Figure 5. CART123 establish long-term immunological memory in mice with HL.
A. Experiment schema: mice previously treated with CART123 and experiencing a long-term remission were rechallenged at day 250 with HL cells (HDLM-2). As a control a tumor-naïve group of mice were also injected with the same HL cells. B. HL cells only engrafted and grew in tumor-naïve mice while long-term surviving mice (post-CART123) were able to control disease growth. C. A re-expansion of CART123 cells was observed in mice previously treated with CART123. D. An improved overall survival was observed in mice with previous exposure to CART123.
