Accumulation of dynamic catch bonds between TCR and agonist peptide-MHC triggers T cell signaling

B Liu, W Chen, BD Evavold, C Zhu - Cell, 2014 - cell.com
TCR-pMHC interactions initiate adaptive immune responses, but the mechanism of how
such interactions under force induce T cell signaling is unclear. We show that force prolongs …

The magnitude of LFA-1/ICAM-1 forces fine-tune TCR-triggered T cell activation

VPY Ma, Y Hu, AV Kellner, JM Brockman… - Science …, 2022 - science.org
