1题目研究人员培育了一种称为“裸鼠”的实验动物,这种鼠缺少胸腺,其免疫功能表现为( )A.体内淋巴细胞的种类减少B.体液免疫功能维持正常C.进入体内的细菌仍能被裂解D.机体仍能产生浆细胞答案ACD2质疑蒋世禄既然B细胞的分化需要T细胞分泌的淋巴因子信号,那么缺少胸腺的老鼠没有了T细胞怎么会有浆细胞产生?3讨论王学宏[河南省西华县第一高级中学(466600)]根据产生抗体时是否需要T细胞的参与,可将抗原
1 Subject Researchers have developed an experimental animal called “nude mice” lacking the thymus and showing immune function (A). The type of lymphocytes in the body is reduced B. The humoral immune function remains normal. Enter the body of bacteria can still be lysed D. The body can still produce plasma cells Answer ACD2 questioned Jiang Shilu Since the differentiation of B cells need T cells to secrete lymphokine signaling, then the lack of thymus mice without T cells how the plasma cells have? 3 Discussion Wang Xuehong [Xihua County, Henan Province, the first high school (466600)] according to the need for antibody production of T cells involved, the antigen
