摘要

抗疟药氯喹和羟氯喹已被广泛用于治疗类风湿关节炎症和原发性红斑狼疮。这些混合物导致临床和研究设施参数的进步,然而,它们开始时的温和活性将它们与糖皮质激素和非甾体缓解剂区分开来。氯喹和羟氯喹增加细胞内液泡内的pH值,调节溶酶体酸性水解酶对蛋白质的降解,内体大分子的聚集,高尔基机械组装中蛋白质的翻译后变化等过程。这表明,这些混合物的抗风湿病特性是由于它们在巨噬细胞和其他抗原引入细胞中阻碍“抗原准备”。酸性细胞质区室是抗原蛋白处理和多肽与MHC II类蛋白α链和β链收集所必需的。因此,抗疟药物减少了激活CD4+ T细胞所需的肽- mhc蛋白结构的排列,并导致对自身抗原肽的安全反应的下调。由于该系统与其他抗风湿药物不同,因此在混合药物治疗中,抗疟药物适合作为这些不同混合物的补充[1]。

Hydroxychloroquine And Dexamethasone Are Both Possible For Treatment Of Covid-19
The antimalarial operators chloroquine and hydroxychloroquine have been utilized generally for the treatment of rheumatoid joint inflammation and fundamental lupus erythematosus. These mixes lead to progress of clinical and research facility parameters, however their moderate beginning of activity recognizes them from glucocorticoids and nonsteroidal mitigating operators. Chloroquine and hydroxychloroquine increment pH inside intracellular vacuoles and adjust procedures, for example, protein corruption by acidic hydrolases in the lysosome, get together of macromolecules in the endosomes, and posttranslation change of proteins in the Golgi mechanical assembly. It is suggested that the antirheumatic properties of these mixes results from their obstruction with "antigen preparing" in macrophages and other antigen-introducing cells. Acidic cytoplasmic compartments are required for the antigenic protein to be processed and for the peptides to collect with the alpha and beta chains of MHC class II proteins. Thus, antimalarials reduce the arrangement of peptide-MHC protein edifices required to animate CD4+ T cells and result in down-guideline of the safe reaction against autoantigenic peptides. Since this system varies from other antirheumatic drugs, antimalarials are appropriate to supplement these different mixes in blend medicate treatment[1].
