Astrocytes are star-shaped glial cells in the brain and spinal cord that perform various functions, such as regulating blood flow, nutrients, and synapses. Learn about their structure, types, energy use, development, and clinical significance in this comprehensive article.
1 maj 2023 · 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.
Astrocytes are specialized glial cells that outnumber neurons by over fivefold. They contiguously tile the entire central nervous system (CNS) and exert many essential complex functions in the healthy CNS.
12 kwi 2021 · Learn about astrocytes, the largest and most diverse glial cells in the central nervous system, and their functions in normal and pathological conditions. Find out how astrocytes originate, mature, and respond to various stimuli, and what markers can be used to identify them.
9 mar 2017 · Astrocytes are now considered as full-fledged participants in brain circuitry and processing, and display a large spectrum of functions at the cell level, such as the formation, maturation and elimination of synapses, ionic homeostasis, clearance of neurotransmitters, regulation of extracellular space volume, and modulation of synaptic activity ...
16 lut 2022 · Astrocytes regulate glutamate and ion homeostasis, cholesterol and sphingolipid metabolism and respond to environmental factors, all of which have been implicated in neurological diseases.
25 sty 2021 · Astrocytes play multifaceted and vital roles in maintaining neurophysiological function of the central nervous system by regulating homeostasis, increasing synaptic plasticity, and sustaining neuroprotective effects.
