Brain cells created from patients’ skin cells
(Medical Xpress) — Cambridge scientists have, for the first time, created cerebral cortex cells those that make up the brains grey matter from a small sample of human skin. The researchers findings, which were funded by Alzheimers Research UK and the Wellcome Trust, were published today in Nature Neuroscience.
Why two new studies represent important breakthrough in Alzheimer’s disease research
Two different research groups have independently made the same important discoveries on how Alzheimer’s disease spreads in the brain. The groups’ findings have the potential to give us a much more sophisticated understanding of what goes wrong in Alzheimer’s disease and, more importantly, what can be done to prevent or repair damage in the brain.
New procedure repairs severed nerves in minutes, restoring limb use in days or weeks
American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research.
Untangling the mysteries of Alzheimer’s
One of the most distinctive signs of the development of Alzheimer’s disease is a change in the behavior of a protein that neuroscientists call tau. In normal brains, tau is present in individual units essential to neuron health. In the cells of Alzheimer’s brains, by contrast, tau proteins aggregate into twisted structures known as “neurofibrillary tangles.” These tangles are considered a hallmark of the disease, but their precise role in Alzheimer’s pathology has long been a point of contention among researchers.
