They found that immunoglobulin E didn't react to the PLA2—until it started hurting cells.

他们发现免疫球蛋白 E 对 PLA2 没有反应——直到它开始伤害细胞。

In tissues like the gut, the skin, and the respiratory system, the antibody called immunoglobulin E, or IgE, binds to white blood cells called mast cells.

在肠道、皮肤和呼吸系统等组织中，称为免疫球蛋白 E 或 IgE 的抗体与称为肥大细胞的白细胞结合。

When it gets there, it passes pieces of the allergen onto even more immune cells, so that they can work together to form an antibody called immunoglobulin E.

当它到达那里时， 它将过敏原的片段传递给更多的免疫细胞，这样它们就可以一起工作形成一种叫做免疫球蛋白 E 的抗体。
