The interaction of the tumor necrosis factor receptor (TNFR) family member CD27 on naive CD8+ T (Tn) cells with homotrimeric CD70 on antigen-presenting cells (APCs) is necessary for T cell memory fate determination. Here, we examined CD27 signaling during Tn cell activation and differentiation. In conjunction with T cell receptor (TCR) stimulation, ligation of CD27 by a synthetic trimeric CD70 ligand triggered CD27 internalization and degradation, suggesting active regulation of this signaling axis. Internalized CD27 recruited the signaling adaptor TRAF2 and the phosphatase SHP-1, thereby modulating TCR and CD28 signals. CD27-mediated modulation of TCR signals promoted transcription factor circuits that induced memory rather than effector associated gene programs, which are induced by CD28 costimulation. CD27-costimulated chimeric antigen receptor (CAR)-engineered T cells exhibited improved tumor control compared with CD28-costimulated CAR-T cells. Thus, CD27 signaling during Tn cell activation promotes memory properties with relevance to T cell immunotherapy. [Display omitted] • CD27 is rapidly endocytosed in activated naive T cells after binding its ligand CD70 • CD27-TRAF2-SHP-1 modulates Lck phosphorylation in CD28-costimulated naive T cells • CD27 signaling promotes phenotypic and transcriptional adaptations of T cell memory • CAR-T cells generated with CD27 costimulation have superior antitumor efficacy Interaction of CD27 on naive T cells with CD70 on antigen-presenting cells is necessary for T cell memory fate determination. Jaeger-Ruckstuhl et al. engineer a trimeric CD70-ligand and assess consequences of CD27 ligation on receptor regulation, early proximal signaling, transcriptional and epigenetic states, revealing how modulation of T cell activation by CD27 affects fate commitment and efficacy of T cell immunotherapy.
