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

MHC就像是抗原呈递给免疫细胞的托盘一样。

A woman's nose is particularly attuned to MHC molecules, which are used to fight disease.

女性的鼻子对一种名为MHC分子的化学物质尤为敏感。这种物质是用来对抗疾病的。

Helper T cells can only see their antigen if it is presented on an MHC II molecule.

辅助性T细胞只有在抗原被装载在MHC II类分子呈递时才能够识别它们。

Based on studying people with autoimmune hepatitis, they often have HLA-DR3 and -DR4, which are both MHC class II surface receptors.

基于对自免肝病人的研究，他们（的体细胞表面）常常含有HLA-DR3和HLA-DR4，两者都是MHC-II类分子。

He says there are some links between the 11 genetic markers, called MHC type, and attraction.

他说，这 11 种遗传标记（称为 MHC 类型）与吸引力之间存在一些联系。

Like other antigen presenting cells, the B cell will load the antigen onto an MHC molecule called MHC II, and display it to T cells.

和其他抗原呈递细胞一样，B细胞将会把抗原装载在称为MHC II类分子的MHC分子上然后展示给T细胞。

Most individuals with ankylosing spondylitis have the gene HLA-B27, which is a gene that encodes for a specific type of MHC class I molecule.

许多强直性脊柱炎患者都携带HLA-B27基因，该基因能编码一种特定的MHC Ⅰ类分子。

The immune system uses Major Histocompatibility Complex or MHC molecules to bind to the peptides and carry them to the cell surface.

免疫系统使用主要组织相容性复合体或 MHC 分子与肽结合并将它们带到细胞表面。

The main difference is that B cells don't need antigen to be presented to them on an MHC molecule, they can simply bind an antigen directly.

主要的不同之处在于：B细胞不需要抗原结合在MHC分子“银盘”上呈献给它们，而可以直接与抗原结合。

Sequencing can also reveal what what the MHC molecules will look like and, together with the mutant protein sequences, this can predict which neoantigens cells will display.

测序还可以揭示 MHC 分子会是什么样子，并且与突变蛋白序列一起， 这可以预测哪些新抗原细胞会显示。

So the antigen presenting cell will load the antigen onto an MHC molecule and display it to T cells - and when the right T cell comes along - it binds!

所以抗原呈递细胞会把抗原装载在MHC分子上以向T细胞展示当正确的T细胞出现时，它们就会结合！

But this is only half the story because even when neoantigen MHC complexes are produced, the immune system might still miss them and fail to respond to the threat.

但这只是故事的一半，因为即使产生了新抗原 MHC 复合物，免疫系统仍可能错过它们并且无法应对威胁。

However, T cells can only see their antigen if it is presented to them on a silver platter - and on a molecular level that platter is the Major Histocompatibility complex or MHC for short.

然而，T细胞只有在抗原被放入“银盘”中献上时才会瞥到它们；在分子维度上，这个“银盘”即主要相容性复合体，简写为MHC。

To help with this, most cells in the body have a set of proteins that combine together to form something called a major histocompatibility complex, or MHC, class I molecule that sits on the surface of their cell membrane.

全身多数细胞都有一组蛋白来协助这个过程；这些蛋白结合在一起能形成主要组织相容性复合物（MHC），而MHC Ⅰ类分子就位于细胞膜表面。

Around this point in the infection, immature dendritic cells digest the pathogens and move from the lung tissue over to a nearby lymph node where they present the processed antigen on an MHC II protein to a naive T cell.

在感染进行到这一阶段时，未成熟的树突状细胞会消化病原体，然后从肺组织迁移到临近的淋巴结；在这里它们处理抗原至MHC II类分子，并呈递给初始T细胞。
