Tapping into the brain’s star power 2018-10-30T04:00:00Z Another type of glial cell, the astrocyte, provides motor neurons with nutrients, ion buffering and recycling of the neurotransmitter glutamate. Decoding ALS: from genes to mechanism : Nature : Nature Research 2016-11-08T05:00:00Z The thickness of the myelin sheath is not fixed; instead it reflects a dynamic balance between the addition of layers next to the axon and removal of the outer layer under control of the astrocyte. The Brain Learns in Unexpected Ways 2020-03-12T04:00:00Z Neurons "call" for more glucose via another cell called an astrocyte. Alzheimer's-Linked Brain Plaques May Also Slow Blood Flow 2015-11-24T05:00:00Z Here we show that astrocyte morphogenesis in the mouse cortex depends on direct contact with neuronal processes and occurs in parallel with the growth and activity of synaptic circuits. Astrocytic neuroligins control astrocyte morphogenesis and synaptogenesis 2017-11-07T05:00:00Z But there are caveats to this ‘MD astrocyte’ method — named after its developers, Ken McCarthy at the University of North Carolina School of Medicine at Chapel Hill, and Jean de Vellis at UCLA. Tapping into the brain’s star power 2018-10-30T04:00:00Z “But what comes first — the neuronal defect or the astrocyte defect — is the issue.” Neurobiology: Unrestrained excitement : Nature : Nature Publishing Group 2014-07-08T04:00:00Z Surrounding the node of Ranvier is a glial cell called an astrocyte. The Brain Learns in Unexpected Ways 2020-03-12T04:00:00Z We are only beginning to learn about the diversity, connectivity and function of astrocyte networks. Neuroscience: Map the other brain 2013-09-05T20:20:29.767Z However, the molecular means by which the astrocyte initiates and maintains the required morphology to participate in synaptic regulation are not well known. Astrocytic neuroligins control astrocyte morphogenesis and synaptogenesis 2017-11-07T05:00:00Z A dye-stained astrocyte in the rat hippocampus takes on a ‘snowflake’-like appearance.Credit: Tapping into the brain’s star power 2018-10-30T04:00:00Z Even so, these latest astrocyte findings spark new questions: What parts do lesser-known types of glia – oligodendrocytes, microglia and so on – have to play in our brains’ ongoing drama? A Secret Society of Cells Runs Your Brain 2013-06-24T22:45:05.087Z We found that the enzyme’s snipping of these threads that stitch myelin to the axon can be controlled by the perinodal astrocyte’s release of an inhibitor of thrombin.
