Aging Neurosci."],"abstract":"<jats:p>\n                    Neurodegenerative diseases are a group of chronic, progressive disorders characterized by the gradual loss of neurons in specific areas of the central nervous system. Historically, a \u201cneurocentric\u201d paradigm viewed glial cells, such as astrocytes, as cells that provided adequate support for neuronal energy metabolism and controlled local cerebral blood flow. However, studies from the past two decades found that astrocytes are involved in synaptic function through different mechanisms, including the uptake of extracellular glutamate molecules and potassium ions following synaptic neuronal transmission. Also, astrocytes respond to neurotransmitters and neuromodulators through alterations of intracellular ion concentrations (e.g., Na\n                    <jats:sup>+<\/jats:sup>\n                    , Ca\n                    <jats:sup>2+<\/jats:sup>\n                    , K\n                    <jats:sup>+<\/jats:sup>\n                    ) and the release of gliotransmitters. Astrocytes play a pivotal role in preserving potassium homeostasis within the central nervous system through their potassium channels, a process known as \u201cpotassium clearance.\u201d Impaired astrocytic potassium clearance mechanisms can result in neuronal hyperexcitability, leading to increased glutamate release, overactivation of glutamate receptors, and cytotoxicity. Recent studies suggest that these factors can cause cell death and neurodegeneration, and further indicate a region-specific glial dysfunction in neurodegeneration, which reflects the heterogeneity of glial cell function and sensitivity across different brain regions. Overall, this manuscript offers novel insights into a relatively new concept that glial cells can actively shape neuronal activity and survival.\n                  <\/jats:p>","DOI":"10.3389\/fnagi.2026.1782460","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T06:50:48Z","timestamp":1773903048000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Astrocytic K+ regulation during neurodegenerative diseases"],"prefix":"10.3389","volume":"18","author":[{"given":"Evgeniia","family":"Samokhina","sequence":"first","affiliation":[{"name":"Clem Jones Centre for Ageing Dementia Research, Queensland Brain Institute, The University of Queensland","place":["Brisbane, QLD, Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yossi","family":"Buskila","sequence":"additional","affiliation":[{"name":"Laboratory of Cellular neurophysiology, School of Medicine, Western Sydney University","place":["Campbelltown, NSW, Australia"]},{"name":"The MARCS Institute, Western Sydney University","place":["Campbelltown, NSW, Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"56","DOI":"10.1007\/s10571-025-01574-w","article-title":"Astroglial Kir4.1 and AQP4 channels: key regulators of potassium homeostasis and their implications in autism spectrum disorders","volume":"45","author":"Abbasian","year":"2025","journal-title":"Cell.
