Anti-CD46 (3G7HY)-CD3ζ CAR-MA (CARMA-W2019)


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

The vector of anti-CD46 chimeric antigen receptor (CAR) is constructed for the engineering of macrophage cells to target human CD46 and induce target cell phagocytosis. The macrophage cells are genetically modified through transduction with a lentiviral vector expressing scFv of anti-CD46 antibody (3G7HY) linked to CD3ζ signaling domains. The vector product was designed for the treatment of Colorectal cancer.

  • 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.

  • CD46 molecule
  • Introduction
  • The protein encoded by this gene is a type I membrane protein and is a regulatory part of the complement system. The encoded protein has cofactor activity for inactivation of complement components C3b and C4b by serum factor I, which protects the host cell from damage by complement. In addition, the encoded protein can act as a receptor for the Edmonston strain of measles virus, human herpesvirus-6, and type IV pili of pathogenic Neisseria. Finally, the protein encoded by this gene may be involved in the fusion of the spermatozoa with the oocyte during fertilization. Mutations at this locus have been associated with susceptibility to hemolytic uremic syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.
  • Alternative Names
  • CD46; CD46 molecule; MCP; TLX; AHUS2; MIC10; TRA2.10
