Astrocytes (green) in the context of neurons (red) in a mouse cortex cell culture 23-week-old fetal brain culture human astrocyte Astrocytes (red-yellow) among neurons (green) in the living cerebral cortex. Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells.
Astrogliosis (also known as astrocytosis or referred to as reactive astrogliosis) is an abnormal increase in the number of astrocytes due to the destruction of nearby neurons from central nervous system (CNS) trauma, infection, ischemia, stroke, autoimmune responses or neurodegenerative disease.
These cells do not simply carry out functions of structural support, but can also take part in cell-to-cell communication with neurons, microglia, and other astrocytes by receiving inputs, organizing information, and sending out chemical signals. [5] The Ca 2+ signal from the astrocyte may also participate in controlling blood flow in the brain ...
Spanish Fort is located at the end of Farm to Market Road 103, one mile south of the Red River, 26 mi (42 km) northeast of Montague, 17 mi (27 km) north of Nocona, and 37 mi (60 km) northeast of Bowie in north-central Montague County.
SGCs are present in the PNS in fewer numbers than other more well-known types of glial cells, like astrocytes, but have been determined to affect nociception because of some of their physiological and pharmacological properties. [21] In fact, just like astrocytes, SGCs have the ability to sense and regulate neighboring neuronal activity. [30]
Glial fibrillary acidic protein (GFAP) is a protein that is encoded by the GFAP gene in humans. [5] It is a type III intermediate filament (IF) protein that is expressed by numerous cell types of the central nervous system (CNS), including astrocytes [6] and ependymal cells during development. [7]
Astrocytes have large numbers of potassium ion channels facilitating the removal of potassium ions from the extracellular fluid. They are taken up at one region of the astrocyte and then distributed throughout the cytoplasm of the cell, and further to its neighbors via gap junctions.
Spanish Fort is a city in Baldwin County, Alabama, United States, located on the eastern shore of Mobile Bay. The 2020 census lists the population of the city as 10,049. [ 2 ] It is a suburb of Mobile and is part of the Daphne-Fairhope-Foley metropolitan area .
