Design of the genO‑hPD-1/hCTLA-4 mouse
The double-humanized genO‑hPD-1/hCTLA-4 mouse model was generated by intercrossing genO-hPD-1 and genO-hCTLA-4 mice.
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. The design of hCTLA-4, developed by Knockin at the mouse CTLA-4 locus, enables the expression of: a) the full-length chimeric CTLA-4 isoform (human extracellular domain and mouse intracellular domain); and b) the soluble isoform (human extracellular domain).
Both hPD-1 and hCTLA-4 expressions are regulated by endogenous mouse promoters.
Features
- The PD-1 and CTLA-4 extracellular domains are entirely humanized
- Physiological regulation and expression pattern of the human PD-1 and CTLA-4
- Preservation of the target-ligand interaction
- Fully functional mouse immune system
- Lack of expression of the murine target gene, thus avoiding cross-reactivity
