Macrophages-Mediated Liver Fibrosis: A Bibliometric Analysis

Abstract

Background: Macrophages play a significant role in both the development and regression of liver fibrosis, engaging in related pro-inflammatory and anti-inflammatory processes. In recent years, an increasing number of studies have elucidated the mechanisms by which macrophages influence liver fibrosis. Objectives: This bibliometric analysis aims to investigate the research trends in liver fibrosis regulation by macrophages through a systematic literature review. Methods: We conducted a search for literature, including research articles and reviews, using the keywords 'liver fibrosis and macrophages' and 'liver cirrhosis and macrophages' in the Web of Science database, covering the period from 2007 to 2023. We retrieved and analyzed publications on liver fibrosis mediated by macrophages from the Web of Science Core Collection database on October 8, 2023. Visualization analysis was performed using CreateSpace (version 6.1.R6), VOSviewer (version 1.6.19), and Scimago Graphica (version 1.0.34.0). Results: We identified a total of 1732 records in the WoSCC, of which 1664 papers were ultimately included in our analysis. China emerged as the country with the most significant number of publications, while Germany and the University of California San Diego stood out for their influence, with centralities of 0.41 and 0.14, respectively. Frank Tacke was identified as the most prolific author, contributing 49 papers. Hepatology was the journal with the highest number of publications and citations. The most frequently mentioned keywords in this field were liver fibrosis, expression, hepatic stellate cells, activation, inflammation, and macrophages. Conclusions: The study of macrophage-mediated liver fibrosis, particularly the mechanisms regulating the heterogeneity of hepatic macrophages, is a mature and promising research area. Macrophage-based therapies for liver fibrosis are anticipated to be crucial topics in the future. Bibliometric analysis offers valuable insights for future basic research directions and clinical practice.
