Anti-CD22 KIR CAR (XW-90) Vector (XS-1122-YF90)

Online Inquiry  Datasheet

All products and services are For Research Use Only and CANNOT be used in the treatment or diagnosis of disease.

The vector of anti-CD22 KIR chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target Human CD22. The T cells are genetically modified through transduction with a lentiviral vector expressing scFv (XW-90) of anti-CD22 antibody linked to KIR2DS2 TM & ICD and DAP12. The vector product was designed for the discovery and development of cellular therapy against Acute lymphoblastic leukemia (ALL). This KIR signaling is designed to prolong KIR-CAR T cells' efficacy period by coupling the receptor chains during activation and decoupling them during rest, avoiding T cell exhaustion even in challenging solid-tumor environments.

  • Discription of Signaling Cassetes
  • The dual binding and signal chains are designed to come together to form a single receptor complex when bound to a tumor target. Dual chain signaling provides prolonged T cell activation even in challenging solid-tumor environments. KIR CAR combines the power of NK cell KIR receptors with the long-term durability of T cells, resulting in a long-lasting and powerful anti-cancer efficacy. KIR CAR-T cells maintained activation and potent cytotoxic activities in solid tumors compared with the CD28 and 4-1BB co-stimulated CD3-ζ -based traditional CAR T cells. The DAP12 signal functions as both activation and co-stimulation for T cells, circumventing the CD3-ζ pathway to allow prolonged KIR-CAR function.
