Disease relevance of Mbl2

  • Results of the passive hemolysis experiment using sheep erythrocytes coated with yeast mannan suggest that this MBP has the ability to activate complement [1].
  • The objective of this study is to investigate the involvement of MBP in IgA nephropathy by using HIGA mice, which spontaneously develop a glomerulonephritis resembling human IgA nephropathy [2].
  • We have found that MBP recognizes and binds specifically to oligosaccharide ligands expressed on the surfaces of a human colorectal carcinoma [3].
  • Taken together, the data show that MBL modulates the response to HSV-2 in mice by affecting neutralization of the virus [4].
  • CONCLUSIONS: These results indicate that neither MBL nor activation of the complement cascade is crucial for the induction of anaphylaxis [5].

Other interactions of Mbl2

  • The results implicate SP-D and possibly MBL as important components of the innate defense of the respiratory tract against influenza virus and indicate that the degree or pattern of glycosylation of a virus can be an important factor in its virulence [14].
  • These results confirm an essential function for complement in host resistance against S. aureus infection but also identify an MBL-dependent mechanism that is C3 independent [15].

Analytical, diagnostic and therapeutic context of Mbl2

  • Quantitative RT-PCR revealed that the small intestine is a predominant site of extrahepatic expression of L-MBP [10].
  • The mannan-binding protein fraction of bovine serum that eluted with 100 mM mannose from a mannan-Sepharose column was analyzed under reducing conditions by SDS-PAGE [1].
  • The concentration of MBP in serum from normal mice was measured by rocket immunoelectrophoresis and found to be from below 1 microgram/ml to 100 micrograms/ml (average 50 micrograms/ml, n = 60) [13].
  • Kidney damages, which were evaluated by levels of blood urea nitrogen (BUN) and creatinine, showed that MBL DKO mice were significantly protected compared with WT mice [11].
  • Mice subjected to renal I/R displayed evident renal MBL-depositions, depending on the duration of warm ischemia, in the early reperfusion phase [16].
