Differential trafficking of ligands trogocytosed via CD28 versus CTLA4 promotes collective cellular control of co-stimulation
Abstract
A number of costimulatory signals are critical to the activation and regulation of T cells, but how the availability or self-regulation of these occurs was previously unclear. Here the authors show a difference in the fate of ligands trogocytosed by CD28 or CTLA4 and link this to cellular control of costimulation.
