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

The vector of anti-CD171 KIR chimeric antigen receptor (CAR) is constructed for the engineering of T cells to target Human CD171. The T cells are genetically modified through transduction with a lentiviral vector expressing scFv (XW-604) of anti-CD171 antibody linked to KIR2DS2 TM & ICD and DAP12. The vector product was designed for the discovery and development of cellular therapy against Ovarian 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 an axonal glycoprotein belonging to the immunoglobulin supergene family. The ectodomain, consisting of several immunoglobulin-like domains and fibronectin-like repeats (type III), is linked via a single transmembrane sequence to a conserved cytoplasmic domain. This cell adhesion molecule plays an important role in nervous system development, including neuronal migration and differentiation. Mutations in the gene cause X-linked neurological syndromes known as CRASH (corpus callosum hypoplasia, retardation, aphasia, spastic paraplegia and hydrocephalus). Alternative splicing of this gene results in multiple transcript variants, some of which include an alternate exon that is considered to be specific to neurons.
