myelin. Myelin acts like the protective and insulating plastic casing around the electrical wires of the brain - called axons. Myelin is essential for superfast communication between nerve cells that lie behind the supercomputer power of the human brain. The loss of myelin results in cognitive decline and is central to several neurodegenerative diseases, such as Multiple Sclerosis and Alzheimer’s disease. This new study found that the cells that drive myelin repair become less efficient as we age and identified a key gene that is most affected by ageing, which reduces the cells ability to replace lost myelin.
Everyone is familiar with the brain’s grey matter, but very few know about the white matter, which comprises of the insulated electrical wires that connect all the different parts of our brains. ....
By JULIAN SHEA in London | China Daily Global | Updated: 2021-03-15 04:55 Share CLOSE A new study led by the University of Portsmouth in England has identified a significant feature in the deterioration of the insulation of the wiring of the human brain, which could play a major role in the prevalence of neurodegenerative conditions such as Multiple Sclerosis (MS) and Alzheimer s, which is a major medical challenge facing the ageing society of China and other countries. The substance in question is called myelin and acts as a protective casing for neurological electrical connections called axions, enabling the high-speed sending of messages between nerve cells. ....

Myelin Loss Plays Key Role in Age-Related Brain Deterioration March 11, 2021 Image depicts myelin (Cyan) and oligodendrocyte progenitor cells (OPCs) in the grey and white matter of the brain. Myelin is produced by oligodendrocytes, which are in turn produced by OPCs. The nuclei of all the cells in the brain are shown in blue. [Andrea Rivera, PhD] An international research team led by scientists at the University of Portsmouth says it has identified that one of the major factors of age-related brain deterioration is the loss of myelin. They published their study “Functional genomic analyses highlight a shift in Aging Cell. ....
