Beschreibung:
The interleukin-1beta (IL-1beta) converting enzyme (ICE) processes the inactive IL-1beta precursor to the proinflammatory cytokine. ICE was also shown to cleave the precursor of interferon-gamma inducing factor (IGIF) at the authentic processing site with high efficiency, thereby activating IGIF and facilitating its export. Lipopolysaccharide-activated ICE-deficient (ICE-/-) Kupffer cells synthesized the IGIF precursor but failed to process it into the active form. Interferon-gamma and IGIF were diminished in the sera of ICE-/- mice exposed to Propionibacterium acnes and lipopolysaccharide. The lack of multiple proinflammatory cytokines in ICE-/- mice may account for their protection from septic shock.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Y -- Kuida, K -- Tsutsui, H -- Ku, G -- Hsiao, K -- Fleming, M A -- Hayashi, N -- Higashino, K -- Okamura, H -- Nakanishi, K -- Kurimoto, M -- Tanimoto, T -- Flavell, R A -- Sato, V -- Harding, M W -- Livingston, D J -- Su, M S -- New York, N.Y. -- Science. 1997 Jan 10;275(5297):206-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vertex Pharmaceuticals, Inc., 130 Waverly Street, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8999548" target="_blank"〉PubMed〈/a〉
