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

MHC就像呈递给免疫细胞的盘样。

They will present their reports, take some questions.

他们会呈递他们写的报告 回答几个问题。

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

辅助性T细胞只有在被装载在MHC II类分子呈递时才能够识别它们。

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

其他单核细胞会分化成树突状细胞，典型的呈递细胞；它们会在淋巴、血液和组织中游走。

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的盘子样，呈递细胞内的分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.

这可以通过从病体中分离出特定的蛋白质并将其作为呈递来完成。

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.

和其他呈递细胞样，B细胞将会把装载在称为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.

在联邦政府诉凯瑟琳·哈案中，考虑过呈递的证据否足以进步庭审后，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，呈递逮到的给B细胞；B细胞类制造体的淋巴细胞。

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!

所以呈递细胞会把装载在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！

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细胞和病体表面的结合以后，它就能够吞噬并呈递；所以实际上，它们也呈递细胞。

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.

接着单核细胞、巨噬细胞和树突状细胞，三者都吞噬细胞；它们大口吃病体，呈递，并释放细胞因子（即帮助号召其他免疫细胞救兵来到局部的微小分子）。

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，作为固有免疫系统的部分；在呈递给T细胞时，将固有和适应性免疫反应连接了起来（适应性免疫的部分）。

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呈递，也就它们把那些氨基酸链（即）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.

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；这可以通过任意呈递细胞来实现，但通常通过树突状细胞完成的。

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，任何病体或者它的部分被树突状细胞迅速发现；树突状细胞类呈递细胞，将任何有侵袭性物质的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，开始制造体而体随淋巴流出淋巴结。
