Instead of being a central cell with membrane-tipped arms, Schwann cells form spirals directly around the axon. The nodes of Ranvier sit between them, just as they do with oligodendrocytes, and assist in nerve transmission in the same way. Schwann cells are also part of the PNS's immune sy...
This symposium will highlight some the functions associated with the three glial cell-types of the retina. Glial cells actively interact with each other as well as with neurons and the vasculature and participate in the generation of the electroretinogram and spreading depression. Particularly ...
The astrocytes are the next most abundant type of glial cell. They perform a dizzying array of functions, all of which follow the general trend of ‘taking care of the brain’. They clean up the brain’s toxic trash, secrete the right chemicals that make the brain comfortable for cells, ...
A2ARs in glial cells may exert complex actions on neuronal cell death (both, potentially deleterious as well as neuroprotective) and possibly other functions such as modulation of synaptic transmission. In astrocytes, activation of A2ARs by extracellular adenosine increases astrocyte proliferation and act...
[13,14,15]. On the other hand, the diversity of functions and glial cell types increases with the complexity of the nervous system. The increasing number of glia (from 10% of total brain volume in model invertebrates to over 50% in mammals), glia-to-neuron ratio, and glial cell ...
Organization and Function of the Blood–Brain Barrier in Drosophila The function of a complex nervous system depends on an intricate interplay between neuronal and glial cell types. One of the many functions of glial cells ... T Stork,D Engelen,A Krudewig,... - 《Journal of Neuroscience》 ...
Muller cells have a range of functions all of which are vital to the health of the retinal neurons. Muller cells function in a symbiotic relationship with the neurons (for an excellent review see Reichenbach and Robinson, 1995). Thus Muller cell functions include: Supplying endproducts of anaero...
Most neurons share the same cellular components. But neurons are also highly specialized—different types of neurons have different sizes and shapes that relate to their functional roles. Parts of a Neuron Like other cells, each neuron has a cell body (or soma) that contains a nucleus, smooth...
These receptors mediate both short-term events such as neurotransmission and secretion and long- term events such as cell proliferation, differentiation and death, important in development and regeneration. The emphasis in this presentation will be to discuss the long-term purinergic signalling that ...
Physiological Functions of Glial Cell Hemichanneis The brain performs exceptionally complex and dynamic tasks that depend on the coordinated interaction of neurons, glial cells, endothelial cells, pericytes... JA Orellana - 《Advances in Experimental Medicine & Biology》 被引量: 0发表: 2016年 [...
