IL-13 Induces a Tuft Cell-Intrinsic CD45 Checkpoint to Limit Intestinal Type 2 Immunity

Carmel Sochen, Sacha Lebon, Aviya Habshush Menachem, Avital Sarusi-Portuguez, V. V. Holiar, Vladislav Rudenko, Barak Toval, Jingjing Liu, Yishai Levin, Ella Vaaknin, Noa Rosenthal, Noa Tiferet, Irit Orr, Shifra Ben‐Dor, Rebecca Haffner‐Krausz, , Moshe Biton

This study identifies CD45 as a tuft cell-intrinsic checkpoint that limits intestinal type 2 immunity through an IL-13-induced negative feedback mechanism.

Epithelial MHC II antigen presentation dynamically informs intestinal homeostasis and injury

V. V. Holiar, Vladislav Rudenko, Chen Weller, Mariia Naumova, Sacha Lebon, Marco Canella, Petro Busko, Avital Sarusi-Portuguez, Tali Shalit, Aviya Habshush Menachem, Idan Adir, Zachary Petrover, Polina Greenberg, Corine Katina, Polina Gradchenko, , Moshe Biton

This study shows that epithelial MHC II antigen presentation encodes tissue state and injury signals, maintaining homeostasis and promoting tolerance, while shifting toward damage-associated antigens during inflammation.
