Fig.1 Detection of TNFRSF1B expression by RT-PCR. 

Wild type: only one band at 247 bp with primers F2/R2(mTnfrsf1b);

Homozygous: only one band at 255 bp with primers F1/R1(hTNFRSF1B); 

Abbr.. M, DNA marker; HO, homozygous; HE, heterozygous; WT, wild type.

Fig.7 In vivo efficacy evaluation of anti-hTNFR2 in TNFR2 HuGEMM mice with MC38-OVA tumors.（In collaboration with CrownBio）

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.

Addition of antagonistic hTNFRSF1B antibody can impair hTNF-induced Treg cells proliferation, while the agonistic hTNFRSF1B antibody alone can induce a modest proliferative response.

1 tumor in hTNFR2 Ab1 treatment group decreased  (1/7, TV=0)

2 tumors in hTNFR2 Ab2 treatment group decreased  (2/7, TV=0; 3/7 died during dosing period)
