释 义 n. 一个新的免疫检查点
例 句 Those CD94+ tumor-infiltrating lymphocytes mostly corresponded to CD8+ αβ T cells, and to a lesser extent to NK cells, and mainly co-expressed a functional inhibitory NKG2A chain. 那些CD94 +肿瘤浸润淋巴细胞主要与CD8 +αβT细胞、NK细胞（在较小程度上），主要共表达一个功能抑制NKG2A链。

In contrast to classical HLA molecules which are frequently lost, HLA-E protein levels are generally increased in cancer when compared to their healthy counterparts, as described in lung, kidney, pancreas, stomach, colon, head and neck, liver, melanoma, prostate, and rectal tumor tissues. Exact mechanisms influencing this differential expression remain to be determined. However, anti-tumor immunity and IFN-γ, in particular, promote HLA-E expression at the tumor cell surface.
