Abstract:
BACKGROUND:Cyclosporine A has shown its immunosuppressive effects and has been widely used in clinical organ transplantation.OBJECTIVE:To review the recent studies on the immunosuppressive mechanisms and the active pathway of cyclosporine A.RETRIEVAL STRATEGY:A compute-based online search of ScienceDirect Onsite,ProQuest,Springer and Ovid,based on the data from Peking University Medical Library,was undertaken for the English articles concerning with the immunosuppressive mechanism of cyclosporine A from January 1990 to December 2006,with the keywords of "cyclosporine A,mechanism/action,immunosuppression".Totally 68 articles were collected after the first trial,and the preliminary screening was conducted for the titles and abstracts.Inclusion criteria:articles related with the immunosuppressive mechanisms of cyclosporine A.Repetitive studies were excluded.Fifty accorded with the inclusive criteria,and 46 of them regarding tracheal transplantation were selected for the full-texts as the references.LITERATURE EVALUATION:Forty-six included articles included 6 ones about the clinical use and effects of cyclosporine A,and 40 involving the related studies on the molecular mechanisms of cyclosporine A.DATA SYNTHESIS:The review of literatures indicates that,the immunosuppressive mechanisms of cyclosporine A consist of:① the calcineurin/nuclear factor of activated T-cells pathway,②the activation of JNK and P38 signaling pathways,③other effects.CONCLUSION:Cyclosporine A selectively regulates the function of peripheral blood lymphocytes subgroup,blocks the activation of cytotoxic T-cells,and possibly inhibits the formation or reaction of memory T-cells.But it doesn't affect activation and proliferation of suppressive T-cells,or expression of interleukin-2 receptors,which may induce selective immunosuppression.
