We are focusing on T cell biology, CAR-T/TCR-T therapies, immune checkpoints like LAG3, and Treg function regulation. We aim to advance cancer and autoimmune immunotherapy through cutting-edge research and innovation.
🔓 New #CellPreview by Prof. Kai W. Wucherpfennig @harvard.edu highlights our work on LAG3!

Key take:
• Cbl-mediated, non-degradative poly-ubiquitination at K498 unlocks LAG3 signaling
• Marks TILs that respond to PD-1/LAG3 combo

Unlocking LAG3: Ubiquitin’s unexpected role
The inhibitory receptor LAG3 is the target of the FDA-approved mAb relatlimab, but its mechanism of signaling is not well understood. In this issue of Cell, Jiang et al. demonstrate that ubiquitinatio...

Ligand-induced ubiquitination unleashes LAG3 immune checkpoint function by hindering membrane sequestration of signaling motifs
This study uncovers the molecular mechanism of LAG3 activation upon ligand engagement and its regulation by non-degradative polyubiquitination within the tumor microenvironment. The findings highlight...
