While Muller glia division is responsible for the regeneration of the retina in all cases of retinal damage, the case of photoreceptor loss due to light damage is particularly well characterized. In response to photoreceptor ablation, Muller glia dedifferentiate and undergo a single asymmetric division to produce a neural progenitor cell and a ...
In the central nervous system (CNS), glia suppress repair. Glial cells known as astrocytes enlarge and proliferate to form a scar and produce inhibitory molecules that inhibit regrowth of a damaged or severed axon. In the peripheral nervous system (PNS), glial cells known as Schwann cells (or also as neuri-lemmocytes) promote repair. After ...
GliA is a transporter involved in the secretion of gliotoxin, and it has been found that depletion of the GliA protein would result in cell death in A. fumigatus and significantly increase A. fumigatus sensitivity to gliotoxin. [18]
Neuroregeneration is the regrowth or repair of nervous tissues, cells or cell products. Neuroregenerative mechanisms may include generation of new neurons , glia , axons , myelin , or synapses . Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms involved ...
Olfactory ensheathing cells (OECs), also known as olfactory ensheathing glia or olfactory ensheathing glial cells, are a type of macroglia (radial glia) found in the nervous system. They are also known as olfactory Schwann cells , because they ensheath the non- myelinated axons of olfactory neurons in a similar way to which Schwann cells ...
Gliogenesis results in the formation of non-neuronal glia populations from neuronal cells. In this capacity, glial cells provide multiple functions to both the central nervous system (CNS) and the peripheral nervous system (PNS). Subsequent differentiation of glial cell populations results in function-specialized glial lineages.
The report, which cites witness testimony, financial records, and text message exchanges, found that Gaetz violated Florida law and House ethics rules while he was a member of Congress, and ...
The brain parenchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and glial cells. [7] It is also known to contain collagen proteins. [8] Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.
