Hypothesis
Can TGF-β1 induce signaling in a non-activated form while still residing in a complex?
Conclusion
The study reveals that TGF-β1 can signal without being released from its latent form, challenging previous understandings of its activation.
Supporting Evidence
- TGF-β1 can signal without being released from its latent form.
- Dynamic allostery explains the mechanism of TGF-β3 latency and activation.
- Targeting TGF-β activation through CER offers opportunities for directional context-dependent TGF-β activation.
Takeaway
This study shows that TGF-β1 can work even when it's not fully activated, which could change how we think about treating diseases like cancer.
Methodology
The authors used advanced methods and genetic mouse models to study TGF-β signaling.
Limitations
The study does not clarify how LTBP affects intrinsic flexibility or CER, which requires further investigation.
