Anti-CD70 KIR CAR (XW-208) Vector (XS-1122-YF208)


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

The vector of anti-CD70 KIR chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target Human CD70. The T cells are genetically modified through transduction with a lentiviral vector expressing scFv (XW-208) of anti-CD70 antibody linked to KIR2DS2 TM & ICD and DAP12. The vector product was designed for the discovery and development of cellular therapy against Colorectal cancer. 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.

  • Introduction
  • The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for TNFRSF27/CD27. It is a surface antigen on activated, but not on resting, T and B lymphocytes. It induces proliferation of costimulated T cells, enhances the generation of cytolytic T cells, and contributes to T cell activation. This cytokine is also reported to play a role in regulating B-cell activation, cytotoxic function of natural killer cells, and immunoglobulin sythesis.
