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. 


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.


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. 


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.


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.


Target: LIGHT                    

The human LIGHT expression mirrors the murine LIGHT expression. hLIGHT is functional and its stimulation increases T-cell activation in vivo.


Target: CD28                    

The human CD28 expression recapitulates murine CD28 expression. hCD28 is functional: α-human CD28 co-stimulation induces T cell activation and proliferation. 


Target: CD39                    

The human CD39 expression recapitulates murine CD39 expression. hCD39 is functional: α-human CD39 specifically reduces human CD39 activity. 


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.
