Smarter™ 7 × 19 CAR Construction Service

Online Inquiry

CAR engineered T cell therapy has developed rapidly in recent years. Use of chimeric antigen receptors (CARs) as the basis of targeted adoptive T cell therapies has enabled dramatic efficacy against multiple hematopoietic malignancies, but potency against solid tumors has lagged, potentially due to insufficient CAR-T cell expansion and persistence. To improve CAR-T cell efficacy, Creative Biolabs is proud to present a new generation CAR-T cells to express interleukin (IL)-7 and CCL19 (7 × 19 CAR-T cells), as these factors are essential for the maintenance of T-cell zones in lymphoid organs, with superior anti-tumor activity compared to conventional CAR-T cells.

Introduction of 7 × 19 CAR

Studies have shown that IL-7 and CCL19 are produced by T-region fibroblast reticulocytes, which are essential for the formation and maintenance of T-cell regions in lymphoid organs, in which T cells and DCs can be recruited from the periphery. Therefore, to improve CAR-T cell efficacy, we develop potent functional elements based on IL-7 and CCL19 signaling domains, which can mimic the function of T-zone reticular cells, and recruit T cells and DCs to tumor tissues to improve the therapeutic effect of CAR-T cells against solid tumors.

To obtain 7 × 19 CAR constructs, we generate a tandem construct encoding the CAR, IL-7, and CCL19 with two 2A peptide sequence between the genes. This novel, regulatable 7 × 19 system may promote the infiltration of dendritic cells (DC) and T cells into tumor tissues.
