In vivo Efficacy Evaluation of Anti-hTNFR2 in TNFR2 HuGEMM Mice with MC38-OVA Tumors

Landingpage-ASHU-190010-TNFRSF1B-HU-ICPMouse-6.01

Figure 4. In vivo anti-tumor effect of anti-TNFRSF1B antibody, in a humanized mouse model of TNFRSF1B In vivo validation of anti-tumor efficacy in a MC38-OVA tumor-bearing model of humanized TNFRSF1B mice. Homozygous humanized TNFRSF1B mice were inoculated with MC38 colon cancer cells. The drug targeting human TNFRSF1B, showed a very significant anti-tumor effect, demonstrating that the humanized TNFRSF1B mice are a good in vivo model for validating the efficacy of antibodies targeting human TNFRSF1B.

FACS for Blood upon TNFR2 Antagonist Treatment

Landingpage-ASHU-190010-TNFRSF1B-HU-ICPMouse-7.01

Figure 5. FACS for blood upon TNFRSF1B antagonist treatment. Addition of antagonistic hTNFRSF1B antibody can impair hTNF-induced Treg cells proliferation, while the agonistic hTNFRSF1B antibody alone can induce a modest proliferative response. (Data in partnership with collaborators)
