如果一支动物被注射了异种或同种异系的另一支动物的细胞时,就会产生抗体应答反应。这种反应包括产生针对注入细胞的循环抗体。细胞含有大量的表面抗原,即能为反应动物的免疫系统识别为非自身的结构。每一种抗原能被针对其不同区域(即独立的抗 If one animal is injected with cells from another animal that is xenogenic or allogenic, an antibody response occurs. This reaction involves the production of circulating antibodies to the cells. Cells contain a large number of surface antigens, which can recognize the non-self-structure of the immune system of the reaction animal. Each antigen can be targeted at its different regions (ie, independent antigens
