人體免疫系統大揭密！ (The Immune System)
- is called antigen. And so basically what a macrophage will do is it will notice that
任何的入侵物被稱為"抗原"。巨噬細胞會找到不是我們身體的一部分
- response is more like the spies. And so basically here's an antigen again. An antigen is going
后天免疫系统就像是間諜。這是個抗原。
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)
- 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。

血液，第一部 - 真愛急診室：人體解剖學速成班 #29 (Blood, Part 1 - True Blood: Crash Course A&P #29)
- So if you don't have a particular antigen on your blood cells, say the type B, then you do have antibodies that are going to label those B antigens for attack, should they enter your space.
這些不同的血型都能夠達到相同的目的，只是你的免疫系統有些
- So if you don’t have a particular antigen on your blood cells -- say the type B -- then
所以你的血球上若沒有特定一種抗原 -- 假設是B型好了 -- 那麼
器官也有血型？這竟是個大麻煩！ (Organs Have Blood Types and It's a Problem)
- The type of antigen is dictated by genetics, and people generally have antibodies against the types their cells don't express.
抗原的類型由基因決定，而且人們通常對他們細胞不表現的類型有抗體。
- In this case, the doctors used a specific enzyme to pop off the type A antigen on the kidney cells before doing the transplant,
在這個案例中，醫生們使用了一種特定的酵素，在進行移植前，將腎臟細胞上的 A 型抗原移除，讓移植的器官在一段時間內基本上變成 O 型。
為什麼不應該強制退燒 (Why You Shouldn’t Fight A Fever)
- 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。
你的免疫系統：天生的殺手！ - Crash Course 生物學 #32 (Your Immune System: Natural Born Killer - Crash Course Biology #32)
- An antigen is anything that causes your immune system to idea a pathogen and then create an antibody against it.
抗原是任何會讓你的免疫系統辨識病原體，然後產生抗體的東西。
- After the deed has been done, it has the ability to shred up the proteins from an invader and put a bit of that antigen on its membrane surface.
完成任務後，它有能力分解入侵者的蛋白質，並將一部分抗原放在其細胞膜表面。
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
