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。

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

辅助性T细胞只有抗原被装载MHC II类分子呈递时才能够识别。

They will present their reports, take some questions.

会呈递的报告 回答几个问题。

These surface proteins act kind of like a serving platter, presenting molecules from within the cell for the immune system to continually sample.

这些膜表面蛋白像一个上菜的盘子一样，呈递细胞内的分子供免疫系统持续采样。

Other monocytes differentiate into dendritic cells, the prototypical antigen presenting cell, which roam around in the lymph, blood, and tissue.

其单核细胞会分化成树突状细胞，是典型的抗原呈递细胞；会淋巴、血液和组织中游走。

This may be done by isolating a specific protein from a pathogen and presenting it as an antigen on its own.

这可以通过从病原体中分离出特定的蛋白质并将其作抗原呈递来完成。

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.

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

In the matter of the Commonwealth versus Catherine Hapstall and the consideration of whether enough evidence has been presented to proceed to trial, I have made my decision.

联邦政府诉凯瑟琳·哈普斯托一案中，考虑过呈递的证据是否足以进一步庭审后，我已经做出了裁决。

When a B cell binds to an antigen that's on the surface of a pathogen, it is capable of phagocytosis and antigen presentation - so technically, they're also antigen presenting cells as well.

当B细胞和病原体表面的抗原结合以后，就能够吞噬并呈递抗原；所以实际上，也是抗原呈递细胞。

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MHC分子上以向T细胞展示当正确的T细胞出现时，就会结合！

And when he came to the United States in September of last year, he met with Donald Trump in New York, and he presented this victory plan to him.

因此， 去年九月， 泽连斯基总统访美期间，纽约与唐纳德·特朗普会面，并向其呈递了这份胜利计划。

In the lymph nodes, dendritic cells continuously sample the lymph and present antigens that they come across to the B cells which are a type of lymphocyte that can make antibodies.

淋巴结，树突状细胞持续对淋巴取样，呈递逮到的抗原给B细胞；B细胞是一类制造抗体的淋巴细胞。

The dendritic cell, which is part of the innate immune system, bridges the innate and adaptive immune responses when it presents the antigen to the T cell - part of the adaptive immune system.

树突状细胞，作固有免疫系统的一部分；呈递抗原给T细胞时，将固有和适应性免疫反应连接了起来（是适应性免疫的一部分）。

Dendritic cells will then move through the lymph to the nearest lymph node and they'll perform antigen presentation which is where they present those amino acid chains - which are antigens - to T cells.

接着，树突状细胞会通过淋巴转移到最近的淋巴结进行抗原呈递，也就是把那些氨基酸链（即抗原）呈递给T细胞的地方。

A naive T cell can be activated or primed to allow it to turn into a mature T cell by any of the antigen presenting cells, but most often it's done by a dendritic cell.

一个初始T细胞可以被激活或活化，让能转变一个成熟T细胞；这可以通过任意抗原呈递细胞来实现，但通常是通过树突状细胞完成的。

Next up are the monocytes, macrophages, and dendritic cells, which are phagocytic cells - they gobble up pathogens, present antigens, and release cytokines - tiny molecules that help attract other immune cells to the area.

接着是单核细胞、巨噬细胞和树突状细胞，三者都是吞噬细胞；大口吃病原体，呈递抗原，并释放细胞因子（即帮助号召其免疫细胞救兵来到局部的微小分子）。

Unfiltered lymph fluid drains into a nearby lymph node where any pathogen or piece of pathogen is quickly detected by a dendritic cell - a type of antigen-presenting cell that serves up pieces of anything in destroys to other immune cells.

未经过滤的淋巴液注入邻近淋巴结，任何病原体或者的一部分被树突状细胞迅速发现；树突状细胞是一类抗原呈递细胞，将任何有侵袭性物质的碎片呈递给其免疫细胞。

B cells are designed to only react to foreign antigens, and if the dendritic cell presents something foreign, the B cell turns into a plasma cells and starting cranking out antibodies which then flow into the lymph and exit the lymph node.

B细胞仅仅用于对异体抗原起反应，并且如果树突状细胞呈递异体物质，B细胞就会转变浆细胞，开始制造抗体而抗体随淋巴流出淋巴结。
