细胞因子是调节机体细胞免疫的重要物质。已有实验表明 ,γ 干扰素可明显提高机体抗肿瘤、抗感染的能力。随着分子生物学及分子遗传学等基础学科的发展 ,疾病的基因治疗已成为当今研究的热点。构建可供基因转染的真核细胞表达载体 ,是进行基因转染研究的基础 ,具有重要的实用价 Cytokines are important substances that regulate cellular immunity in the body. Experiments have shown that interferon gamma can significantly improve the body’s anti-tumor, anti-infective ability. With the development of basic disciplines such as molecular biology and molecular genetics, the gene therapy of diseases has become a hot spot in today’s research. Construction of eukaryotic expression vectors for gene transfection is the basis for gene transfection research and has important practical value
