CD34 was primarily regarded as hemopoietic stem cell antigen, but at present it was the most sensitive vessel marker.

CD 34原为造血干细胞抗原，现被认为是最敏感的血管标记物。

It is assumed that the reason resulting in such change is either t cell maturation of the down regulation of t cell antigen receptors.

推测造成这种T细胞亚群变化的原因可能与T细胞的发育成熟及T细胞本身的调节有关。

They might ingest extracellular antigen, presented pieces of it on their cell surface in the context of MHC-2.

它们可以吞噬胞外抗原,根据细胞表面的,主要组织相容性抗原-2

Yeast cells were grown in large numbers with this plasmid inside, they expressed the plasmid and so you made Hepatitis B surface antigen not in people but in cell culture where it was not normally formed.

体内携带这种质粒的酵母细胞大量增殖,它们表达质粒,因此,乙型肝炎表面抗原不是在人体内,而是在细胞培养环境下,以非正常方式形成的

But this antigen presenting cell is more likely a professional antigen presenting cell, or a subset of cells of your immune system that are specialized in ingesting foreign particles and displaying their contents to the rest of the immune system.

但这种抗原呈递细胞更加类似于,专职抗原呈递细胞,或者是体内免疫细胞中的一个亚群,专门从事吞噬异己物质,并告知免疫系统的其他细胞的工作

For a T cell to become active, it must receive signals from another part of the immune system called an antigen-presenting cell.

ECONOMIST: Breaching the body's defences

However, before the alarm can be sounded in this way, proteins on the surface of the antigen-presenting cell and the T cell must bind together in what is called a cellular handshake.
