摘要
背景:轴突在神经系统与身体其他部分的连接中起着至关重要的作用。轴突病变通常会导致运动和认知功能以及与外界相互作用的永久性损害。轴突再生的研究已成为一个备受关注的研究领域。本研究的目的是获得轴突再生研究领域的整体视角,并帮助研究人员和资助机构更好地了解最大的研究机会领域。方法:对近22年来基于Web of Science (WoS)的全球轴突再生相关文献进行文献计量学分析和潜狄利克雷分配(Latent Dirichlet Allocation, LDA)分析,找出轴突再生的研究热点、发表趋势和研究不足。结果:共纳入文献21,018篇,近20年来增长了125%。在前12大热点中,轴突再生信号通路、轴突引导线索、神经回路与功能恢复、神经导管、细胞移植等课题的年度产量快速增长。相比之下,轴突再生抑制剂的研究数量减少了。关于神经移植的主题,每年的论文数量趋于稳定。然而,轴突再生的潜在机制尚未完全揭示。在表观遗传程序和非编码rna调控方面的研究较少。细胞类型特异性数据的重要性已经得到强调,但在这方面的研究有限。神经病变的功能恢复也需要进一步的研究。结论:近二十年来,轴突再生研究取得了巨大进展。在将这些技术转化为临床实践方面仍有许多挑战需要解决。
Research hotspots and trends for axon regeneration (2000-2021): a bibliometric study and systematic review.
Background: Axons play an essential role in the connection of the nervous system with the rest of the body. Axon lesions often lead to permanent impairment of motor and cognitive functions and the interaction with the outside world. Studies focusing on axon regeneration have become a research field with considerable interest. The purpose of this study is to obtain an overall perspective of the research field of axonal regeneration and to assist the researchers and the funding agencies to better know the areas of greatest research opportunities.
Methods: We conducted a bibliometric analysis and Latent Dirichlet Allocation (LDA) analysis of the global literature on axon regeneration based on the Web of Science (WoS) over the recent 22 years, to address the research hotspots, publication trends, and understudied areas.
Results: A total of 21,018 articles were included, which in the recent two decades has increased by 125%. Among the top 12 hotspots, the annual productions rapidly increased in some topics, including axonal regeneration signaling pathway, axon guidance cues, neural circuits and functional recovery, nerve conduits, and cells transplant. Comparatively, the number of studies on axon regeneration inhibitors decreased. As for the topics focusing on nerve graft and transplantation, the annual number of papers tended to be relatively stable. Nevertheless, the underlying mechanisms of axon regrowth have not been completely uncovered. A lack of notable research on the epigenetic programs and noncoding RNAs regulation was observed. The significance of cell-type-specific data has been highlighted but with limited research working on that. Functional recovery from neuropathies also needs further studies.
Conclusion: The last two decades witnessed tremendous progress in the field of axon regeneration. There are still a lot of challenges to be tackled in translating these technologies into clinical practice.
期刊介绍:
Inflammation and Regeneration is the official journal of the Japanese Society of Inflammation and Regeneration (JSIR). This journal provides an open access forum which covers a wide range of scientific topics in the basic and clinical researches on inflammation and regenerative medicine. It also covers investigations of infectious diseases, including COVID-19 and other emerging infectious diseases, which involve the inflammatory responses.
Inflammation and Regeneration publishes papers in the following categories: research article, note, rapid communication, case report, review and clinical drug evaluation.
