类固醇用于自身免疫性疾病等表现免疫异常的疾病上,临床方面已得到肯定的评价。然而它对免疫系统的作用机制尚未充分阐明,目前正在继续探索。构成免疫系统的细胞有单核细胞、巨噬系统细胞、淋巴细胞(T 细胞、B 细胞、大颗粒淋巴细胞)、胸腺上皮细胞等。这些细胞构成脾脏、淋巴结、骨髓等器官或循环于血液、淋巴液中。类固醇对这些细胞、器官基本上起广泛抑制作用。 Steroids are used in autoimmune diseases and other manifestations of immune disorders, the clinical aspects have been affirmed. However, its mechanism of action on the immune system has not yet been fully elucidated and it is continuing to be explored. Mononuclear cells, macrophage system cells, lymphocytes (T cells, B cells, large granular lymphocytes), thymus epithelial cells and the like are included in the cells constituting the immune system. These cells form spleen, lymph nodes, bone marrow and other organs or circulate in blood and lymph. Steroids on these cells and organs basically play a broad inhibitory effect.
