Astrocytes: Anatomy, Location, and Function - Verywell Health
2023年10月12日 · Function. Astrocytes have a variety of functions within the brain and central nervous system as a whole. Astrocytes provide nutrients to neurons while maintaining the balance between cellular ions such as sodium chloride, potassium, and phosphate.
Astrocyte - Wikipedia
Astrocytes (from Ancient Greek ἄστρον, ástron, "star" and κύτος, kútos, "cavity", "cell"), also known collectively as astroglia, are characteristic star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical control of endothelial cells that form the blood–brain barrier, [1] provision ...
Function and therapeutic value of astrocytes in neurological …
2022年2月16日 · Astrocytes regulate glutamate and ion homeostasis, cholesterol and sphingolipid metabolism and respond to environmental factors, all of which have been implicated in neurological...

2023年5月1日 · Astrocytes are a subtype of glial cells that make up the majority of cells in the human central nervous system (CNS). They perform metabolic, structural, homeostatic, and neuroprotective tasks such as clearing excess neurotransmitters, stabilizing and regulating the blood-brain barrier, and promoting synapse formation.

2023年10月30日 · Astrocytes are the largest and most abundant type of supporting (glial) cells in the central nervous system (CNS). Together with oligodenrocytes they make up a group of glial cells called macroglia, which originate within the neural plate.
Astrocytes: Role and Functions in Brain Pathologies - PMC
One of the most important astrocytes function is to deliver energy to neurons by the astrocyte-neuron lactate shuttle (Bass et al., 1971; Sherwood et al., 2006). Astrocytes modulate Ca 2+ variations that influence neuronal activity releasing gliotransmitters (Peteri et al., 2019).
Astrocytes: The Housekeepers and Guardians of the CNS
Astrocytes perform every known housekeeping and homeostatic function in the CNS from structural support and control over molecular homeostasis to regulation of blood flow, synaptogenesis, neurogenesis and development of the nervous system.
Role of Astrocytes in Brain Function and Disease - PMC
Astrocytes play a critical role in normal function of the mammalian nervous system. Astrocytes regulate synaptic transmission and plasticity, protect neurons against toxic compounds, and support metabolically to ensure their optimal functioning.
Astrocytes: Current Biology - Cell Press
2021年4月12日 · Astrocytes perform core homeostatic functions in the brain. They are an integral part of the blood–brain barrier (BBB), where they not only sense and respond to peripheral insults, such as inflammation, but also take up metabolites to fuel the brain.
