Ligand stabilization enables physiological GITR signaling and antitumor immunity

Tesfahun Dessale Admasu, Keerthi Caroline Sadanala, Dnyaneshwar Kalyane…·John Yu

This study shows that stabilizing the GITRL ligand enhances antitumor immunity by enabling physiological signaling between APCs and T cells, unlike receptor-targeted antibodies.

Butyrophilin 2A2 promotes T cell immunoregulation by enhancing CD45 phosphatase activity within the immune synapse

Shafat Ali, Anders Hayden Berg, Michifumi Yamashita…·S. Ananth Karumanchi

This study identifies BTN2A2 as a CD45RO ligand that enhances CD45 phosphatase activity, promoting Treg expansion and reducing Th17 cells, thereby ameliorating autoimmunity in mice and humans.
