癌症分泌自身抗体的作用 

1. 促进癌细胞恶变 癌症分泌的自身抗体具有类似于生长因子的作用，直接促进癌细胞的恶变（包括增殖、迁移、侵袭和抗凋亡）。 2. 促进免疫逃逸 癌症分泌的自身抗体，通过特定的糖基化修饰（如Ans162位点的唾液化修饰），可以从促进免疫作用转变为免疫抑制作用。 这些唾液酸化的IgG分子可以通过与树突状细胞上的唾液酸受体DC-SIGN结合，抑制树突状细胞(DCs)和CD4+T细胞的功能。 癌症细胞分泌抗体可以抑制ADCC功能，下调NK细胞的细胞毒活性。 

3.促肿瘤炎症 在脂多糖(LPS)刺激后，癌症分泌IgG显著上调。 癌症来源的IgG，可以通过 TLR4/TRIF/NF-kB 通路刺激肿瘤相关巨噬细胞释放IL-1b来诱导炎症。
