Anti-FRα (Farletuzumab)-FcRɣ CAR-MA (CARMA-W0773)

Online Inquiry  Datasheet

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

The vector of anti-FRα chimeric antigen receptor (CAR) is constructed for the engineering of macrophage cells to target human FRα and induce target cell phagocytosis. The macrophage cells are genetically modified through transduction with a lentiviral vector expressing scFv of anti-FRα antibody (Farletuzumab) linked to FcRɣ signaling domains. The vector product was designed for the treatment of Ovarian, urothelial bladder carcinoma.

  • Discription of Signaling Cassetes
  • FcRɣ:
    FcRɣ is used as the CAR intracellular signaling domain. As a phagocytosis receptor, FcRɣ has cytosolic Immunoreceptor Tyrosine-based Activation Motifs (ITAMs) that are phosphorylated by Src family kinases. Based on this mechanism, FcRɣ signaling can induce macrophage phagocytosis which has been demonstrated in the published article.
    Fc gamma receptors belong to the group of non-catalytic tyrosine-phosphorylated receptors which share a similar signalling pathway involving phosphorylation of tyrosine residues. The receptors generate signals within their cells through an important activation motif known as an immunoreceptor tyrosine-based activation motif (ITAM). An ITAM is present in the intracellular tail of FcγRIIA, and its phosphorylation induces phagocytosis in macrophages. FcγRI and FcγRIIIA do not have an ITAM but can transmit an activating signal to their phagocytes by interacting with another protein that does. This adaptor protein is called the Fcγ subunit and, like FcγRIIA, contains the two YXXL sequences that are characteristic of an ITAM.

  • Gene Name
  • Folate receptor alpha
  • Introduction
  • The protein encoded by this gene is a member of the folate receptor family. Members of this gene family bind folic acid and its reduced derivatives, and transport 5-methyltetrahydrofolate into cells. This gene product is a secreted protein that either anchors to membranes via a glycosyl-phosphatidylinositol linkage or exists in a soluble form. Mutations in this gene have been associated with neurodegeneration due to cerebral folate transport deficiency. Due to the presence of two promoters, multiple transcription start sites, and alternative splicing, multiple transcript variants encoding the same protein have been found for this gene.
  • Alternative Names
  • FBP; FOLR; NCFTD; FRalpha; FOLR1; Folate receptor alpha
