Background: In recent years, numerous reports have been published regarding the relationship between the gut microbiota and the tumor immune microenvironment (TIME). However, to date, no systematic study has been conducted on the relationship between gut microbiota and the TIME using bibliometric methods.
Aim: To describe the current global research status on the correlation between gut microbiota and the TIME, and to identify the most influential countries, research institutions, researchers, and research hotspots related to this topic.
Methods: We searched for all literature related to gut microbiota and TIME published from January 1, 2014, to May 28, 2024, in the Web of Science Core Collection database. We then conducted a bibliometric analysis and created visual maps of the published literature on countries, institutions, authors, keywords, references, using CiteSpace (6.2R6), VOSviewer (1.6.20), and bibliometrics (based on R 4.3.2).
Results: In total, 491 documents were included, with a rapid increase in the number of publications starting in 2019. The country with the highest number of publications was China, followed by the United States. Germany has the highest number of citations in literature. From a centrality perspective, the United States has the highest influence in this field. The institutions with the highest number of publications were Shanghai Jiao Tong University and Zhejiang University. However, the institution with the most citations was the United States National Cancer Institute. Among authors, Professor Giorgio Trinchieri from the National Institutes of Health has the most local impact in this field. The most cited author was Fan XZ. The results of journal publications showed that the top three journals with the highest number of published papers were and The three most frequently used keywords were gut microbiota, tumor microenvironment, and immunotherapy.
Conclusion: This study systematically elaborates on the research progress related to gut microbiota and TIME over the past decade. Research results indicate that the number of publications has rapidly increased since 2019, with research hotspots including "gut microbiota", "tumor microenvironment" and "immunotherapy". Exploring the effects of specific gut microbiota or derived metabolites on the behavior of immune cells in the TIME, regulating the secretion of immune molecules, and influencing immunotherapy are research hotspots and future research directions.

Ulcerative colitis (UC) is a chronic, nonspecific inflammatory disorder characterized by symptoms such as abdominal pain, diarrhea, hematochezia, and urgency during defecation. While the primary site of involvement is the colon, UC can extend to encompass the entire rectum and colon. The causes and development mechanisms of UC are still not well understood; nonetheless, it is currently held that factors including environmental influences, genetic predispositions, intestinal mucosal integrity, gut microbiota composition, and immune dysregulation contribute to its development.

In recent years, tumor immunotherapy has made significant breakthroughs in the treatment of malignant tumors. However, individual differences in efficacy have been observed in clinical practice. There is increasing evidence that gut microbial metabolites influence the efficacy of distal tumor immunotherapy via the gut-liver axis, the gut-brain axis and the gut-breast axis, a process that may involve modulating the expression of immune cells and cytokines in the tumor microenvironment (TME).

Background: Liver fibrosis is characterized by hepatic stellate cell (HSC) activation and collagen overproduction, but its pathogenesis remains largely unknown. This study aimed to uncover the role of neural precursor cell expressed developmentally downregulated 4-like (Nedd4L) signaling in liver fibrosis and its relationship with gut microbiota.
Methods: Intraperitoneal injection of carbon tetrachloride (CCl) was used to induce liver fibrosis in 8-week-old female C57BL/6J mice with knockout or administration of the Nedd4L protein phosphorylation inhibitor EMD638683.

The COVID-19 pandemic underscored bacterial resistance as a critical global health issue, exacerbated by the increased use of antibiotics during the crisis. Notwithstanding the pandemic's prevalence, initiatives to address bacterial medication resistance have been inadequate. Although an overall drop in worldwide antibiotic consumption, total usage remains substantial, requiring rigorous regulatory measures and preventive activities to mitigate the emergence of resistance.
