免疫系统由大量不同类型的细胞和蛋白质组成，其功能是区分正常和异常细胞成分以及“自身”和“非自身”。举个例子，当一根刺卡在体内时，免疫细胞能够将刺识别为异物（即“非自身”）并攻击它。对于细菌、病毒或其他可以侵入我们身体的生物体来说也是如此。自我和非自我之间更微妙的区别发生在免疫系统对癌细胞的识别中。癌细胞之所以被识别并受到攻击，是因为它们不同于它们产生的正常“自我”。
The immune system consists of a large number of different types of cells and proteins that function to distinguish between normal and abnormal cellular components and between 'self' and 'non-self'. As an example, when a thorn gets stuck in the body, the immune cells are able to recognized the thorn as a foreign object (i.e. 'non-self') and attack it. The same is true for bacteria, viruses or other organisms that can invade our bodies. A more subtle distinction between self and non-self occurs in the recognition of cancer cells by the forces of the immune system. The cancer cells are recognized and attacked because they differ from the normal 'self' from which they arose.
