As the virus destroys and impairs the function of immune cells, infected individuals gradually become immunodeficient.
随着该病毒破坏和损害免疫细胞功能，感染者免疫系统逐渐出现缺陷。

Subcutaneous injection of colon cancer CD133 + cells readily reproduced the original tumour in immunodeficient mice, whereas CD133-cells did not form tumours.
将此细胞接种于免疫缺陷小鼠皮下，很易产生原始瘤。而CD 133 -细胞不能形成肿瘤。

We developed an immunodeficient mouse model to test the tumorigenic potential of different populations of cancer cells derived from primary, unmanipulated human HNSCC samples.
