B-cells differentiate into plasma cells, which are found in the medulla or center of the lymph node.

B分化为浆；浆存在于结的髓质（结的中心）。

Plasma cells release antibodies or immunoglobulins.

浆以分泌抗体，即免疫球蛋白。

Some of these activated B-cells mature directly into plasma cells and produce IgM antibodies.

其中一些被激活的B直接成分化为浆并产生IgM抗体。

A sixth type of B cell lymphoma is lymphoplasmacytic lymphoma, and this one's also an indolent lymphoma.

第六类B瘤：浆瘤，也是一种惰瘤。

This causes them to transform into plasma cells.

这导致它们转化为浆。

Plasma cells then secrete millions of antibodies.

然后浆分泌数百万种抗体。

When a T cell gets activated it helps the B cell mature into a plasma cell, and a plasma cell can secrete lots and lots of antibodies.

当T被激活时，它也会帮助B成为浆；浆会分泌大量的抗体。

Others run defense for you, like the gamma globulin antibodies that are released by plasma cells during an immune response, or fibrinogen proteins, which are vital to forming blood clots and stopping bleeding.

另一些则为你提供防御，比如免疫反应期间浆释放的丙种球蛋白抗体，或者对形成血凝块和止血至关重要的纤维蛋白原蛋白。

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仅仅用于对异体抗原起反应，并且如果树突状呈递异体物质，B就会转变为浆，开始制造抗体而抗体随流出结。
