cardiovascular system
• left ventricle contractile dysfunction and myocardial necrosis is more pronounced in isolated perfused hearts during reperfusion after ischemia than in wild-type hearts but less than in homozygous Cd74tm1Eae hearts
• infract size is greater in isolated perfused hearts during reperfusion after ischemia than in wild-type hearts but is smaller than in homozygous Cd74tm1Eae hearts

immune system
• mutants stimulated with LPS or SEB show a 50% and 65%, respectively, reduction in the plasma levels of TNF-alpha compared to wild-type
• macrophages stimulated with LPS and interferon gamma show diminished production of TNF-alpha
• lymph node cells from L. major infected mice show higher IL-4 production after antigen stimulation than cells from wild-type
• mutants are resistant to the lethal effects of high dose bacterial lipopolysaccharide (LPS) and Staphylococcus aureus enterotoxin B (SEB) with D-galactosamine
• however, mutants are susceptible to a combination of low-dose LPS and D-galactosamine
• mutants clear gram-negative bacteria Pseudomonas aeruginosa instilled into the trachea better than wild-type and have diminished neutrophil accumulation in their bronchoalveolar fluid compared to wild-type
• mice are more susceptible to the intracellular parasite L. major than wild-type

homeostasis/metabolism
• left ventricle contractile dysfunction and myocardial necrosis is more pronounced in isolated perfused hearts during reperfusion after ischemia than in wild-type hearts but less than in homozygous Cd74tm1Eae hearts
• infract size is greater in isolated perfused hearts during reperfusion after ischemia than in wild-type hearts but is smaller than in homozygous Cd74tm1Eae hearts
• mutants stimulated with LPS or SEB show a 50% and 65%, respectively, reduction in the plasma levels of TNF-alpha compared to wild-type
• macrophages stimulated with LPS and interferon gamma show diminished production of TNF-alpha
