经肿瘤细胞免疫的纯系动物,常能耐受致瘤量注射,从而引起学者们探索人类肿瘤是否存在抗原性。动物实验表明化学或病毒诱生肿瘤皆具有特异性抗原,该抗原称为肿瘤排斥相关抗原(TARA)。而由细胞免疫与体液免疫方法所检得的抗原则为肿瘤细胞表面抗原(TCSA)。将肿瘤细胞浸出液注于患者皮内,能出现特异性迟发型变态反应,因而推测人类 The pure animal immunized by tumor cells can often tolerate tumorigenic injections, causing scholars to explore the existence of antigenicity in human tumors. Animal experiments have shown that chemically or virally induced tumors all have specific antigens called the Tumor Rejection Associated Antigen (TARA). The antigen detected by cellular and humoral immunity methods was tumor cell surface antigen (TCSA). Injecting tumor cell leachate into the patient’s skin, a specific delayed-type hypersensitivity can occur, thus inferring humans
