閱讀筆記:免疫抑制劑於實體器官移植與骨髓移植
免疫抑制劑於實體器官移植與骨髓移植 簡介 回顧目前於實體器官移植和骨髓移植中使用的主要免疫抑制劑種類、其作用機制、生理效應以及潛在的副作用。免疫抑制的進展顯著提升了移植的成功率,透過針對特定的免疫訊號傳遞路徑和活化機制,選擇性地抑制免疫反應,從而降低急性及慢性排斥的發生率,並減輕骨髓移植後可能發生的移植物抗宿主疾病(GVHD)。 正如文件中所述:「The success of solid organ and bone marrow transplantation (BMT) has correlated with improvements in selective immunosuppression. Immunosuppression decreases both the incidence of acute and chronic organ graft and bone marrow rejection, and a potentially life threatening complication of BMT known as graft-vs-host disease (GVHD). Selective immunosuppression targets specific pathways of immune signaling and activation, and minimizes the incidence of deleterious side effects.」 免疫抑制劑種類與作用機制 以下將詳細介紹各類免疫抑制劑的作用機制、生理效應和副作用,並引用原文中的描述。 (1) 類固醇 (Corticosteroids) 生化機制: 「Affect NF-AT mediated pathway of signal transduction, which results in ultimate blockade of IL-1 and IL-6 production in macrophages at the earliest stage of immune response.」類固醇影響 NF-AT 介導的訊號傳導路徑,最終阻斷巨噬細胞在免疫反應早期產生 IL-1 和 IL-6。 生理效應: 「Inhibits leukocyte...
