The paper identifies CD3ε as a primary trigger subunit in TCR activation through phase separation with Lck, leading to the design of TRIG molecules that activate T and NK cells via endogenous receptor signaling.

This study shows that PD-1 ligand interactions are force-dependent and soluble PD-L1 can block PD-1, suggesting new approaches for cancer immunotherapy.

This study shows CD28 co-stimulation forms signaling condensates with Lck, which PD-1 modulates by binding and disrupting these structures, leading to engineered CAR T cells with improved antitumor activity.
