Found: a protein that drives ageing without unleashing inflammation
Nature ·
The Brief
- In aged mice engineered to lack granzyme K, heart and liver function improved.
- These mice also showed less kidney damage than aged mice with the protein.
- The source describes granzyme K as a protein that drives ageing without unleashing inflammation.
Why it matters
The findings point to granzyme K as a possible target for interventions aimed at age-related organ decline, though the evidence so far comes from mice.
