Abstract

Stroke remains a leading cause of global disability, perpetuated by maladaptive neuroinflammation that drives secondary injury and impairs recovery. An early reparative (M2) state rapidly transitions into a dominant destructive (M1) phenotype within days, worsening tissue damage through the release of cytokines [tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6)], blood-brain barrier disruption, and amplified peripheral immune cell infiltration. Emerging pharmacological interventions, such as the free radical scavenger edaravone, the neurotrophic factor cerebrolysin, and the excitotoxicity modulator citicoline, demonstrate promising neuroprotective potential when strategically timed. Additionally, novel non-pharmacological approaches, including repetitive transcranial magnetic stimulation, stem cell therapy, and nanoparticle-based drug delivery, offer innovative pathways for targeting neuroinflammation. However, translational challenges persist, including narrow therapeutic windows, biomarker heterogeneity, and preclinical-to-clinical gaps. Future progress necessitates precision medicine paradigms integrating spatiotemporal drug delivery, biomarker-guided intervention timing, and synergistic combinatorial regimens targeting acute injury and chronic repair phases. By bridging mechanistic insights with clinical applications, this review delineates neuroinflammatory modulation as a pivotal frontier for redefining stroke recovery while outlining essential research trajectories to overcome existing barriers. Systematic search of electronic databases including PubMed, Web of Science, Embase, and Cochrane (1996-2025) was performed, with eligible studies assessed using PRISMA guidelines. Findings on neuroinflammation, mechanism, or interventions in ischemic stroke were narratively synthesized through thematic analysis. This review summarizes current insights into post-stroke neuroinflammatory mechanisms, with a focus on the dual role of microglial polarization.

脑卒中后神经炎症的小胶质细胞极化和治疗策略。

中风仍然是全球致残的主要原因，由于不适应的神经炎症导致继发性损伤和损害恢复。早期的修复（M2）状态在几天内迅速转变为显性的破坏性（M1）表型，通过细胞因子[肿瘤坏死因子α (TNFα)，白细胞介素6 (IL-6)]的释放，血脑屏障破坏和外周免疫细胞浸润的扩大而加剧组织损伤。新兴的药物干预，如自由基清除剂依达拉奉、神经营养因子脑溶血素和兴奋毒性调节剂胞胆碱，在适当的时机显示出有希望的神经保护潜力。此外，新的非药物方法，包括重复经颅磁刺激、干细胞治疗和基于纳米颗粒的药物递送，为靶向神经炎症提供了创新的途径。然而，翻译方面的挑战仍然存在，包括狭窄的治疗窗口、生物标志物异质性和临床前与临床之间的差距。未来的进展需要整合时空药物递送、生物标志物引导的干预时机以及针对急性损伤和慢性修复阶段的协同组合方案的精准医学范式。通过将机制见解与临床应用相结合，本综述将神经炎症调节描述为重新定义卒中恢复的关键前沿，同时概述了克服现有障碍的基本研究轨迹。对PubMed、Web of Science、Embase和Cochrane（1996-2025）等电子数据库进行系统检索，使用PRISMA指南对符合条件的研究进行评估。通过专题分析，对缺血性脑卒中的神经炎症、机制或干预措施的研究结果进行了叙述性的综合。这篇综述总结了目前对脑卒中后神经炎症机制的见解，重点是小胶质细胞极化的双重作用。

期刊介绍： Aims and Scope Neurology and Therapy aims to provide reliable and inclusive, rapid publication for all therapy related research for neurological indications, supporting the timely dissemination of research with a global reach, to help advance scientific discovery and support clinical practice. Neurology and Therapy is an international, open access, peer reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world and health outcomes research around the discovery, development, and use of neurological and psychiatric therapies, (also covering surgery and devices). Studies relating to diagnosis, pharmacoeconomics, public health, quality of life, and patient care, management, and education are also welcomed. The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, case reports, trial designs, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Neurology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research. Rapid Publication The journal’s rapid publication timelines aim for a peer review decision within 2 weeks of submission. If an article is accepted, it will be published online 3-4 weeks from acceptance. These rapid timelines are achieved through the combination of a dedicated in-house editorial team, who closely manage article workflow, and an extensive Editorial and Advisory Board who assist with rapid peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model, this allows for the rapid and efficient communication of the latest research and reviews to support scientific discovery and clinical practice. Open Access All articles published by Neurology and Therapy are open access. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning that authors will always have a personal point of contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. We also encourage pre-submission enquiries and are always happy to provide a confidential assessment of manuscripts. Digital Features and Plain Language Summaries Neurology and Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of an article, authors will be required to pay the mandatory Rapid Service Fee of €5250/$6000/£4300. The journal will consider fee discounts and waivers for developing countries and this is decided on a case-by-case basis. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials and Letters which are generally reviewed by one member of the Editorial Board. Where reviews conflict, an Editorial Board Member will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed. Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised, it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case-by-case basis and should be sent to the journal editor, and authors are welcome to make rebuttals against individual reviewer comments, if appropriate. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors'' or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals.
