In response, the body generates IgG antibodies that target the abnormally glycosylated residues.

在免疫应答下，机体产生针对异常糖基化残基的IgG抗体。

Now these glycosylated IgA1 antibodies are identified by the body and degraded IgA when too much of it accumulates.

这些糖基化的IgA1被机体识别，在其数量过多时被降解。

Among these are serine and threonine residues which are O-linked glycosylated, meaning they have a sugar molecule, specifically galactose, attached to their oxygen.

其中有丝氨酸和苏氨酸残基，是o链糖基化的，这意味着它们的氧上有一个糖分子，半乳糖居多。
