immune system
|
• antibody-mediated complement of sera is severely impaired as measured by C3 activation in the presence of OVA and anti-OVA immunoglobulins
|
|
• mice show some protection from intranasal infection with the mouse-adapted SARS-CoV MA15 , showing less weight loss than in wild-type controls, but more weight loss than in C3tm1Crr homozygotes

|
|
immune system
|
• total hemolytic complement activation was reduced 50% in mutant sera
|
|
• serum from mutant mice showed no evidence of C3 deposition on zymosan
• serum from mutant mice did not support in vitro cleavage of C3 by cobra venom factor
• alternative pathway-dependent hemolytic activity was undetectable in mutant serum
|
reproductive system
|
• partial penetrance; only seen in mice derived from one of four ES cell clones
• this effect is most evident in the F1 generation and it appears to be lost upon breeding to the C57BL/6 strain

normal phenotype
|
• at 2 months of age, double homozygotes have normal amounts of plasma C3, with no evidence of capillary wall glomerular C3 deposition and subendothelial electron-dense deposits
• unlike Cfhtm1Mbo mice, double homozygotes show normal kidney histology and function with no evidence of GBM abnormalities at 8 months of age
• also unlike Cfhtm1Mbo mice which develop severe renal disease within 5 days of receiving sheep nephrotoxic serum (NTS), double homozygotes remain healthy at this stage
