Mechanobiology of the immune synapse: signal integration via actin dynamics
ABSTRACT Mechanical force is essential for T cell activation. It activates TCR signaling, and allows the T cell to sample the quality of TCR-pMHC interactions. This greatly expands the dynamic range of TCR responses and permits antigen discrimination during thymic selection, T cell priming, and effector responses. Our understanding of how force influences TCR-pMHC interactions has advanced significantly, thanks to biophysical studies at the single molecule level. However, there are large gaps in knowledge at the cell biological level. This project seeks to identify the biochemical and mechanical circuits within the TCR signal transduction network that permit the rapid translation of small…
