Immunotherapy comprises administration of an alkaloid at a dose sufficient to induce IL-2 production in dendritic cells in a patient. The alkaloid induces the production of IL-2 in dendritic cells. The alkaloids need not be naturally occurring, and may be synthetic analogues or derivatives of naturally occurring counterparts. Such analogues or derivatives are preferably pharmaceutically acceptable analogues, salts, isomers or derivatives as herein defined. However, preferred alkaloids are phytochemicals. Such phytochemicals may be isolated from natural sources or synthesised in vitro. Particularly preferred are alkaloids is selected from piperidine alkaloids; pyrrolin alkaloids; pyrrolidine alkaloids; pyrolizidine alkaloids: indolizidine alkaloids and nortropane alkaloids.
免疫疗法包括在患者体内以足够剂量给予一种生物碱,以诱导树突状细胞产生IL-2。这种生物碱会引起树突状细胞产生IL-2。这些生物碱不一定是天然存在的,也可以是天然存在的衍生物或合成类似物。这些类似物或衍生物最好是药学上可接受的类似物、盐、异构体或衍生物,如本文所定义。然而,最好的生物碱是植物化学物质。这些植物化学物质可以从天然来源中分离出来,也可以在体外合成。特别优选的生物碱包括吡啶生物碱、吡咯烷生物碱、吡咯烷生物碱、吡咯菊烷生物碱、吲哚菊烷生物碱和诺滕烷生物碱。
