WebFeb 10, 2024 · Because myelin acts to increase the speed and efficiency of signals passing along axons, changes in myelination may influence important electrical signaling patterns within neural networks. In their new study the researchers discovered that losing the ability to form new myelin produced long-term changes in the activity of neurons in the mouse ... WebApr 30, 2024 · The 9w+3w/Veh mice showed a reduced g-ratio compared with the 9w mice, indicative of increased myelin sheath thickness during normal diet-induced remyelination, and 9w+3w/ERβ mice exhibited a further significant decrease in g-ratio, indicative of a further increase in myelin sheath thickness, indeed close to that of normal controls (SI ...

WebCompared with TBI alone, 6,000 m HA exposure increased SMI32 immunostaining and led to loss of MBP-positive myelin in mice, as shown by an increase in the SMI32/MBP ratio in the CC (Figure 2G, p < 0.01). These experiments strongly suggest that HA may aggravate TBI-induced necrosis of hippocampal neurons and myelin pathology. WebMyelin basic proteins are a group of seven proteins produced from a single gene mapped to chromosome 18q22–q23 by alternate splicing, and found in the central and peripheral nervous system myelin.
