Online Inquiry  Datasheet

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

The anti-B7-H3 chimeric antigen receptor (CAR) THP1 cell line is a stable cell line developed using anti-B7-H3 CAR lentivirus transfection. This transfected CAR lentiviral vector is constructed to express a scfv of anti-B7-H3 antibody (BRCA69D) linked to CD3ζ signaling domains.The anti-B7-H3 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 Glioblastoma, Ovarian cancer.

Details

  • Target
  • B7-H3
  • 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
  • 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_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
  • CD276 molecule
  • Introduction
  • The protein encoded by this gene belongs to the immunoglobulin superfamily, and thought to participate in the regulation of T-cell-mediated immune response. Studies show that while the transcript of this gene is ubiquitously expressed in normal tissues and solid tumors, the protein is preferentially expressed only in tumor tissues. Additionally, it was observed that the 3' UTR of this transcript contains a target site for miR29 microRNA, and there is an inverse correlation between the expression of this protein and miR29 levels, suggesting regulation of expression of this gene product by miR29. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
  • Alternative Names
  • CD276; CD276 molecule; B7H3; B7-H3; B7RP-2; 4Ig-B7-H3
