WebJul 24, 2024 · Oligodendrocytes produce and repair myelin, which is critical for the integrity and function of the central nervous system (CNS). Oligodendrocyte and oligodendrocyte progenitor cell (OPC) biology is modulated in vitro by mechanical cues within the magnitudes observed in vivo. In some cases, these cues are sufficient to accelerate or … Oligodendrocytes (from Greek 'cells with a few branches'), or oligodendroglia, are a type of neuroglia whose main functions are to provide support and insulation to axons in the central nervous system of jawed vertebrates, equivalent to the function performed by Schwann cells in the peripheral … See more Oligodendrocytes are a type of glial cell.

WebThe authors propose that the linear EBNA1 peptide cross-reacts with a phosphorylated, intracellular, C-terminal epitope of the mammalian GlialCAM protein (aa370-389), which is expressed by astrocytes and by the oligodendrocyte-myelin unit. Importantly, rodent vaccination with EBNA1 aa386-405 alone was insufficient to trigger rodent EAE. WebMultiple sclerosis is caused by a loss of the myelin sheath around neurons. Major glial cells in the brain include oligodendrocytes (blue), astrocytes (green) and microglia (maroon). Neurons are shown in yellow, with the …
WebJan 18, 2024 · The Blood-Brain Barrier (BBB) is a selective wall of cells and surrounding blood vessels that protects the brain from foreign invaders by preventing their entry. Some small invaders can pass through, but the immune cells that fight them in the rest of the body cannot. Instead, microglia act as the immune cells of the brain.
