CD45-mediated control of TCR tuning in naïve and memory CD8+ T cells
Abstract
Naïve T cells establish self-tolerance via negative selection of cells with strong reactivity for self-peptide/MHC complexes, but undergo T-cell receptor (TCR) desensitisation when leaving the thymus. Here, Choet al.show that TCR desensitisation correlates with cell-surface density of the phosphatase CD45.
