Anti-EGFR (MR1)-FcRɣ CAR THP1 (CARTHP-W0449)

 Datasheet

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

The anti-EGFR chimeric antigen receptor (CAR) THP1 cell line is a stable cell line developed using anti-EGFR CAR lentivirus transfection. This transfected CAR lentiviral vector is constructed to express a scfv of anti-EGFR antibody (MR1) linked to FcRɣ signaling domains.The anti-EGFR 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 NSCLC, GBM, sarcoma, malignant pleural mesothelioma (MPM), retinoblastoma, glioma, medulloblastoma, osteosarcoma, Ewing sarcoma.

Details

  • Target
  • EGFR
  • 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
  • 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
  • Epidermal growth factor receptor
  • Introduction
  • The protein encoded by this gene is a transmembrane glycoprotein that is a member of the protein kinase superfamily. This protein is a receptor for members of the epidermal growth factor family. EGFR is a cell surface protein that binds to epidermal growth factor, thus inducing receptor dimerization and tyrosine autophosphorylation leading to cell proliferation. Mutations in this gene are associated with lung cancer. EGFR is a component of the cytokine storm which contributes to a severe form of Coronavirus Disease 2019 (COVID-19) resulting from infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).
  • Alternative Names
  • ERBB; ERRP; HER1; mENA; ERBB1; PIG61; NISBD2; EGFR; Epidermal growth factor receptor
