一、脾脏的正常免疫功能脾脏能合成与释放多种淋巴因子并参与细胞的免疫反应。脾脏的B细胞受抗原刺激后能分化、增殖为浆细胞,从而合成IgA、IgG、IgM等免疫球蛋白,以发挥体液免疫功能。脾窦内皮细胞和脾索网状细胞具有活跃的吞噬功能、能有效的清除血流中的细菌、衰亡损伤的血细胞等异物。当机体受血中细菌的攻击而原 First, the normal immune function of the spleen can synthesize and release a variety of lymphokines and participate in cellular immune response. Spleen B cell differentiation by antigen stimulation, proliferation of plasma cells, and thus the synthesis of IgA, IgG, IgM and other immunoglobulins, in order to play humoral immune function. Splenic sinus endothelial cells and splenic reticulocytes with active phagocytic function, can effectively remove the bloodstream of bacteria, damaged blood cells and other foreign objects. When the body by the attack of bacteria in the blood
