CD43 is a checkpoint against KLRG-1+CD49dhi effector CD8+ T cell formation.
Upon recognition of alloantigen, T cells rely on an array of costimulatory and coinhibitory receptors to shape their activation and function. The surface receptor CD43 has been reported to provide myriad functions on T cell related to adhesion, trafficking, and intracellular signaling. We investigated the role of CD43...
