Wake up and die: Human brain neurons re-entering the cell cycle age quickly shift to senescence - EurekAlert


<p>Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer&rsquo;s disease, according to a new study published April 9<sup>th</sup> in the open-access journal <em>PLOS Biology</em> by Kim Hai-Man Chow and colleagues at the Chinese University of Hong Kong. The phenomenon may provide an opportunity to learn more about the neurodegeneration process, and the technique used to make this discovery is readily applicable to other inquiries about unique populations of cells in the brain.</p>
