mortality/aging
• following treatment with high doses of recombinant mouse TNF (mTNF), mice are totally protected from mTNF-induced lethality, unlike wild-type controls
|
immune system
• at 6 hours after mTNF injection, serum concentration of IL-6 is significantly lower than that in wild-type controls
|
• at 6 hours after mTNF injection, mice exhibit significantly reduced IL-6 mRNA levels in the spleen and small intestine, but not in liver, relative to wild-type controls
|
• mice are totally resistant to mTNF-induced lethality and hypothermia, unlike wild-type controls
• however, mTNF-induced systemic necroptosis is unaffected, as determined by tissue damage markers (including ALT, LDH, and mitochondrial gene expression) in the serum at 6 hours after mTNF injection
|
homeostasis/metabolism
• at 6 hours after mTNF injection, serum concentration of IL-6 is significantly lower than that in wild-type controls
