Abstract

Peripheral nerve injury (PNI) disrupts nerve function, there has been increasing focus on the role of macrophages in PNI. This study provides a comprehensive analysis of research trends and key topics related to macrophages in the field of PNI. We conducted a search in the Web of Science Core Collection database for studies published between 2000 and 2023 using "macrophages" and "PNI" as keywords. Bibliometric analysis was performed using visualization tools, including VOSviewer, CiteSpace, and GraphPad Prism 8, and others. As of December 31, 2023, a total of 905 relevant publications were identified. In terms of author contributions, Japanese researchers Kiguchi Norikazu and Kishioka Shiroh shared the highest number of publications, each with 15 articles. In terms of journals, Experimental Neurology published the most articles, while the University of Würzburg in Germany emerged as the leading institution in this field, with the highest publication output. Among the 51 countries involved in this research, the United States ranked first, followed by China. The keyword 'exosomes' first appeared in 2021, making it the most recent keyword. Cluster analysis categorized the keywords into four main groups: the role of macrophages in Wallerian degeneration, the role of macrophages in pathological peripheral neuropathic pain, macrophage-derived products after PNI, and role of macrophages in PNI repair and strategies for modulating their function using biomaterials. Macrophages are increasingly crucial in PNI research, and future studies integrating novel approaches may yield innovative therapies for nerve repair.
