When these anti-glycan IgG antibodies bind to abnormal IgA1, immune complexes are formed.

当这些抗糖基化的IgG抗体与异常IgA1结合，形成免疫复合物。

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。

Meanwhile, IgG antibodies circulate for an extended period after infection;their presence usually indicates that someone was exposed and recovered.

同时，IgG抗体在感染后会循环很长时间，它们的存在通常表明有人被感染并康复。

Immunoassays may detect IgG antibodies, the most abundant class, and IgM antibodies, the type that's first produced in response to a new infection.

免疫测定可以检测 IgG 抗体（最丰富的一类）和 IgM 抗体（应对新感染而首先产生的抗体）。
