Background
Interleukin 18 (IL-18) is a 18 kDa
cytokine which identified as a costimulatory factor for
production of interferon-gamma (IFN-gamma ) in response to toxic
shock and shares functional similarities with IL-12. IL-18
is synthesized as a precursor 24 kDa molecule without a
signal peptide and must be cleaved to produce an active
molecule. IL-1 converting enzyme (ICE, Caspase-1)
cleaves pro-IL-18 at aspartic acid in the P1 position,
producing the mature, bioactive peptide that is readily
released from the cells. It is reported that IL-18 is
produced from Kupffer cells, activated macrophages,
keratinocytes, intestinal epithelial cells, osteoblasts,
adrenal cortex cells and murine diencephalon. IFN-gamma is
produced by activated T or NK cells and plays critical
roles in the defense against microbiral pathogens. IFN-gamma
activates macrophages, enhances NK activity and B cell
maturation, proliferation and Ig secretion, induces MHC
class I and II antigens, and inhibits osteoclast activation.
IL-18 acts on T helper type-1 (Th1) T cells and in
combination with IL-12 strongly induces them to produce
IFN-gamma . Pleiotropic effects of IL-18 has also been reported,
such as, enhancement production of IFN-gamma and GM-CSF
in peripheral blood mononuclear cells, production of Th1
cytokines, IL-2, GM-CSF and IFN-gamma in T cells,
enhancement of Fas ligand expression by Th1 cells.
