Adenosine A2A receptor
G_A2AWhat does this word mean?
The primary molecular target of PDRN, a G protein-coupled receptor that is engaged by adenosine and starts the downstream cascade.
Expanded note
The A2A pathway has been observed to be conserved across different PDRN sources, but which downstream pathways it activates depends on the tissue type and the type of injury. That is the direct reason why the same molecule can behave differently in different parts of the body, and the direct evidence against oversimplifying topical as equivalent to injectable.
Not a generic example.
PMID 40004232 shows that DNA fragments derived from human placenta MSCs also act through the A2A receptor in a skin wound model.

PDRN is not approved by the FDA for injection or any therapeutic use. Topical and injectable PDRN are parallel facts under different regulatory pathways and must not be directly equated.
PN is not PDRN. Evidence grades are labelled on every factual element; in vitro and animal research is never described as clinical efficacy.
