In complement system, lectin pathway activates complement by recognition of sugar chains on microbes. MASP has a pivotal role in the lectin pathway. Three MASPs (MASP-1, MASP-2 and MASP-3) were identified. We reported that MASP-1/3 activate complement D factor(fD), which is essential for the alternative pathway. In this study, we will investigate the mechanisms for activation of fD by MASP-1/3. During this study, MASP-1/3 defected patients were found. We found that MASP1/3 is essential for alternative pathway in human as well as mouse.

在补体系统中，凝集素途径通过识别微生物上的糖链来激活补体。MASP在凝集素途径中具有关键作用。鉴定了三种MASP（MASP-1、MASP-2和MASP-3）。我们报道了MASP-1/3激活补体D因子（fD），这是旁路途径所必需的。在本研究中，我们将研究MASP-1/3激活fD的机制。在本研究中，我们发现MASP 1/3在人和小鼠的旁路途径中是必需的。
