1·Antigen processing by macrophages precedes recognition of an antigen by lymphocytes.

抗原被巨噬细胞加工表示该抗原将被淋巴细胞识别。

2·The production of t cell epitopes depends on the antigen processing and presentation pathway.

而T细胞表位的产生依赖于抗原加工提呈过程。

3·Therefore, in the process of producting T cell epitope, the antigen processing and presentation pathway plays a key role.

因此，抗原的加工提呈过程对T细胞表位的产生起到决定性作用。

4·Objective To investigate the association between transporter associated with antigen processing(TAP) gene polymorphism and hepatocellular carcinoma(HCC).

目的探讨抗原处理相关转运蛋白（TAP）基因多态性与原发性肝细胞癌发生的相关性。
