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

The anti-FRα chimeric antigen receptor (CAR) THP1 cell line is a stable cell line developed using anti-FRα CAR lentivirus transfection. This transfected CAR lentiviral vector is constructed to express a scfv of anti-FRα antibody (LK26) linked to Megf10 signaling domains.The anti-FRα CAR engineered THP1 cells can be used to be differentiated into macrophage cells for in vitro or in vivo phagocytosis studies. This CAR-THP1 cell line product can be used for the researches of Ovarian, urothelial bladder carcinoma.

Details

  • Target
  • FRα
  • Cell Type
  • THP1
  • Cell Background
  • THP-1 is a human leukemia monocytic cell line, which has been extensively used to study monocyte/macrophage functions, mechanisms, signaling pathways, and nutrient and drug transport. This cell line has become a common model to estimate modulation of monocyte and macrophage activities. CAR engineered THP1 cells can be differentiated into macrophages using PMA (Phorbol 12-myristate 13-acetate). Once differentiated (M0 macrophages), they were incubated with IL-4 and IL-13 in order to obtain M2 polarized macrophages or with IFN-gamma and LPS for classical macrophage activation (M1).

  • Discription of Signaling Cassetes
  • Megf10:
    Megf10 is used as the CAR intracellular signaling domain. As a phagocytosis receptor, Megf10 has cytosolic Immunoreceptor Tyrosine-based Activation Motifs (ITAMs) that are phosphorylated by Src family kinases. Based on this mechanism, Megf10 signaling can induce macrophage phagocytosis which has been demonstrated in the published article.
    It is a membrane receptor involved in phagocytosis by macrophages and astrocytes of apoptotic cells. It's a receptor for C1q, an eat-me signal, that binds phosphatidylserine expressed on the surface of apoptotic cells

  • 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
