Membrane Location

Secreted




Biological Literature Report of Shedding
Substrate Name IL-18
Cell Type
Substrate Description augments natural killer cell activity in spleen cells and stimulates interferon gamma production in T-helper type I cells.
Substrate Function Category Immune and Inflammation
Substrate Function Subtype
Sheddase caspase-1
Shedding-related Disease cytokine
Short Summary of Papers LPS stimulation of macrophages induced shedding and release of membrane-bound form of IL-18 (mIL-18). sIL-18 secretion by macrophages could depend on the protease-mediated shedding of its membrane-bound form.
