Tissue Regulatory T Cells FOXP3+ regulatory T cells (Tregs) have well-defined roles in limiting systemic immune responses against diverse stimuli. However, the observation that a subset of Tregs also enter nonlymphoid tissues,...

Our latest review is out, a comprehensive synthesis of #tissue #Tregs. It has been a decade since @annualreviews.bsky.social #immunology last reviewed #TissueTregs, and there have been enormous advances and conceptual leaps forward in the field

Wonderful to see the seminal discoveries of Shimon Sakaguchi, Mary E. Brunkow & Fred Ramsdell recognised with the Nobel Prize. From Sakaguchi’s discovery of Treg cells to the identification of Foxp3, their research opened a new chapter in immunology, viewed from the prism of dominant tolerance.

A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine
