CD8HTM and CD28HTM CAR-T products lack exhaustion and possess memory phenotypes. (a) effector, effector memory, central memory, and naïve/stem cell memory-like phenotypes among matched CD8HTM and CD28HTM CAR-T cells produced from n = 3 donors. Representative flow cytometry plots are shown. (b) prevalence of 0 to 4 exhaustion markers expressed among matched CD8HTM and CD28HTM CAR-T cells produced from 3 donors. SPICE plots demonstrating the average number and type of exhaustion marker expression. CD8HTM and CD28HTM memory (a) and exhaustion (b) phenotypes were not statistically different. Statistical analyses used two-way ANOVA adjusted for multiple comparisons. Error bars reflect the standard error of the mean (SEM).
