In vitro functional validation of anti-CD19 chimeric antigen receptor T cells expressing lysine-specific demethylase 1 short hairpin RNA for the treatment of diffuse large B cell l... by Zhi Guo, Zhi Guo, Mingxin He, Ning Liu, Yiqing Yang, Rui Sun, Jianxun Wang, Qiang Wang

“…Epigenetic modifications can regulate T cell activation, maturation and depletion; they can be applied to reduce T cell depletion, improve infiltration, and promote memory phenotype formation to reduce relapse after CAR-T cell therapy.PurposeWe propose to develop and validate in vitro the function of novel CAR-T cells for the treatment of DLBCL, which simultaneously express an anti-CD19 CAR with lysine-specific demethylase 1 (LSD1) short hairpin (sh)RNA to prevent depletion and prolong the survival of CAR-T cells.MethodsWe designed an shRNA sequence targeting LSD1 mRNA, and created a vector with the following elements: the U6 promoter driving expression of the LSD1 shRNA sequence, the EF1a promoter driving a second-generation anti-CD19 CAR sequence encoding an anti-CD19 single-chain variable fragment (FMC63), the CD8 hinge and transmembrane structural domains, the CD28 co-stimulatory structural domain, and the CD3ζ-activating structural domain. …”
