Humanized Immune Checkpoint (ICP) Mouse Models
Therapies targeting immune checkpoints (ICPs) are changing the practice of medical oncology. genOway has developed a catalog of reliable and efficient translational mouse models for immunotherapy expressing humanized immune checkpoints.
Applications
These models are suitable to assess the efficacy of immuno-oncology compounds targeting immune checkpoints in fully immunocompetent mice. Moreover, they represent a powerful model system for studying how compounds modulate immune cell response and/or stroma cells in a physiological microenvironment.
- Cohorts available upon request
- Studies can be carried out at your site or at your favorite CRO
- SOPF certification and worldwide delivery by professional breeders
- Models provided with FTO on patent-protected technologies used for model generation
Model features
- Physiological expression of the human target(s)
- Preservation of the target-ligand interaction
- Fully functional mouse immune system
- Lack of expression of the murine target gene, thus avoiding cross-reactivity
-
Suitable for studying:
- Well-calibrated syngeneic tumor models
- Long-term treatment(s)
- T cell exhaustion and reminiscence
Model validation
The ICP mouse models are co-validated by our partners of the precompetitive consortium, including BMS, Charles River, Alligator and more company leaders in immuno-oncology and immunotherapy.

Single-targeted immune checkpoint mouse models
|
Target: PD‑1 The humanized PD-1 mouse model (hPD-1) expresses human PD-1 instead of murine PD-1 while the regulation of PD-1 expression is kept under the mouse promoter. The anti-tumor effect induced by anti-hPD-1 antibody pembrolizumab is shown using our model. Learn more |
|
Target: CTLA-4 The human CTLA-4 expression recapitulates the mouse CTLA-4 expression on T cells. An anti-tumor response, induced by anti-hCTLA-4 ipilimumab, is observed in hCTLA-4-expressing mice. Learn more |
|
Target: VISTA The human VISTA expression pattern in homozygous mice is similar to murine VISTA in wild-type mice. Moreover, the model has been shown to be functional in vivo, because the combination of anti-hVISTA and anti-mPD-1 therapies increases survival in a MC38 tumor model. Learn more |
|
Target: OX40 The human OX40 expression mirrors the murine OX40 expression. hOX40 is functional and hOX40L induces increased T-cell proliferation in vitro. Furthermore, anti-tumor effect induced by an anti-hOX40 antibody (BMS 986178 analog) was observed in a MC38 tumor model. Learn more |
|
Target: GITR hGITR is detected on activated splenocytes and tumor-infiltrating lymphocytes (TILs). The model is functional as it has been used to show the anti-tumor effect of an anti-hGITR antibody. Learn more |
|
Target: LIGHT The human LIGHT expression mirrors the murine LIGHT expression. hLIGHT is functional and its stimulation increases T-cell activation in vivo. Learn more |
|
Target: CD28 The human CD28 expression recapitulates murine CD28 expression. hCD28 is functional: α-human CD28 co-stimulation induces T cell activation and proliferation. Learn more |
|
Target: CD39 The human CD39 expression recapitulates murine CD39 expression. hCD39 is functional: α-human CD39 specifically reduces human CD39 activity.Learn more |
|
Target: STING The humanized STING model, developed by Knockin at the mouse STING locus, expresses a full human STING. hSTING is functional: Agonists induce cytokine release in vivo. Learn more |
Double-targeted immune checkpoint mouse models
|
Target: PD‑1 & TIM3 The double-humanized PD-1/TIML3 mouse model (hPD-1/hTIM3) expresses human PD-1 and human TIM3 instead of murine proteins while its regulation is kept under the mouse promoter. This model was generated by intercrossing hPD-1 and hTIM3 mice. Learn more |
|
Target: PD‑1 & VISTA The double-humanized PD-1/VISTA mouse model (hPD-1/hVISTA) expresses human PD-1 and VISTA instead of murine proteins while its regulation is kept under the mouse promoter. This model was generated by intercrossing hPD-1 and hVISTA mice. Learn more |
|
Target: PD‑1 & CTLA-4 The double-humanized PD-1/CTLA-4 mouse model (hPD-1/hCTLA-4) expresses human PD-1 and CTLA-4 instead of murine proteins while its regulation is kept under the mouse promoter. This model was generated by intercrossing hPD-1 and hCTLA-4 mice. Learn more |
|
Target: CTLA-4 & LAG3 The double-humanized CTLA-4/LAG3 mouse model (hCTLA-4/hLAG3) expresses human CTLA-4 and LAG3 instead of murine proteins while its regulation is kept under the mouse promoter. This model was generated by intercrossing hCTLA-4 and hLAG3 mice. Learn more |
|
Target: GITR & Foxp3 hGITR mice were crossed with Foxp3-IRES-mRFP (FIR) reporter mice to monitor Treg activity. The FIR's bicistronic reporter expressing a red fluorescent protein has been knocked into the endogenous Foxp3 locus and faithfully mirrors Foxp3 expression. Learn more |
|
Target: GITR & GITRL The double-humanized GITR/GITRL mouse model (hGITR/hGITRL) expresses both human GITR and GITRL instead of their corresponding murine proteins. Both genes are under endogenous mouse promoters. This model was generated by intercrossing hGITR and hGITRL mice. Learn more |
