- So there's no reason why any antigens should still be in your body, right?
所以抗原沒有任何理由會待在你的身體裡，對吧？
- Your red blood cells naturally contain millions of antigens that your immune system doesn't react to, and the antigens that you have in those red blood cells determine your blood type.

- the antibody will dock to the antigen. And when it does that basically it marks the antigens
抗體會綁住抗原。當它綁住抗原時，它對抗原作上了記號

- They form when an infected red blood cell sticks to uninfected red blood cells—a process that's helped along by A and B antigens.
它們在一個受瘧疾感染的紅血球黏合上其他未感染的紅血球時形成，而這個過程需要有 A 抗原與 B 抗原的幫助。
- While scientists still don't fully understand what's going on here, one idea is that having A or B antigens might help prevent the cholera toxin from binding as firmly to some of your cells.
雖然科學家們還沒有完全了解其中機制為何，但有一個想法是，A 或 B 抗原或許會幫忙阻止霍亂毒素與其他細胞緊密結合。
