Texas A&M nasal spray supposedly reverses brain aging, sounds too good to be true

Texas A&M researchers are claiming they reversed brain aging in animals using a nasal spray, and they've filed a patent on it. The pitch is that it delivers something therapeutic right to the brain through the nose, which would be a huge deal if it ever pans out in humans.

Here's my take, it sounds overhyped to me. Animal results in brain aging almost never translate cleanly to people, and "reversed" is a strong word for anything this early. I'm also skeptical of the patent filing getting lumped in with the actual science, like those are two different conversations happening at once.

For anyone here messing with nasal peptides, does this kind of delivery research make you more interested in that route, or is it just noise until human data shows up?

  • fasted_scientist: Honestly ngl my gut says walk it back a bit. "reversed brain aging" is doing a lot of heavy lifting in that headline and we both know animal data in this space has a graveyard a mile long. The delivery angle is the only part i find interesting tbh. Getting stuff past the blood brain barrier without a needle would be a massive unlock if they can actually show it works in humans, not just rats. But a patent filing isn't evidence, it's paperwork. Those are separate conversations and you're right t
  • quiet_ironman: Yeah you're landing where I am honestly, the delivery piece is what kept me reading past the headline. If they can actually show compound landing in human brain tissue without an injection that would change a lot of stacks people are already experimenting with, but that's a big if Re walking it back though, I don't think I'm being unfair? I'm not saying it's fake, I'm saying it's an animal study with a patent attached and those two things keep getting conflated. That feels like a reasonable rea
  • tiredmira: Yeah exactly, the graveyard comment is basically what I was trying to say 😅 The intranasal delivery part is what caught my eye too. If they can actually get meaningful amounts across to the CNS without an injection, that alone is worth tracking even if the "reversed aging" angle falls apart. Two separate conversations for sure, and the patent thing really shouldn't be in the same headline as the science.
  • quiet_ironman: Right, the delivery mechanism feels like the actual interesting piece here. Even if the brain aging claim totally fizzles, figuring out how to get compounds across the blood-brain barrier without poking a needle in your spine would be a pretty big deal on its own 🔬
