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托盘样。

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

辅助性T细胞只有在抗原被装载在MHC II类子呈递时才能够识别它们。

They will present their reports, take some questions.

他们会呈递他们写报告 回答几个问题。

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

其他单核细胞会化成树突状细胞，是典型抗原呈递细胞；它们会在淋巴、血液和游走。

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

这些膜表面蛋白像个上菜盘子样，呈递细胞子供免疫系统持续采样。

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离出特定蛋白质并将其作为抗原呈递来完成。

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.

和其他抗原呈递细胞样，B细胞将会把抗原装载在称为MHC II类子MHC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.

在联邦政府诉凯瑟琳·哈普斯托案，考虑过呈递证据是否足以进步庭审后，我已经做出了裁决。

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.

在淋巴结，树突状细胞持续对淋巴取样，呈递逮到抗原给B细胞；B细胞是类制造抗体淋巴细胞。

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在MHC子上以向T细胞展示当正确T细胞出现时，它们就会结合！

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细胞和病原体表面抗原结合以后，它就能够吞噬并呈递抗原；所以实际上，它们也是抗原呈递细胞。

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；它们大口吃病原体，呈递抗原，并释放细胞因子（即帮助号召其他免疫细胞救兵来到局部微小子）。

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，作为固有免疫系统部；在呈递抗原给T细胞时，将固有和适应性免疫反应连接了起来（是适应性免疫部）。

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淋巴结进行抗原呈递，也就是它们把那些氨基酸链（即抗原）呈递给T细胞地方。

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.

个初始T细胞可以被激活或活化，让它能转变为个成熟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。

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.

未经过滤淋巴液注入邻近淋巴结，任何病原体或者它部被树突状细胞迅速发现；树突状细胞是类抗原呈递细胞，将任何有侵袭性物质碎片呈递给其他免疫细胞。

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细胞就会转变为浆细胞，开始制造抗体而抗体随淋巴流出淋巴结。
