| − | We inserted this part into plasmid pCDFDuet-1. So the expression of this part can be induced by IPTG. We transformed the IL10-flag plasmid into BL21, and incubated at 37 ℃ overnight to dilute to OD = 0.2. After 2 h of growth at 37 ℃, IPTG was added and induced at 30 ℃ for 16 h. Then, the bacterial solution was lysed and the expression of IL10 was detected by western blot (Figure 1). We used the human IL10 sequence optimized by E. coli from the previous iGEM team (the original part is BBa_K554004). So we have reason to believe that we have successfully expressed IL10. As a widely validated and used cytokine, we believe it can play an immunosuppressive role in vivo.

IL10-flag
Interleukin-10 is a natural immunosuppressive cytokine that is normally released by regulatory T cells and plays an important role in intestinal homeostasis. In our engineered bacteria, we hope to induce the release of interleukin-10 through the inflammatory signal nitric oxide to achieve drug release controllability.
