Abstract

Developing T cells commit to either CD4/helper or CD8/cytotoxic lineage in the thymus, but how CD4 and CD8 coreceptors and TCR signaling dictate this selection process is still unclear. Here the authors use single cell RNA sequencing of mouse thymocytes to show that, in selection intermediates, TCR signaling strength informs coreceptor expression timing.
