Non-canonical IL-2 signaling facilitates peripheral regulatory T cell differentiation

Amelia Meecham, Sarah Hyun Ji Kim, Mikhael Haruo Fernandes de Lima…·Mark H. Ginsberg

This study identifies MACS as a non-canonical IL-2 signaling pathway that promotes Treg differentiation and function through AP-1-dependent mechanisms.

A CD25-CCR7 complex initiates non-canonical IL-2 signaling

Sarah Hyun Ji Kim, Ho-Sup Lee, Alexandre R. Gingras…·Mark H. Ginsberg

This study identifies an IL-2 mutant that disrupts alternative signaling by blocking CD25-CCR7 complex formation while preserving canonical signaling.
