| Introduction | CD28 is a transmembrane glycoprotein expressed by T cells as well as some other hematopoietic cells. T cell activation requires T cell receptor (TCR) recognition of antigen presented in the context of MHC molecules. CD28 acts as a T cell costimulatory receptor, and interaction of CD28 with its ligands CD80 or CD86 provides the second signal required for naïve T cell activation. Activation of naïve T cells in the absence of CD28 stimulation can result in a state of T cell anergy, or unresponsiveness. CD28 signals through cytoplasmic phospho-tyrosine motifs that bind several SH2 or SH3 domain-containing proteins involved in T cell activation. Recently, CD28 was demonstrated to be a preferred target of PD-1-mediated dephosphorylation. Consistently, CD28 expression was required for T cell proliferation following PD-1 blockade and CD28 stimulation was required for effective anti-PD-1 cancer immunotherapy in mice. Several CD28 isoforms are produced by alternative splicing. |
