I suppose if you created a viral vector that injected an mRNA with a nuclear localization signal - what would you use to activate it? Include a steroid promoter (or other) and co-inject with cortisone? None of my prediction needs crispr though so i don’t think that’s what they’ll do.
They’ll also need to address cellular debris/degradation products as well as gene issues. I’m sure lipofuscin, anthracotic plaque, tau tangles, amyloid plaques, oxidative damage, non-enzymatic glycosylation, etc will all ultimately need to be addressed.
I hope they do skin first, I’m tired of looking like a wrinkle.
