Anti-Claudin 18.2 (Zolbetuximab)-CD3ζ CAR-MA (CARMA-W1449)


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

The vector of anti-Claudin 18.2 chimeric antigen receptor (CAR) is constructed for the engineering of macrophage cells to target human Claudin 18.2 and induce target cell phagocytosis. The macrophage cells are genetically modified through transduction with a lentiviral vector expressing scFv of anti-Claudin 18.2 antibody (Zolbetuximab) linked to CD3ζ signaling domains. The vector product was designed for the treatment of Advanced solid tumor.

  • Discription of Signaling Cassetes
  • CD3ζ:
    CD3ζ is used as the CAR intracellular signaling domain. CD3ζ has homology to the Fc common γ-chain, FcεRI-γ, a canonical signaling molecule for antibody_x005f_x005f_x005F_x0002_dependent cellular phagocytosis (ADCP) in macrophages. CD3ζ, also known as T-cell receptor zeta, which together with T-cell receptor and CD3γ, δ , ε chain, forms the TCR-CD3 complex. ζ was expressed independently from the complex. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. CD3-zeta, which contains 3 ITAMs, is the most commonly used endodomain component of CARs. It transmits an activation signal to the T cell after antigen is bound. CD3-zeta may not provide a fully competent activation signal and additional co-stimulatory signaling is needed. For example, chimeric CD28 and OX40 can be used with CD3-zeta to transmit a proliferative/survival signal, or all three can be used together.

  • Gene Name
  • Claudin 18
  • Introduction
  • This gene encodes a member of the claudin family. Claudins are integral membrane proteins and components of tight junction strands. Tight junction strands serve as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets, and also play critical roles in maintaining cell polarity and signal transductions. This gene is upregulated in patients with ulcerative colitis and highly overexpressed in infiltrating ductal adenocarcinomas. PKC/MAPK/AP-1 (protein kinase C/mitogen-activated protein kinase/activator protein-1) dependent pathway regulates the expression of this gene in gastric cells. Alternatively spliced transcript variants encoding different isoforms have been identified.
  • Alternative Names
  • SFTA5; SFTPJ; CLDN18; claudin 18; CLDN18.2; Claudin 18.2
