| Interleukin (IL)-18 was originally discovered as a factor that enhanced IFN-? production from anti-CD3-stimulated Th1 cells, especially in the presence of IL-12. Upon stimulation with Ag plus IL-12, naïve T cells develop into IL-18 receptor (IL-18R) expressing Th1 cells, which increase IFN-? production in response to IL-18 stimulation. |
| Recombinant Human IL-18 Protein is expressed from E.coli without tag. It contains Tyr37-Asp193. |
