ABSTRACT
AMPA receptors (AMPARs) are critical excitatory ionotropic glutamate receptors involved in synaptic transmission, plasticity, and various neurological disorders. From 2000 to present (up to 2025), extensive research has explored their roles in brain function and disease, yet a comprehensive bibliometric analysis of this field is lacking. This study aims to provide a systematic bibliometric overview of AMPAR research from 2000 to present, identifying key trends, influential contributors, and emerging hotspots to guide future investigations. Data were retrieved from Web of Science, PubMed, and Scopus, encompassing 37,000 distinct publications. Bibliometric tools (CiteSpace, VOSviewer, and Bibliometrix) were employed to analyze publication trends, country/institution contributions, journal metrics, author productivity, and keyword clusters. The United States led in publication output (6,142 articles) and citations (410,626), followed by China and Japan. The Journal of Neuroscience and Neuron were the top journals, while Huganir RL was the most cited author. Research hotspots evolved from fundamental AMPAR properties (e.g., subunit composition) to disease associations (e.g., Alzheimer’s, depression) and therapeutic strategies (e.g., AMPAR modulators). Keyword analysis revealed four themes: biochemical properties, physiological functions, pathological roles, and therapeutic targets. AMPAR research has transitioned from basic neurophysiology to translational applications, with growing emphasis on neurological and psychiatric disorders. Future directions include elucidating native AMPAR complexes, trafficking dynamics, and precision therapeutics. This study highlights the field’s progression and underscores the need for interdisciplinary collaboration to address unresolved challenges.
