When it comes to medical tests that diagnose COVID, there are two main options, the antigen or rapid test and the polymerase test.

现存主要有两种检测新冠病毒的医学测试方法，一种是原或快速检测，另一种是聚合酶链式检测即核酸检测。

Give a little piece of the virus, also known as antigen, to someone not enough to make them sick and their body will be taught to make antibodies to it.

那就是，把一小块病毒，也称为原，输入人体中，要确保病毒不足以使这些人生病，然后他们的身体就会产生体。

The thymus is involved in the development of T cells - making sure that any T cells that react to self-antigens, antigens that are normally found in the body, are promptly destroyed.

胸腺与T细胞的育有关，确保任何对自体原（正常情况下机体中的原）起反应的T细胞迅速被破坏。

It's a live attenuated vaccine, and we're engineering it to express SARS-CoV-2 antigens, which should trigger the production of protective antibodies by the immune system.

这是一种减毒活疫苗，我们通过生物工程达 SARS-CoV-2 原，以此来触免疫系统产生保体。

The body is then able to produce large numbers of corresponding antibodies within a short time, so the invading antigens are quickly wiped out without the person suffering any harm from the disease.

这样，人体就能在短时间内产生大量相应的体，因此入侵的原很快被清除，而患者不会受到疾病的任何伤害。

Cheap and rapid antigen testing can identify and prevent every cluster of COVID-19.

便宜且快速的原检测可以识别和预防每一个新冠肺炎人群。

It's looking for the actual antigen, the actual RNA of the virus.

鼻腔拭子检测寻找真正的原，也就是病毒的真正RNA。

MHC is like the serving platter that antigens are presented to the immune cells.

MHC就像是原呈递给免疫细胞的托盘一样。

But, although they present antigens, they're also a form of antigen themselves.

但尽管HLA提呈原，们自身也是原。

Unfortunately, matching donors and recipients is a bit more complicated due to additional antigen systems, particular the Rh factor, named after the Rhesus monkeys in which it was first isolated.

不幸的是，由于额外的原系统，将捐献者与接收者匹配稍微有点复杂。尤其是Rh因子，这个因子是以恒河猴第一次被隔离之后的地方命名的。

Blood Group Facts There are eight different common blood types, which are determined by the presence or absence of certain antigens, which are substances that can trigger an immune response if they are foreign to the human body.

血型信息常见的血型有八种，们是由某些原的存在或缺失决定的，这些原是一种物质，如果们是人体的外来物质，就可以触免疫反应。

One potential circulating antigen that's been identified is cationic bovine serum albumin, which is present in cow's milk and beef protein, and can escape the intestinal barrier, cause immune complex formation, and deposit in the GBM.

一种已现的潜在循环原是阳离子化牛血清白蛋白，存在牛奶和牛肉蛋白质中，并可逃离肠道屏障，导致免疫复合物形成，沉积在基底膜。

To be clear, these bacteria and viruses don't directly damage the myelin sheath, instead it's thought that they have antigens on their surface that looks similar to the lipid in the myelin sheath.

需要说明的是，这些细菌或病毒并不直接损伤髓鞘，相反，们的面原类似于髓鞘的脂质。

For example, if you have type B blood and you receive a blood transfusion of type A blood, your antibodies will work to destroy the A antigens.

例如，如果你是B型血，却输了A型血，你的体就会破坏A型血原。

Some researchers have found that increasing exposure to an antigen over time, usually in drops placed under the tongue, can desensitize the body from reacting.

一些研究人员现，随着时间的推移，接触原的次数增多（通常是在舌下滴入的液滴中），会使身体失去反应力。

Officials say hidden transmission sources in communities still exist and Beijing will use antigen testing as a supplementary measure to screen key risk groups and staff in key industries.

官方示，社区中面依然存在隐匿传染源，北京将把原检测作为一项补充措施，对重点风险人群和重点行业的工作人员进行筛查。

So you can imagine, just the variation in what we call antigens, different carbohydrates and proteins that–the genetic code is just really different between a pig and human.

你可以想象，人和猪之间存在原差异，碳水化合物、蛋白质也不同，遗传密码也是大相径庭。

All told, these findings suggest that nurse bees are indeed, via their royal jelly, passing antigens on to the queen for inoculation into her eggs.

综上所述，这些现明，看蜂确实通过蜂王浆将原传给蚁后，以便将其接种到卵中。

Although it's not always needed, diagnostic testing for RSV can be done by swabbing epithelial cells in the nasopharynx and looking for the presence of viral antigens.

可以通过擦拭鼻咽部上皮细胞，检查是否存在病毒原，但这一检查并不是人人都必要的。

Beijing Jiaotong University had asked test takers to monitor their health condition beginning on Monday and report nucleic acid test results or antigen test results before Tuesday.

北京交通大学要求考生从周一开始监测自己的健康状况，并在周二之前上报核酸检测结果或原检测结果。
