最近外电报道:英国国立医学研究所基因结构研究室的一研究小组对小鼠的研究结果表明,由于机体本身的细胞被所谓“主要组织相容性复合体(MHC)基因“产生的”标记蛋白”所标记,因而机体能识别其本身的细胞。但是,当这些细胞癌变时,它们丧失这种特征性标志,因此逃避了机体天然防御系统的检测。 Frank Grosveld等发现,如果将MHC基因重新引入肿瘤细胞,这种特征性的标记蛋白就再次出现在瘤细胞表面,小鼠的防御系统能识别它们,但因为这些细胞并非完全正常的 According to a recent foreign report, a study conducted by a team of researchers from the Institute of Genome Structure of the National Institute of Health in the United Kingdom showed that due to the fact that cells of the body itself are labeled by so-called “major histocompatibility complex (MHC) genes” "Labeled, so the body can recognize its own cells. However, when these cells become cancerous, they lose this characteristic marker and thus evade detection of the body’s natural defense system. Frank Grosveld et al. Found that if the MHC gene is reintroduced into tumor cells, this characteristic marker protein reappears on the surface of tumor cells and the mouse defense system recognizes them, but because these cells are not completely normal
