immune system
• sera of mice fail to initiate complement by activating C3 in response to LPS from three different bacteria species
• complement activity is restored when sera is pre-mixed with sera from C3tm1Hrc mice that lack the C3 enzyme
• there is a delayed activation of C3 in mouse sera when low amounts of CVF factor are added
• sera fail to initiate complement to LPS and to erthryocytes from mice that lack the complement inhibitor factor Crry (Cr1ltm1Hmo mice)
• complement induced by yeast wall zymogen is reduced by 1.6-fold
• systemic complement fails to initiate in mice one hour after injection of lipooligosaccharide
• systemic complement is reduced by about 2-fold one hour after injection of LPS
• antibody-mediated complement of sera is intact as measured by C3 activation in the presence of OVA and anti-OVA immunoglobulins
