广州医学院第一附属医院儿科主任、中年讲师吴梓梁在美国进修期间,首次在一个患神经母细胞瘤的病儿血液中,发现神经母细胞瘤的标记物——神经节甙脂GD_2。这一发现,将为神经母细胞肿瘤的早期诊断提供了有效手段,并证实了“肿瘤细胞的神经节甙脂可以释放到血液中去”的假说,释放到血液中的GD_2对肿瘤病人的细胞免疫力有抑制作用,在理论 First Affiliated Hospital of Guangzhou Medical College pediatric director, middle-aged lecturer Wu Ziliang during the United States during the study, for the first time in a patient suffering from neuroblastoma blood, found neuroblastoma marker - ganglioside GD_2. This discovery will provide an effective means of early diagnosis of neuroblastoma and confirm the hypothesis that “the tumor cells of ganglioside can be released into the bloodstream”. The release of GD2 to the blood in the patient’s cells Immune inhibition, in theory
