    • In order to provide a gene expression enhancer for enhancing expression of FoxP3 gene in a cell; a cell differentiation inducer for inducing differentiation of a cell into a regulatory T cell; an immunosuppressor for suppressing immunity and an agent for treating hyperimmune diseases based on the abovementioned actions; an inhibitor of enhancement of gene expression for inhibiting enhancement of expression of FoxP3 gene in a cell; an inhibitor of induction of cell differentiation for inhibiting induction of differentiation of a cell into a regulatory T cell; a reducer of immunosuppression for reducing immunosuppression, a stimulator of tumor immunity and an antitumor agent based on the abovementioned actions; and the like, for example, an agent containing at least one of a cell expressing Snail protein, MCP1 protein, FSTL1 protein, membrane IL-13Ra2 protein or secretory IL-13Ra2 protein, or MCP1 protein, FSTL1 protein or secretory IL-13Ra2 protein, is used as a gene expression enhancer for FoxP3, an inducer of regulatory T cell differentiation, an immunosuppressor or an agent for treating hyperimmune diseases; and an agent containing an anti-MCP1 antibody, an anti-FSTL1 antibody or an anti-IL-13Ra2 antibody is used as an inhibitor of enhancement of FoxP3 gene expression, a reducer of immunosuppression, a stimulator of tumor immunity, an antitumor agent, or the like.
    • 为了提供用于增强细胞中FoxP3基因表达的基因表达增强子; 用于诱导细胞分化成调节性T细胞的细胞分化诱导物; 用于抑制免疫的免疫抑制剂和基于上述作用的用于治疗超免疫疾病的药剂; 用于抑制细胞中FoxP3基因表达增强的基因表达增强抑制剂; 用于抑制诱导细胞分化成调节性T细胞的细胞分化诱导抑制剂; 基于上述作用的减少免疫抑制的减少剂,免疫抑制的刺激剂和抗肿瘤剂; 例如含有表达Snail蛋白,MCP1蛋白,FSTL1蛋白,膜IL-13Ra2蛋白或分泌型IL-13Ra2蛋白的细胞或MCP1蛋白,FSTL1蛋白或分泌型IL-13Ra2蛋白中的至少一种的药剂 用作FoxP3的基因表达增强子,FoxP3是调节性T细胞分化的诱导剂,免疫抑制剂或治疗超免疫疾病的药剂; 使用含有抗MCP1抗体,抗FSTL1抗体或抗IL-13Ra2抗体的药剂作为FoxP3基因表达增强抑制剂,免疫抑制剂的减少剂,肿瘤免疫刺激剂,抗肿瘤剂, 或类似物。
