PelB-IL10- His

This composite part is made with the basic parts Pectate Lyase B (PelB) (BBa_K2302005), Interleukin 10 (IL-10) (BBa_K554004), and Polyhistadine-tag (His-tag) (BBa_K3630006). This forms the construct PelB-IL10-His. The TU Eindhoven 2023 team used it as a therapeutic against Inflammatory Bowel disease (IBD).

IL-10 is important for regulating inflammation. It is immunosuppressive with effect on macrophages and dendritic cells. Animal studies show that mice with IL-10 deficiency develop severe colitis, but not when recombinant IL-10 is systemically applied. With the anti-inflammatory effect of IL-10, it can be used to treat IBD and other autoimmune disorders. However, an oral intake or injection with only IL-10 induces side effects. The options are also limited because of the acid sensitivity of IL-10. Genetically modified organisms are an alternative for delivering IL-10 at the right place of the inflammation. In our case with E.coli BL21 cells as carrier.

For the expression of IL-10 by E.coli, a signal sequence is needed for the efficient production with the Sec secretion pathway. This is why PelB is added to IL-10. On the other side of IL-10, we added a His-tag. This ...
