人體免疫系統大揭密！ (The Immune System)
- 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
- mediated response. And so basically we can fight those antigens out here in the humers
我們還稍微滅活他們。但是如果你看這裡，這殺傷性T細胞
為什麼血型這麼多？原來每一種都有「隱藏超能力」！ (Every Hidden Advantage of Your Blood Type Explained)
- The absence of A and B antigens reduces the ability of Plasmodium falciparum, the parasite responsible for the deadliest form of malaria, to cause red blood cells to clump together, lowering the risk of severe malaria in O carriers.
缺乏A抗原和B抗原，降低了惡性瘧原蟲（導致最致命瘧疾的寄生蟲）讓紅血球聚集的能力，降低了O型帶原者罹患嚴重瘧疾的風險。
- Its defining feature is the presence of A antigens and the RHD factor on the surface of red blood cells, which means A positive individuals can safely receive blood from both A and O positive donors.
A型血的特徵是紅血球表面同時帶有A抗原和Rh陽性因子，這表示A型陽性者可以安全地接受A型和O型陽性者的輸血。
超過十幾種疫苗！為什麼兒童要接種這麼多疫苗？ (Why children get so many vaccines)
- We are exposed to thousands and thousands of antigens.
我們會接觸到成千上萬種抗原。
- Our body and our immune systems are ready for huge numbers of antigens.
我們的身體和免疫系統已經做好了應對大量抗原的準備。
為什麼我們有不同的血型？(Why Do We Have Different Blood Types?)
- 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.
你的紅血球細胞天生就含有數百萬的抗原，而你的免疫系統不會對它們起反應，然後這些在你紅血球裡的抗原就決定了你的血型。
鏡像細菌是什麼？為何科學家認為它可能顛覆人類生存基礎 (Mirror Bacteria Could Destroy All Life As We Know It)
- Heterochiral components antigens are useful in drugs because the body can't break them down as easily.
異手性成分的抗原在藥物中很有用，因為身體不易分解它們。
你是哪種血型？ 一起來看看血型是如何保護我們！(How Your Blood Type Protects and Hurts You)
- 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。
