核酸疫苗又称DNA疫苗,是指将编码某种目的抗原蛋白的外源基因插入真核细胞表达质粒,直接导入动物体细胞内,并通过宿主细胞的表达系统合成抗原蛋白,诱导宿主产生对该抗原蛋白的免疫应答,从而达到预防和治疗疾病的目的。核酸疫苗不仅能刺激机体产生特异性的体液免疫,还能诱导产生 Nucleic acid vaccine, also known as DNA vaccine, refers to the foreign gene encoding a certain antigen of interest inserted into the eukaryotic expression plasmid, directly into the body cells of animals and host cells through the expression of the synthesis of antigen protein synthesis system to induce the host to produce the Antigenic protein immune response, so as to achieve the purpose of prevention and treatment of diseases. Nucleic acid vaccine can not only stimulate the body to produce specific humoral immunity, but also induce the production
