DOI as a 5-HT2A research tool, why does it get ignored in longevity talk?

Saw a paper pop up recently using DOI to map 5-HT2A receptor distribution in aged mouse tissue, and it got me thinking. Most longevity and biohacking chatter skips right over the serotonergic side, but 5-HT2A signaling ties into neuroplasticity, sleep architecture, and probably some of the mood/cognition stuff people chase with other compounds.

The DOI page here on ResearchSafe calls it the standard pharmacology tool for this receptor, and the half-life is long enough that the data must be pretty clean compared to shorter-acting agonists. What caught my eye is the vasoconstriction and BP angle. If 5-HT2A is something we actually care about as we age, the cardiovascular hit is a real caveat and not something to handwave.

I am curious whether anyone here thinks 5-HT2A is a meaningful target for cognitive aging, or if it is mostly a dead end outside of psychedelic therapy research. And for those who follow this space, do you see longevity researchers picking it up more, or staying away?
