Mannose-binding lectins are produced by a healthy immune system, for the purpose of breaking apart glycoproteins that enable many viruses, certain bacteria, and some yeasts to hide from . Common symptoms. Binding at the opposite end of the lectin domain, mannose stabilizes the narrow mannose-binding pocket and can stabilize the fully active state of the lectin domain.

As local levels of C3b increase, C3b associates with C3bBb to form C3bBbC3b, the C5 convertase of the AP. An almost 6-fold average increase in the percentage of cells infected was observed for 8 independent donors (p = 0.005). One mechanism by which MBL could increase cytokine response is through activation of complement via the lectin pathway. Summary. 1996.
