The core pathological feature of AD is an imbalance in A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    production and clearance, leading to conformational changes and pathological aggregation of A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    peptides. This imbalance triggers neurodegenerative cascades 20\u201330\u202fyears before clinical symptoms appear. Therapeutic approaches targeting A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    production, including\n                    <jats:italic>\u03b2<\/jats:italic>\n                    -secretase and\n                    <jats:italic>\u03b3<\/jats:italic>\n                    -secretase inhibitors, have thus far shown limited clinical benefit in late-stage trials and have been further constrained by safety and tolerability concerns. As a result, early interventions aimed at enhancing A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    clearance have attracted increasing attention. While microglia-mediated phagocytosis of A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    has been extensively studied, the multifaceted roles of astrocytes in this process remain underexplored. This review synthesizes recent findings to elucidate the molecular mechanisms of astrocyte-mediated A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    clearance, focusing on endocytic uptake and intracellular degradation, maintenance of the blood\u2013brain barrier, and aquaporin-4 (AQP4)-dependent glymphatic drainage. Additionally, this review dissects key regulatory nodes, including the dynamic modulation of A\n                    <jats:italic>\u03b2<\/jats:italic>\n                    clearance capacity through astrocyte phenotypic transitions and functional decline associated with pathology. These insights offer a theoretical foundation and translational perspective for the development of astrocyte-targeted interventions in early-stage AD.\n                  <\/jats:p>","DOI":"10.3389\/fnins.2026.1812081","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T04:48:03Z","timestamp":1778129283000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Amyloid-\u03b2 clearance: an astrocytic perspective"],"prefix":"10.3389","volume":"20","author":[{"given":"Jiayi","family":"Li","sequence":"first","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongyue","family":"Lv","sequence":"additional","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fan","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaixia","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guogang","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"Ningbo Institute of Innovation for Combined Medicine and Engineering (NIIME), The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guomin","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Neurology, The Affiliated Lihuili Hospital of Ningbo University, Ningbo University","place":["Ningbo, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,5,7]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"62","DOI":"10.1038\/s41586-019-1419-5","article-title":"Meningeal lymphatic vessels at the skull base drain cerebrospinal fluid","volume":"572","author":"Ahn","year":"2019","journal-title":"Nature"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"30406","DOI":"10.1074\/jbc.M414686200","article-title":"Expression of scavenger receptors in glial cells.
