<div dir="ltr">"When it comes to Alzheimer’s versus science, science is on the losing side.
<p>Alzheimer’s is cruel in the most insidious way. The disorder creeps
up in some aging brains, gradually eating away at their ability to think
and reason, whittling down their grasp on memories and reality. As the
world’s population ages, Alzheimer’s is rearing its ugly head at a
shocking rate. And despite decades of research, we have no treatment—not
to mention a cure.</p>
<p>Too much of a downer? The National Institutes of Health (NIH) agrees. In <a href="https://www.ninds.nih.gov/News-Events/News-and-Press-Releases/Press-Releases/NIH-scientists-try-new-twist-using-personalized-stem-cells">one of the most ambitious projects</a> in biology, the NIH is corralling Alzheimer’s and stem cell researchers to come together in <a href="https://www.sciencedirect.com/science/article/abs/pii/S0896627321001926">the largest genome editing project</a> ever conceived.</p>
<p>The idea is simple: decades of research have found certain genes that
seem to increase the chance of Alzheimer’s and other dementias. The
numbers range over hundreds. Figuring out how each connects or
influences another—if at all—takes years of research in individual labs.
What if scientists unite, tap into a shared resource, and collectively
solve the case of why Alzheimer’s occurs in the first place?</p>
<p>The initiative’s secret weapon is induced pluripotent stem cells, or
iPSCs. Similar to most stem cells, they have the ability to transform
into anything—a cellular Genie, if you will. iPSCs are reborn from
regular adult cells, such as skin cells. When transformed into a brain
cell, however, they carry the original genes of their donor, meaning
that they harbor the original person’s genetic legacy—for example, his
or her chance of developing Alzheimer’s in the first place. What if we
introduce Alzheimer’s-related genes into these reborn stem cells, and
watch how they behave?</p>
<p>By studying these iPSCs, we might be able to follow clues that lead to the genetic causes of <a href="https://singularityhub.com/2019/03/05/the-gene-therapy-trial-aiming-to-fend-off-alzheimers/">Alzheimer’s</a> and other dementias—paving the road for gene therapies to nip them in the bud."</p><p><a href="https://singularityhub.com/2021/04/13/a-massive-new-gene-editing-project-is-out-to-crush-alzheimers/">https://singularityhub.com/2021/04/13/a-massive-new-gene-editing-project-is-out-to-crush-alzheimers/</a></p>
