Masp2tm1Wjsc/Masp2tm1Wjsc mice exhibit reduced myocardial ischemia/reperfusion injury-induced myocardial damage

homeostasis/metabolism
decreased susceptibility to injury ( J:172218 )
• significant protection from gastrointestinal ischemia/reperfusion injury
decreased myocardial infarct size ( J:172218 )
• significant reduction in myocardial ischemia/reperfusion injury-induced myocardial damage

immune system
impaired lectin complement pathway ( J:172218 )
• total absence of lectin pathway-dependent C4 cleavage on mannan- and zymosan-coated surfaces

cardiovascular system
decreased myocardial infarct size ( J:172218 )
• significant reduction in myocardial ischemia/reperfusion injury-induced myocardial damage
