HIV-derived TAT peptide, with a high penetration rate into cells and its nonimmunogenic and minimally toxic nature, is an attractive tool for enhancing the biodistribution of drugs and their systemic administration. Despite the presence of numerous promising preclinical investigations illustrating its capability to specifically target distinct tissues and deliver a diverse range of pharmacological agents, the efficacy of various clinical trials incorporating TAT has been impeded by several considerable obstacles. Hence, there is much need for an in-depth investigation concerning the application of TAT in drug delivery mechanisms. In this review, we have elucidated the structure of TAT and its utility in the proficient delivery of various types of bioactive molecules.
艾滋病病毒衍生的 TAT 肽具有较高的细胞渗透率、非免疫原性和毒性小的特点,是增强药物生物分布和全身用药的一种极具吸引力的工具。尽管有大量前景看好的临床前研究表明,TAT 能够特异性地靶向不同的组织,并递送各种药剂,但采用 TAT 进行的各种临床试验的疗效一直受到一些重大障碍的阻碍。因此,亟需对 TAT 在给药机制中的应用进行深入研究。在这篇综述中,我们阐明了 TAT 的结构及其在熟练递送各类生物活性分子方面的作用。

MicroRNA-29b (miR-29b) is known for its therapeutic potential as an antifibrotic and anticancer agent. In fibrotic conditions, miR-29b inhibits fibrogenesis by downregulating crucial regulators such as collagens, extracellular matrix proteins and the transforming growth factor-β pathway. Similarly, in cancer, it acts as a tumor suppressor by downregulating various oncogenes and signaling pathways involved in cancer progression, such as Wnt–β-catenin, p38–mitogen-activated protein kinase and nuclear factor-κB. However, the upregulation of these pathways suppresses miR-29b, contributing to fibrosis and cancer development. Preclinical research and clinical trials have shown that delivering exogenous miR-29b mimics can restore its expression, attenuating tumorigenesis and fibrogenesis. This review discusses miR-29b’s potential and its possible therapeutic development for cancer and fibrotic disorders.
众所周知,MicroRNA-29b(miR-29b)具有抗纤维化和抗癌的治疗潜力。在纤维化条件下,miR-29b 通过下调胶原蛋白、细胞外基质蛋白和转化生长因子-β 通路等关键调节因子来抑制纤维生成。同样,在癌症中,miR-29b 通过下调 Wnt-β-catenin、p38-中性粒细胞活化蛋白激酶和核因子-κB 等参与癌症进展的各种致癌基因和信号通路,起到抑制肿瘤的作用。然而,这些通路的上调会抑制 miR-29b,导致纤维化和癌症发展。临床前研究和临床试验表明,提供外源性miR-29b模拟物可以恢复其表达,从而减轻肿瘤发生和纤维化。本综述将讨论 miR-29b 的潜力及其对癌症和纤维化疾病的可能治疗发展。

Glioblastoma multiforme (GBM) is the most common CNS cancer, it has dismal survival rates despite several effective mediators: intensified cytotoxic therapy, chimeric antigen receptor (CAR)-T cell therapy, viral therapy, adoptive cell therapy, immune checkpoint blockade therapy, radiation therapy and vaccine therapy. This review examines the basic concepts underlying immune targeting and examines products such as checkpoint blockade drugs, CAR-T cells, oncolytic viruses, combinatory multimodal immunotherapy and cancer vaccines. New approaches to overcoming current constraints and challenges in GBM therapy are discussed, based on recent studies into these tactics, findings from ongoing clinical trials, as well as previous trial results.
多形性胶质母细胞瘤(GBM)是最常见的中枢神经系统癌症,尽管有多种有效的治疗手段,如强化细胞毒疗法、嵌合抗原受体(CAR)-T 细胞疗法、病毒疗法、收养细胞疗法、免疫检查点阻断疗法、放射疗法和疫苗疗法,但其生存率仍然很低。这篇综述探讨了免疫靶向的基本概念,并研究了检查点阻断药物、CAR-T 细胞、溶瘤病毒、联合多模式免疫疗法和癌症疫苗等产品。根据对这些策略的最新研究、正在进行的临床试验结果以及以前的试验结果,讨论了克服当前 GBM 治疗中的限制和挑战的新方法。

Osteoarthritis (OA) is an incurable, painful, and debilitating joint disease affecting over 500 million people worldwide. The OA joint tissues are infiltrated by various immune cells, particularly macrophages, which are able to induce or perpetuate inflammation. Notably, synovitis and its macrophage component represent a target of interest for developing treatments. In this review, we describe the latest advances in understanding the heterogeneity of macrophage origins, phenotypes, and functions in the OA joint and the effect of current symptomatic therapies on these cells. We then highlight the therapeutic potential of anticytokines/chemokines, nano- and microdrug delivery, and future strategies to modulate macrophage functions in OA.

Metabolic and transcriptional reprogramming are crucial hallmarks of carcinogenesis that present exploitable vulnerabilities for the development of targeted anticancer therapies. Through controlling the balance of the cellular methionine (MET) metabolite pool, MET adenosyl transferase 2 alpha (MAT2A) regulates crucial steps during metabolism and the epigenetic control of transcription. The aberrant function of MAT2A has been shown to drive malignant transformation through metabolic addiction, transcriptional rewiring, and immune modulation of the tumor microenvironment (TME). Moreover, MAT2A sustains the survival of 5′-methylthioadenosine phosphorylase (MTAP)-deficient tumors, conferring synthetic lethality to cancers with MTAP loss, a genetic alteration that occurs in ∼15% of all cancers. Thus, the pharmacological inhibition of MAT2A is emerging as a desirable therapeutic strategy to combat tumor growth. Here, we review the latest insights into MAT2A biology, focusing on its roles in both metabolic addiction and gene expression modulation in the TME, outline the current landscape of MAT2A inhibitors, and highlight the most recent clinical developments and opportunities for MAT2A inhibition as a novel anti-tumor therapy.
代谢和转录重编程是致癌的关键标志,是开发靶向抗癌疗法的可利用漏洞。通过控制细胞蛋氨酸(MET)代谢物池的平衡,MET腺苷转移酶2α(MAT2A)调节着代谢过程中的关键步骤和转录的表观遗传控制。研究表明,MAT2A 的异常功能可通过代谢成瘾、转录重构和肿瘤微环境(TME)的免疫调节来驱动恶性转化。此外,MAT2A 能维持 5'-methylthioadenosine phosphorylase(MTAP)缺失肿瘤的存活,使 MTAP 缺失的癌症具有合成致死性,这种基因改变发生在所有癌症中的 15%。因此,对 MAT2A 的药理抑制正逐渐成为对抗肿瘤生长的理想治疗策略。在此,我们回顾了对 MAT2A 生物学的最新见解,重点关注其在 TME 中代谢成瘾和基因表达调控方面的作用,概述了 MAT2A 抑制剂的现状,并着重介绍了 MAT2A 抑制剂作为一种新型抗肿瘤疗法的最新临床进展和机遇。

The use of proteomics in human studies investigating stroke and myocardial infarction (MI) has been increasing, prompting a review of the literature. This revealed proteinaceous biomarkers of stroke from thrombi, brain tissue, cells, and particles, some of which cross the blood–brain barrier (BBB). Several proteins were also implicated in coronary artery disease (CAD), which often underlies MI, cholesterol transportation, and inflammation. Furthermore, the platelet proteome revealed itself as a potential therapeutic target, along with differentially expressed proteins associated with MI progression. Moreover, proteomic data enhanced the performance of conventional risk scores and causal protein discovery has improved interventions and drug development for patients with MI and other conditions. These findings suggest that proteomics holds much promise for future stroke and MI research.
在调查中风和心肌梗塞(MI)的人体研究中,蛋白质组学的应用越来越多,这促使我们对文献进行了回顾。这揭示了来自血栓、脑组织、细胞和微粒的中风蛋白质生物标志物,其中一些可以穿过血脑屏障(BBB)。一些蛋白质还与冠状动脉疾病(CAD)有关,而冠状动脉疾病往往是心肌梗死、胆固醇运输和炎症的基础。此外,血小板蛋白质组以及与心肌缺血进展相关的差异表达蛋白质也显示出血小板是一个潜在的治疗靶点。此外,蛋白质组数据提高了传统风险评分的性能,因果蛋白的发现改善了对心肌梗死和其他疾病患者的干预和药物开发。这些发现表明,蛋白质组学在未来的中风和心肌梗死研究中大有可为。

Molecularly imprinted polymers (MIPs) are polymeric matrices that can mimic natural recognition entities, such as antibodies and biological receptors. Molecular imprinting of therapeutics is very appealing in the design of drug delivery systems since the specific and selective binding sites created within the polymeric matrix turn these complex structures into value-added carriers with tunable features, notably high drug-loading capacity and good control of payload release. MIPs possess considerable promise as synthetic recognition elements in ‘theranostics’. Moreover, the high affinity and specificity of MIPs make them more advantageous than other polymer-based nanocomposites. This review summarizes the present state-of-the-art of MIP-based delivery systems for the targeted delivery of bioactives, with current challenges and future perspectives.
分子印迹聚合物(MIPs)是一种聚合物基质,可以模拟抗体和生物受体等天然识别实体。治疗药物的分子印迹在药物输送系统的设计中非常有吸引力,因为在聚合物基质中创建的特异性和选择性结合位点可将这些复杂结构转化为具有可调特性的增值载体,特别是高药物负载能力和有效载荷释放的良好控制。作为 "治疗学 "中的合成识别元件,MIPs 具有广阔的前景。此外,MIPs 的高亲和性和特异性使其比其他聚合物基纳米复合材料更具优势。本综述总结了目前基于 MIP 的定向输送生物活性物质的输送系统的最新进展,以及当前面临的挑战和未来展望。

Diabetes is a complex, multifactorial disease that is caused by a pathological combination of insulin resistance and pancreatic islet dysfunction. Polysaccharides are extensively dispersed in nature and have a very complicated structure with various biological properties. Natural polysaccharides have potentially extraordinary beneficial health effects on managing metabolic diseases such as diabetes, obesity and cardiovascular disease. Thus, a systematic review of the latest research into and possible regulatory mechanisms of natural polysaccharides for type 2 diabetes mellitus treatment is of great significance for a better understanding of their pharmaceutical value. We discuss the regulatory mechanisms of natural polysaccharides for the treatment of diabetes, and especially their role in reshaping dysfunctional gut microbiota. Natural polysaccharides could be developed as new and safe antidiabetic drugs, and detailed mechanistic studies could further clarify the molecular targets of polysaccharides in the treatment of diabetes.
糖尿病是一种复杂的多因素疾病,由胰岛素抵抗和胰岛功能障碍的病理组合引起。多糖广泛分布于自然界中,具有非常复杂的结构和各种生物特性。天然多糖对控制糖尿病、肥胖症和心血管疾病等代谢性疾病具有非凡的潜在保健作用。因此,对天然多糖治疗 2 型糖尿病的最新研究和可能的调控机制进行系统综述,对于更好地了解天然多糖的医药价值具有重要意义。我们讨论了天然多糖治疗糖尿病的调节机制,特别是其在重塑功能失调的肠道微生物群方面的作用。天然多糖可开发为安全的新型抗糖尿病药物,详细的机理研究可进一步阐明多糖治疗糖尿病的分子靶点。

Polysaccharides are extensively dispersed in nature and have a very complicated structure with various biological properties. Natural polysaccharides have potentially extraordinary beneficial health effects on managing metabolic diseases such as diabetes, obesity and cardiovascular disease. Thus, a systematic review of the latest research into and possible regulatory mechanisms of natural polysaccharides for type 2 diabetes mellitus treatment is of great significance for a better understanding of their pharmaceutical value. We discuss the regulatory mechanisms of natural polysaccharides for the treatment of diabetes, and especially their role in reshaping dysfunctional gut microbiota.
