Anti-SLC4A1 KIR CAR (XW-823) Vector (XS-1122-YF823)


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

The vector of anti-SLC4A1 KIR chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target Mouse SLC4A1. The T cells are genetically modified through transduction with a lentiviral vector expressing scFv (XW-823) of anti-SLC4A1 antibody linked to KIR2DS2 TM & ICD and DAP12. The vector product was designed for the discovery and development of cellular therapy against Renal 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 part of the anion exchanger (AE) family and is expressed in the erythrocyte plasma membrane, where it functions as a chloride/bicarbonate exchanger involved in carbon dioxide transport from tissues to lungs. The protein comprises two domains that are structurally and functionally distinct. The N-terminal 40kDa domain is located in the cytoplasm and acts as an attachment site for the red cell skeleton by binding ankyrin. The glycosylated C-terminal membrane-associated domain contains 12-14 membrane spanning segments and carries out the stilbene disulphonate-sensitive exchange transport of anions. The cytoplasmic tail at the extreme C-terminus of the membrane domain binds carbonic anhydrase II. The encoded protein associates with the red cell membrane protein glycophorin A and this association promotes the correct folding and translocation of the exchanger. This protein is predominantly dimeric but forms tetramers in the presence of ankyrin. Many mutations in this gene are known in man, and these mutations can lead to two types of disease: destabilization of red cell membrane leading to hereditary spherocytosis, and defective kidney acid secretion leading to distal renal tubular acidosis. Other mutations that do not give rise to disease result in novel blood group antigens, which form the Diego blood group system. Southeast Asian ovalocytosis (SAO, Melanesian ovalocytosis) results from the heterozygous presence of a deletion in the encoded protein and is common in areas where Plasmodium falciparum malaria is endemic. One null mutation in this gene is known, resulting in very severe anemia and nephrocalcinosis.
