I call them packets of emails.
They're tiny segments of RNA called micro RNAs.
They travel through the body and tell other cells what's happening and what to do.
In studies on parabiosis, where we connect the circulation of an old animal to a young one, the old animal starts to rejuvenate.
A big part of that effect comes down to these micro RNAs being shared between the two systems.
Here's the thing: our DNA is programmed to age.
Over time, the signals it sends change.
The micro RNAs it expresses shift.
But when you introduce micro RNAs from a younger system, you start to see rejuvenating effects.
That's what exosome research is pointing toward.
The ability to sequence those signals, package them, and deliver them into the human body.
We're still in early days.
But the direction is clear.
What questions do you have about exosomes or cellular signaling?
