Disease relevance of Cd55

  • Compared with wild-type mice, Daf1(-/-) mice also displayed markedly exacerbated disease progression and pathology in a T cell-dependent experimental autoimmune encephalomyelitis (EAE) model [1].
  • Baseline albuminuria in the Daf1(-/-), CD59a(-/-), and Daf1(-/-)CD59a(-/-) mice was 82, 83, and 139 as compared with 92 microg/mg creatinine in the WT controls (p > 0.1) [2].
  • We induced nephrotoxic serum (NTS) nephritis in Daf1(-/-), CD59a(-/-), Daf1(-/-)CD59a(-/-), and wild-type (WT) mice by administering NTS IgG [2].
  • Seven days after consuming 3% dextran sulfate sodium in their drinking water, Daf1(-/-) mice suffered markedly greater weight loss (-24.7 +/- 7.5% vs -14.2% +/- 4.9%), exhibited uniformly bloody diarrhea as compared with soft stool in control mice, developed shortened colons, and had larger spleens [3].

Biological context of Cd55

 

Anatomical context of Cd55

 

Associations of Cd55 with chemical compounds

  • This contrasted with marked deposition of both C3 and C9 in Daf1(-/-)CD59a(-/-) and Daf1(-/-) mice, which was evident as early as 2 h post-NTS injection [2].
  • Furthermore, the regulation of uterine DAF expression by estrogen is limited to the GPI DAF gene [9].
 

Other interactions of Cd55

  • In mice, both GPI-anchored and transmembrane-anchored DAF proteins are produced, each of which can be derived from two different genes (Daf1 and Daf2) [8].
 

Analytical, diagnostic and therapeutic context of Cd55

  • Electron microscopy demonstrated markedly greater junctional damage in the Daf1(-/-) mice compared with the Daf1(+/+) littermates [10].
  • Molecular cloning of mouse decay accelerating factor (DAF; CD55) predicted two forms of the molecule, one transmembrane (TM) and the other glycosylphosphatidylinositol (GPI)-anchored; these are encoded by separate genes termed Daf-GPI and Daf-TM [11].
  • Northern blot analysis indicated that rat GPI-DAF mRNA was present in all tissues examined except for liver, while rat TM-DAF mRNA was preferentially expressed in testis [12].
  • At 48h, Daf1(-/-) were significantly weaker than CD59a(-/-) and WT mice, and for these mice immunohistochemistry revealed marked C9 deposition at postsynaptic junctions, radioimmunoassays showed reductions in AChR levels, and electron microscopy demonstrated massive junctional damage [13].
