Destroy senescent cells and you may have cured Alzheimer's.
Prevent cells from becoming senescent in the first place and you'll have cured human aging as we understand it.
Is that technology decades-to-centuries away? Doesn't seem like it. We've inserted hTERT into cells' genomes and permanently prevented senescence. Of course, randomly dropping genetic code into the genome tends to break shit; what's viable at the cell level is not necessarily viable on the organismal level.
So for decades we thought: what if there was a way to temporarily give cells the message to produce enough hTERT to re-lengthen their telomeres?
Maybe just a few fake instructions to make the protein that didn't come from the DNA itself. Maybe... something like...
