Bird Flu a “Single Mutation” Away from Humans Stuck Stem Cells Culprit for Gray Hair This Mouse Has Genes Older Than All Animal Life Memory Isn’t Exclusive To the Brain Scientists May Have Found Why Some 'Hear Voices' Scientists Hit the “Pause Button” on Human Life...
We see that they like to drill into astrocytes around the blood-brain barrier. They also like to drill into axons. Axons are the protruding parts of the brain that carry out information transmission and are covered with lipid rich myelin sheaths. In addition, in mice (not humans), they als...
Here are some of the types of tumors and a little about each of them: Astrocytomas These grow in star-shaped cells called astrocytes in thebrainand spinal cord. They belong to a group of tumors called gliomas. All gliomas grow from “glial cells,” which support and protect your nerve fib...
Finally, we examine how changes in curvature can influence transcriptional regulation through a reorganization of cytoskeletal forces acting on the nucleus, thereby facilitating the development of specific human diseases. Key points Cells interact with the curved surfaces of many organs and, at a lower...
To that end, we extensively describe a variety of studies involving topics such as neurodevelopment, aging, stress, memory and homeostatic plasticity to highlight how the weakening and disconnection of synapses organically permeate the brain in so many ways as a good practice of its intrinsic ...
(e, insert); f: dystrophic axons at the lesion edge show accumulation of amyloid precursor protein (APP) as a sign of disturbed axonal transport; g, h: Profound protoplasmic astrocytic gliosis is seen in sections stained for glial fibrillary acidic protein (GFAP); some of the astrocytes ...

The spinal cord is long thing tube made of bundles of nerves that travel to and from the brain to the rest of the body. The spinal cord can be divided in to a dorsal part (toward the back of the body) where the sensory pathways are located and a ventral part (towards the front of...
ASTROCYTES Star-shaped cells that support the tissue of the central nervous system. IMMUNOGLOBULIN-α CONSTANT REGION Region of an antibody molecule that is constant within ? and defines ? each of the basic classes of immunoglobulin. ANTIBODY CLASS SWITCHING Process by which the region of an immu...
They also found that when exposed to stress hormones called glucocorticoids, the astrocytes remove too many connections (synapses) between brain cells. Synapses link sensory organs in the peripheral nervous system to the brain, allowing signals related to sensations like pai...
