而,血液再灌注进一步加速缺血损伤并引起缺血再灌注损伤。脑缺血再灌注损伤的病理过程涉及多种机制,确切的机制尚未完全阐明。焦亡,一种新发现的炎症程序性细胞死亡形式,在炎症的开始和进展中起着重要作用。它是由caspasecaspase-1/4/5/11介导的促炎程序性死亡,可导致细胞肿胀和破裂,释放炎症因子IL-1β和IL-18,并诱导炎症级联反应。最近的研究表明,焦凋亡及其介导的炎症反应是加重缺血性脑损伤的重要因素,抑制焦亡可以减轻缺血性脑损伤。此外,研究发现,天然植物成分可能对焦亡具有调节作用。因此,本文综述了焦凋亡的分子机制及其在缺血性脑卒中中的作用,以及天然植物成分作为焦亡调节剂的作用,以期为今后IS的治疗提供有关焦亡的参考信息。
    Ischemic stroke (IS) is one of the leading causes of death and disability. Its pathogenesis is not completely clear, and inflammatory cascade is one of its main pathological processes. The current clinical practice of IS is to restore the blood supply to the ischemic area after IS as soon as possible through thrombolytic therapy to protect the vitality and function of neurons. However, blood reperfusion further accelerates ischemic damage and cause ischemia-reperfusion injury. The pathological process of cerebral ischemia-reperfusion injury involves multiple mechanisms, and the exact mechanism has not been fully elucidated. Pyroptosis, a newly discovered form of inflammatory programmed cell death, plays an important role in the initiation and progression of inflammation. It is a pro-inflammatory programmed death mediated by caspase Caspase-1/4/5/11, which can lead to cell swelling and rupture, release inflammatory factors IL-1β and IL-18, and induce an inflammatory cascade. Recent studies have shown that pyroptosis and its mediated inflammatory response are important factors in aggravating ischemic brain injury, and inhibition of pyroptosis may alleviate the ischemic brain injury. Furthermore, studies have found that natural plant components may have a regulatory effect on pyroptosis. Therefore, this review not only summarizes the molecular mechanism of pyroptosis and its role in ischemic stroke, but also the role of natural plant components as regulator of pyroptosis, in order to provide reference information on pyroptosis for the treatment of IS in the future.

    Neurodegenerative disorders (NDs) include Parkinson\'s disease (PD), Alzheimer\'s disease (AD), Huntington\'s disease (HD), and amyotrophic lateral sclerosis (ALS) and the common feature of NDs is the progressive death of specific neurons in the brain. Apoptosis is very important in developing the nervous system, nonetheless an elevated level of cell death has been observed in the case of NDs. NDs are different in terms of their neuronal vulnerability and clinical manifestations, however they have some overlapping neurodegenerative pathways. It has been demonstrated by several studies with cell lines and animal models that apoptosis has a significant contribution to make in advancing AD, ALS, HD, and PD. Numerous dying neurons were also identified in the brains of individuals with NDs and these conditions were found to be linked with substantial cell loss along with common characteristics of apoptosis including activation of caspases and cysteine-proteases, DNA fragmentation, and chromatin condensation. It has been demonstrated that several therapeutic agents including antioxidants, minocycline, GAPDH ligands, p53 inhibitors, JNK (c-Jun N-Terminal Kinase) inhibitors, glycogen synthase kinase-3 inhibitor, non-steroidal anti-inflammatory drugs, D2 dopamine receptor agonists, FK506, cell cycle inhibitors, statins, drugs targeting peroxisome proliferator-activated receptors, and gene therapy have the potential to provide protection to neurons against apoptosis. Therefore, the use of these potential therapeutic agents might be beneficial in the treatment of NDs. In this review, we have summarized the pathways that are linked with apoptotic neuronal death in the case of various NDs. We have particularly focused on the therapeutic agents that have neuroprotective properties and the potential to regulate apoptosis in NDs.

    This systematic review aims to discover the plausible mechanism of Ozone in A.D., to boost translational research. The main focus of our review lies in understanding the effects of ozone pollution on the human brain and causing degenerative disease. Owing to the number of works carried out as preclinical evidence in association with oxidative stress and Alzheimer\'s disease and the lack of systematic review or meta-analysis prompted us to initiate a study on Alzheimer\'s risk due to ground-level ozone. We found relevant studies from PubMed, ScienceDirect, Proquest, DOAJ, and Scopus, narrowing to animal studies and the English language without any time limit. The searches will be re-run before the final analysis. This work was registered in Prospero with Reg ID CRD42022319360, followed the PRISMA-P framework, and followed the PICO approach involving Population, Intervention/Exposure, Comparison, and Outcomes data. Bibliographic details of 16 included studies were studied for Exposure dose of ozone, duration, exposure, and frequency with control and exposure groups. Primary and secondary outcomes were assessed based on pathology significance, and results were significant in inducing Alzheimer-like pathology by ozone. In conclusion, ozone altered oxidative stress, metabolic pathway, and amyloid plaque accumulation besides endothelial stress response involving mitochondria as the critical factor in ATP degeneration, caspase pathway, and neuronal damage. Thus, ozone is a criteria pollutant to be focused on in mitigating Alzheimer\'s Disease pathology.
