CD40

Validation Data Figure 1. Detection of CD40 expression in peripheral blood cells of humanized CD40 mice. The FACS results of peripheral blood cells collected from homozygous humanized CD40 mice and wild-type mice showed that the active expression of humanized CD40 was detected in CD19 positive cells collected from homozygous humanized CD40 mice, and its expression level was similar to that of murine Cd40 expression in wild-type mice.

Figure 3. In vivo validation of anti-tumor efficacy in a MC38 tumor-bearing model of humanized CD40 mice. Humanized CD40 mice were inoculated with MC38 colon cancer cells. After the tumors grew to 100 mm3, the animals were randomly assigned into different group (n=8). The results indicated that the antibodies targeting human CD40 showed a very significant antitumor effect (p<0.001). Combination of anti-CD40 and anti-PD-1 is shown more significant anti-Tumor effect. (Data in partnership with collaborators)

Case study 2: In vivo efficacy and safety evaluation of anti-human CD40 antibody using hCD40 mice

I. In vivo anti-tumor effect of an anti-human CD40 antibody in hCD40 mice.

Figure 4. In vivo validation of anti-tumor efficacy in a MC38 tumor-bearing model of humanized CD40 mice. Homozygous humanized CD40 mice were inoculated with MC38 colon cancer cells. The results showed that an anti-human CD40 antibody exerted a very significant anti-tumor effect, demonstrating that the humanized CD40 mice are a good in vivo model for validating the efficacy of antibodies targeting human CD40. Mean volume ± SEM of tumor tissues(A). Mean body weight ± SEM of mice(B).

II. Evaluation of anti-human CD40 toxicity in hCD40 mice.
