免疫JAV程序。在免疫反应过程中，大量的抗体的产生降低了抗原对免疫细胞的刺激，从而抑制抗体的分化和增殖，同时产生的抗体之间也存在着相互刺激和抑制的关系，这种抗原与抗体、抗体与抗体之间的相互制约关系使抗体免疫反应维持一定的强度，保证机体的免疫平衡。 -In the immune reaction process, a large number of antibodies produce reduces the antigen on the immune cell stimulation, thus inhibiting antibody differentiation and proliferation, and at the same time produce antibodies also exist between mutual stimulation and inhibition relationship, this kind of antigen and antibody, antibody and antibody and mutual restriction relationship between antibody immune response to maintain a certain strength, to ensure that the body s immune balance.
