Regrowing Neurons, The Technology To Cure Alzheimer

German researchers have found a way to regenerate brain cells after a traumatic brain injury. They tested this technology on mice and until now they got amazing results. This idea could be used to help people which suffer from Alzheimer disease - the idea is to replace neurons just like they did with the mice, but for now the methods are “not so perfect”.

A report in the Proceedings of the National Academies of Science says : “Magdalena Götz and colleagues found that cells called astrocytes expand and multiply after brain injury. The authors induced brain injury in mice, then observed as quiescent astrocytes activated themselves and became reactive, causing reactive gliosis, which is the universal cellular reaction to brain injury. The researchers found that the reactive astrocytes remained astrocytes in the cerebral cortex, whereas in a cell culture they could be coaxed to switch to different brain cell types, including neurons. These results identify astrocytes as a source of stem cells in the injury site and show that other types of brain cells do not have this potential. The authors conclude that the cells provide a promising cell type to initiate repair in humans after brain injury.”
