Extracellular vesicles in host-parasite interactions: a bibliometric review of mechanisms, diagnostics, vaccines, and drug delivery (2015-2025)
Abstract
Extracellular vesicles (EVs) derived from parasites have emerged as a critical frontier for understanding pathogenic mechanisms and developing novel control strategies. This bibliometric analysis systematically examines 365 original research articles published between 2015 and 2025 using CiteSpace to map the intellectual structure, collaborative networks, and evolving research hotspots of this field. Global publication output exhibits a sustained upward trend, with China, the United States, Brazil, Spain, and Australia as the leading contributors. Notably, Spain demonstrates the highest centrality in international collaboration networks, functioning as a key hub. Author co-authorship analysis reveals a relatively sparse network density, with Ana Claudia Torrecilhas, Alex Loukas, and Antonio Marcilla among the most prolific contributors. Keyword clustering using the log-likelihood ratio algorithm identifies three predominant research domains: protozoan parasites (encompassing Plasmodium, Trypanosoma, Leishmania, and Toxoplasma), trematode parasites (including Schistosoma and Fasciola), and cellular/molecular mechanisms of immunomodulation. Timeline analysis documents a decisive paradigm shift from morphological description and cargo cataloguing toward mechanistic dissection of host-parasite crosstalk, with increasing emphasis on translational applications in diagnostics, vaccine development, and drug delivery. Burst detection analysis reveals sustained citation bursts for…
