恶性肿瘤的免疫疗法是肿瘤免疫学中一个很活跃的领域。近年来“免疫”核糖核酸颇引人重视。从抗元致敏的淋巴细胞或巨噬细胞提取核糖核酸,可将特异的免疫性转移给正常的淋巴细胞,使之致敏。这种能传递免疫信息的RNA称为“免疫”RNA。它与转移因子不同,分子量较大,既可转移细胞免疫,也可转移体液免疫。 Immunotherapy of malignant tumors is a very active field in tumor immunology. In recent years, “immunization” RNA has attracted considerable attention. Extraction of ribonucleic acid from anti-primed lymphocytes or macrophages can transfer specific immunity to normal lymphocytes for sensitization. This kind of RNA that can transmit immune information is called “immunized” RNA. Unlike the transfer factor, it has a large molecular weight and can transfer both cellular and humoral immunity.
