    BATF may improve the anti-tumor response of CAR-T cells by deviating the phenotype and transcription profile of CAR-T cells to enhance their effector functions


    When CD8+ T cells encounter antigens and effective costimulatory signals, they will produce a strong response to eliminate pathogen-infected cells and tumor cells


    Recently, Professor Hyungseok Seo and his team have carried out research on CAR-T cells, proving that over-expressed BATF can cooperate with IRF4 to combat the development of T cell failure


    The researchers injected B16F0-hCD19 tumor cells into the previous five mice and used five age-matched C57BL/6 mice as a control group


    Frequency of CAR-T cells in spleen cells and draining lymph nodes (dLN) of C57BL/6 mice

    In view of these data, the researchers put forward a hypothesis: whether the co-expression of IRF4 and BATF will further improve the anti-tumor response of CD8+TILs


    In short, both BATF and IRF4 are induced by TCR activation.
