Preclinical Humanized PD-1 Mouse Model

Humanized Immune Checkpoint Mouse Models

Design of the hPD‑1 mouse

The humanized PD‑1 mouse model (hPD-1) has been developed by inserting, within the mouse PD-1 locus, a chimeric PD-1 with a human extracellular domain, a murine transmembrane domain and a murine intracellular domain.

Applications in immuno-oncology

The hPD-1 mouse enables the in vivo efficacy assessment and profiling of immuno-oncology agents targeting the human immune checkpoint PD-1 in fully immunocompetent mice.

Humanized tumor cell line MC38-hPD-L1:
Use our hPD-1 mouse model together with our cell line MC38-hPD-L1 as a syngeneic tumor model for testing the efficacy of combination therapies targeting human PD-1 and human PD-L1.

hPD-1 features

  • The PD-1 extracellular domain is entirely humanized
  • Physiological regulation and expression pattern of the human PD-1
  • Preservation of the target-ligand interaction
  • Fully functional mouse immune system
  • Lack of expression of the murine target gene, thus avoiding cross-reactivity

hPD-1 validation*

The model has been co-validated by Charles River, our partner of the precompetitive consortium of company leaders in immuno-oncology and immunotherapy.

A scientific poster was presented at the Tumour Models 2019 in Boston. Download poster
