- On the other hand, the exposed H antigen on O blood cells can be a point of entry for certain pathogens, which is why O individuals are more vulnerable to severe cases of cholera and norovirus.
另一方面，O型血球上暴露的H抗原可能成為某些病原體的入侵點，這也是為什麼O型個體更容易罹患嚴重霍亂和諾羅病毒的原因。
- The A antigen has been linked to a stronger immune response against certain bacterial infections, particularly those that spread in dense agricultural communities where hygiene challenges were greater.
A抗原已被證實能對某些細菌感染產生更強的免疫反應，特別是在衛生條件較差的密集農業社群中傳播的感染。

- In the study, researchers injected mice with an antigen and then monitored the activation of a type of lymphocyte called CD8+ cytotoxic T cells, which are capable of killing cells infected with viruses and even cancer cells.
在這研究中，研究人員將抗原注射到老鼠身上，然後觀察其之後淋巴球的活化，也就是所謂的细胞毒性T細胞，能消滅受到病毒感染的細胞，甚至是殺死癌細胞。
為什麼我們有不同的血型？(Why Do We Have Different Blood Types?)
- These antibodies recognize the foreign object, which we call an antigen and attack it.
這些抗體會認出外來體並攻擊它，而我們稱這些外來體為抗原。
- The antibody then attaches itself to the antigen similar to a locking key, which is what keeps you from getting sick.
抗體接著就會把自己附著在抗原的上，像上鎖的鑰匙般，這就是為什麼你能免於生病的原因。

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)
- The blood type you have is the result of a specific kind of antigen—in this case, a type of sugar—on the surface of your red blood cells.
之所以血型會有區別是在於紅血球表面的一種特定的抗原，而在這種情況下這些抗原是某種醣類。
- If you have the A antigen, you're type A; if you have the B antigen, you're B.
如果紅血球表面有 A 型抗原，你就是 A 型血，而如果你有 B 型抗原，你就是 B 型。
為什麼我們會有不同血型 (Why Do We Have Different Blood Types?)
- will attack anything with an A or B antigen. But any other blood type can accept type O blood
會攻擊任何有 A 或 B 抗原的細胞。但其他血型的人都能接受 O 型血
- Type A means cells have the A antigen so they can’t receive type B blood,
A 型表示細胞有 A 抗原，所以他們不能接受 B 型血，而 B 型表示
