Electrospun proliposomes are an innovative solid-state drug delivery approach in which amphiphilic nanofibers, composed of a hydrophilic polymer, phospholipids, and therapeutic agent(s), are fabricated via electrospinning. These nanofibers stabilize lipids in a dry matrix and spontaneously self-assemble into nanoscale liposomes upon hydration. The integration of liposomes with electrospun nanofibrous scaffolds represents an innovative approach, creating a synergistic nanoscale drug delivery system that combines the complementary advantages of both liposomal and nanofiber technologies. The templating effect of nanofibers, combined with polymer carriers, enhances stability, facilitates the dispersion of therapeutic agent(s), and enables on-demand liposome formation. This opinion article highlights the principles of the in situ proliposome method and the advantages, therapeutic applications, challenges, and opportunities of electrospun proliposomes, positioning them in the broader quest to overcome liposome instability.

Inflammatory bowel diseases (IBDs) are chronic disorders affecting the gastrointestinal tract, causing severe inflammation and tissue damage. Current treatments often have adverse effects, underscoring the need for alternatives. This article is a short review of host defense peptides (HDPs), which have emerged as promising candidates for IBDs because of their antimicrobial and immunomodulatory properties. The HDPs cited include cathelicidins [e.g. LL-37-Tα1, lipid transfer protein (LTP), C-L, KR-12], defensins [e.g. human alpha defensin 5 (HD-5), human beta-defensin 2 (hBD2)], cecropins (e.g. CC34), microcins [e.g. microcin J25 (MccJ25)], brevinins (e.g. chensinin-1), proline-rich antimicrobial peptides (PrAMPs) (e.g. abaecin), type V peptides [e.g. vasopressin–neurophysin (VP–NP)], and alpha-melanocyte-stimulating hormone (α-MSH) (e.g. KPV). HDPs have immunoregulatory mechanisms, downregulating the nuclear factor kappa B (NF-κB) pathway, modulating cytokine release, and restoring homeostasis. The data suggest that HDPs have therapeutic potential for IBDs, offering a way to reduce side effects, and we focus on this issue here.

炎症性肠病（IBDs）是影响胃肠道的慢性疾病，引起严重的炎症和组织损伤。目前的治疗方法往往有副作用，强调需要替代方案。宿主防御肽（host defense peptide, hdp）因其抗菌和免疫调节特性而成为ibd治疗的候选药物。引用的HDPs包括抗菌肽[如LL-37-Tα1，脂质转移蛋白（LTP）， C-L, KR-12]，防御素[如人α-防御素5 (HD-5)，人β -防御素2 (hBD2)]，抗菌肽（如CC34），微霉素[如微霉素J25 (MccJ25)], brevinins（如chensinin-1），富含脯氨酸的抗菌肽（PrAMPs）（如abaecin）， V型肽[如抗利尿素-神经physin (VP-NP)]和α-黑色素细胞刺激激素（α-MSH）（如KPV）。HDPs具有免疫调节机制，下调核因子κB （NF-κB）通路，调节细胞因子释放，恢复体内平衡。数据表明，HDPs具有治疗ibd的潜力，提供了一种减少副作用的方法，我们在这里关注这个问题。

Ferroptosis is an iron-dependent mode of cell death that is driven by phospholipid peroxides. Ferroptosis inducers (FINs) are a new paradigm in cancer treatment as several therapy-resistant cancer cells are sensitive to ferroptosis. System x_c⁻ and glutathione peroxidase 4 (GPX4) are two predominant targets of FINs. Although GPX4 inhibitors prevent the reduction of lipid peroxides, system x_c⁻ inhibitors block glutathione biosynthesis and indirectly inhibit GPX4. In this review, we provide an updated summary of GPX4 and system x_c⁻ inhibitors, as well as GPX4 degraders. We also discuss the shortcomings that impede the clinical success of these FINs for cancer treatment.

铁下垂是一种由磷脂过氧化物驱动的铁依赖性细胞死亡模式。铁下垂诱导剂（FINs）是一种新的癌症治疗模式，因为一些治疗耐药的癌细胞对铁下垂敏感。系统xc-和谷胱甘肽过氧化物酶4 （GPX4）是FINs的两个主要靶点。虽然GPX4抑制剂阻止脂质过氧化物的还原，但系统xc-抑制剂阻断谷胱甘肽的生物合成并间接抑制GPX4。在这篇综述中，我们提供了GPX4和系统xc-抑制剂以及GPX4降解剂的最新综述。我们还讨论了阻碍这些FINs用于癌症治疗的临床成功的缺点。

Emerging and re-emerging RNA viruses continue to challenge global health preparedness, underscoring the need for broad-spectrum antivirals that can be rapidly deployed. We propose a family-specific antiviral design strategy that targets conserved replication–transcription complexes (RTCs) using nanobodies delivered as mRNA therapeutics. This approach overcomes the long-standing limitation of intracellular delivery of antibody-based biologics. By expressing antiviral nanobodies directly inside infected cells via lipid-nanoparticle-encapsulated mRNA, it becomes possible to disrupt essential protein–protein interactions within viral RTCs. Using SARS-CoV-2 non-structural protein 9 (NSP9) as a proof-of-concept, we show that stabilizing non-functional NSP9 oligomers can inhibit viral replication. This combined nanobody–mRNA technology provides a versatile platform for rapid antiviral development across virus families.

新出现和再出现的RNA病毒继续对全球卫生准备工作构成挑战，强调需要能够迅速部署的广谱抗病毒药物。我们提出了一种家族特异性抗病毒设计策略，该策略使用纳米体作为mRNA疗法递送，靶向保守复制转录复合物（rtc）。这种方法克服了基于抗体的生物制剂在细胞内递送的长期限制。通过脂质纳米颗粒包裹的mRNA直接在感染细胞内表达抗病毒纳米体，可以破坏病毒rtc内必需的蛋白质-蛋白质相互作用。利用SARS-CoV-2非结构蛋白9 （NSP9）作为概念验证，我们发现稳定非功能NSP9低聚物可以抑制病毒复制。这种纳米体- mrna联合技术为跨病毒家族快速开发抗病毒药物提供了一个通用平台。

Dysfunction of histone deacetylases (HDACs) is linked to oncogenesis and progression. The expression of classical HDACs varies across different cancers. In some cancers, isozymes of one HDAC class are overactive, whereas in others, multiple classes are involved. HDAC inhibitors (HDACi), which are promising cancer therapeutics, fine-tune the aberrant behaviour of HDACs. These inhibitors are either selective or pan-inhibitors, and it is uncertain which type is the most suitable for treatment. Herein, the optimal solution to this ambiguity is provided based on solid evidence. We suggest that the HDAC overexpression pattern in a specific cancer is key to choosing the optimal therapeutic regimen.

组蛋白去乙酰化酶（hdac）功能障碍与肿瘤的发生和进展有关。经典hdac的表达在不同的癌症中有所不同。在一些癌症中，一类HDAC同工酶过度活跃，而在另一些癌症中，涉及多种HDAC同工酶。HDAC抑制剂（HDACi）是一种很有前途的癌症治疗药物，可以微调HDAC的异常行为。这些抑制剂要么是选择性抑制剂，要么是泛抑制剂，目前还不确定哪种类型最适合治疗。在此，基于确凿的证据给出了这种模糊性的最优解。我们认为，特定癌症中的HDAC过表达模式是选择最佳治疗方案的关键。

Membrane curvature is a fundamental biophysical property that regulates the spatial organization, conformation and function of membrane-associated proteins, playing a crucial part in cellular signaling, material transport and membrane remodeling. Recent advances in imaging and computational technologies have deepened our understanding of the mechanisms driving membrane curvature and its influence on membrane protein function. In this review, we explore the key determinants of membrane curvature, its influence on the structure, function, localization, aggregation and dissociation of membrane proteins, and the experimental and computational strategies employed to investigate these interactions. Additionally, we discuss the therapeutic potential of targeting membrane curvature for disease treatment and outline current challenges and future research directions.

Left ventricular assist devices (LVADs) support patients with end-stage heart failure, yet myocardial recovery and device explant remains rare because of persistent cardiac fibrosis. This review examines the integration of molecular mechanisms and highlights therapeutic targets emerging from clinical and preclinical studies, with a focus on mechanisms that differentiate responders from non-responders. Key pathways include extracellular matrix remodeling, fibroblast activation, cellular plasticity, endothelial-to-mesenchymal transition, immune modulation, and post-transcriptional regulation via alternative polyadenylation. Advancing these mechanistic insights could enable biomarker-driven strategies to overcome the current barriers to improving recovery rates in patients supported by LVADs.

Value can be introduced into the clinical drug development process by increasing the probability of success, and through product differentiation. Quality-by-design tools, expected in formulation optimization, are not common in trial design and program optimization. In this paper, I spotlight recent efforts to incorporate these methods and make suggestions for value-driven clinical development. Value-driven product development is introduced by noting the earlier history outside the pharmaceutical sector. A description of innovations in trial design and program structure highlights the recent focus on inserting value into the drug development process. Shrewdly designed trials can provide higher-quality data with fewer subjects and resources, a timelier basis, and more value for companies. There is a value in planning: plan for value.

Autophagy is an intracellular degradation and recycling mechanism, crucial for maintaining cellular homeostasis. In recent years, the dual role of protein kinases in autophagy has gradually been elucidated. Designing small-molecule compounds to regulate these targets can actively or passively intervene in cell-protective autophagy or autophagy-related cell death. This approach could provide new clues for modern targeted cancer therapies. In this review, we focus on summarizing the regulatory roles of key protein kinases in autophagy, including positive regulation, negative regulation and bidirectional regulation of autophagy. Moreover, we explore the anticancer potential of small-molecule compounds targeting these kinases in cancer therapy, providing new clues for precise treatment by regulating autophagy pathways.
