背景(Background)

Interleukin (IL)-18 was originally discovered as a factor that enhanced IFN-γ 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-γ production in response to IL-18 stimulation.

分子别名(Synonyms)

IL-18; IL18; IGIF; IL-1F4; IL-1 gamma; IL1F4; IL-1g; Interleukin 1
