Applications of the genO‑hIgE/hFcεR1 mouse model

Useful applications for researchers working in immuno-inflammation and allergic diseases: 

  • Assess the efficacy of IgE-targeting therapeutics
    • Test therapeutics that block anaphylaxis (passive or active) and help controling asthma
  • Develop models of Passive Cutaneous Anaphylaxis (PCA), OVA hypersensitivity and Passive systemic anaphylaxis (PSA)
  • Investigate the mode of action (MoA) of various compounds and understand their therapeutic potential

 

 Features

  • Human-like cellular distribution (i.e., mast cells, basophils, monocytes/DCs, Langerhans cells, and eosinophils) of the FcεR1 receptor
  • Physiological regulation and expression of the chimeric IgE/FcεR1 complex
  • Preservation of ligand-receptor interaction
  • Preservation of the Ig class switching mechanism
  • Human IgE is present, but at low levels
  • Fully functional mouse immune system
  • Lack of expression of the murine target genes
