So we took blood from young people or old people and injected into mouse brain. we could show that young blood um could in fact mimic the effects of young mouse blood.

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Young blood has been shown to enhance cognitive function, stem cell function, and tissue repair, as well as increase the lifespan of rodents.
The Conboy lab reports the ability of young blood transfusions to reverse 🐭 aging is mimicked by a simple replacement of blood with a neutral age fluid [saline + 5% albumin] with benefits in muscle, liver, and new brain cell formation (image)💪#aging https://t.co/tK6CeeiHCd https://t.co/rdiEcs8kGO
But this new study suggests that young blood is not needed for rejuvenation. Old blood contains age-accelerating factors so dilution of it was enough to reverse aging.
Diluting blood in old mice by replacing half of the plasma with a saline and albumin mixture was able to reverse aging in the brain, liver, and muscle.
Young blood transplanted into old mice reverses brain & muscle aging.
when they transplant, for example, blood from young mice into old mice, something happens that are able to regenerate liver heart...
they were able to take this plasma and, you know, basically, it was just the saline and albumin...they took old mice and, like, it was essentially diluting out their old plasma and it rejuvenated these mice. Whereas they did it with the young mice, there's really no effect. Yeah. So, it really indicates, like, there is, as you mentioned, there's something accumulating, at least in the bloodstream, with age that may, in some way, be accelerating the aging process.
