Epigenetic locking of Foxp3 in Tregs
Stable regulatory T cells fully demethylate a conserved foxp3 region; TGF-β–induced Tregs do not.

Study at a glance
- Design
- Animal / in-vitro — Bisulphite sequencing and ChIP of foxp3/TSDR in natural vs TGF-β–induced regulatory T cells
- N
- Epigenetic comparison of Treg populations — no single primary analytic N in stored text
- Population
- Natural and induced Foxp3+ regulatory T cells (and comparator thymocytes)
- Outcome
- Demethylation of foxp3 regulatory regions predicting Treg stability
Structured fields used in claim comparison tables when every cited study has a complete layer.
What they did
Bisulphite sequencing and ChIP compared natural Tregs, thymocytes, and TGF-β–induced Foxp3+ cells.
What they found
TSDR-like element is demethylated in stable Tregs; weak demethylation predicts unstable induced Foxp3.
The limits
What it doesn't show
Mostly mouse data; human translation needs care.
