It's bacterial—so you're going to get an immune response, immune surveillance from it.

这种酶是细菌性的—因此首当其冲是获得这种细菌免疫，从中获得免疫监控。

This sort of activity at wound sites might normally draw the attention of the immune system, but that does not happen because platelets carry special proteins in their membranes which render them invisible to immune surveillance.

通常情况下，伤口部位的这种活动可能会引起免疫系统的注意，但这种情况并不会发生，因为血小板膜中携带特殊的蛋白质，使它们不受免疫监控。
