Implication

Randomized trial demonstrates immune tolerance induction in mice using an IL-2-TGF-β agonist, suggesting potential for treating immune-related diseases.

Key Points

The aim is to investigate a novel IL-2-TGF-β surrogate for inducing peripheral regulatory T cells (pTregs) to achieve immune tolerance.
Designed an IL-2-TGF-β surrogate co-agonist using a single-chain fusion protein.
Examined its effects in vivo on immunized mice (OVA and MOG35-55).
Analyzed signaling pathways activated in IL-2 receptor-expressing T cells.
The surrogate agonist induced stable pTregs in peripheral lymphoid organs of immunized mice.
Induced pTregs demonstrated high Rorγt expression and actively expanded for effective inflammation suppression.
Mitigated immune activation in models of allergic inflammation and autoimmune neuroinflammation.
