沙利度胺(塔尔)是一种有效的免疫调节剂。由于它们在控制免疫中的核心作用,我们研究了塔尔对单核细胞衍生的树突状细胞(Mo-DC)的影响。从单核细胞培养开始加入10 μg/ml或20 μg/ml塔尔与粒细胞巨噬细胞集落刺激因子和白细胞介素(IL)-4,不会阻断Mo-DC分化。此外,单独的塔尔不能诱导Mo-DC成熟。然而,塔尔发挥调制的Mo-DC功能特性。在10 μg/ml时,塔尔几乎没有改变DC的同种异体刺激能力,而20 μg/ml的剂量上调了这种能力(P=.05),并在10和20 μg/ml之间以剂量依赖性方式增加了IL-12 p70的产生(P=.001)。用10 μg/ml塔尔产生的Mo-DC是T辅助细胞1型(Th 1)应答的不良刺激物(P=.01),但20 μg/ml能够加强Th 1应答(P=.03)。此外,响应于成熟诱导刺激物CD 40 L,塔尔诱导IL-10产生的显著减少。类似地,当Mo-DC暴露于10 μg/ml塔尔时,肿瘤坏死因子α的产生显著降低,并且20 μg/ml的剂量未诱导任何显著变化。塔尔体外对IL-12 p70分泌的影响和Th 1应答的增强可能有助于塔尔的抗肿瘤作用。因此,DC似乎是塔尔的免疫调节能力的潜在靶点,定义了该药物的新作用机制。
Thalidomide (Thal) was shown to be a potent immunomodulating agent. Because of their central role in controlling immunity, we investigated the effects of Thal on monocyte‐derived dendritic cells (Mo‐DC). The addition of 10 μg/ml or 20 μg/ml Thal from the beginning of monocyte culture with granulocyte macrophage‐colony stimulating factor and interleukin (IL)‐4 did not block Mo‐DC differentiation. Moreover, Thal alone could not induce Mo‐DC maturation. However, Thal exerted a modulation of Mo‐DC functional properties. At 10 μg/ml, Thal modified the allostimulatory capacity of DC little, whereas a dose of 20 μg/ml up‐regulated this capacity (P=.05) and increased IL‐12p70 production in a dose‐dependent manner between 10 and 20 μg/ml (P=.001). Mo‐DC generated with 10 μg/ml Thal were poor stimulators of T helper cell type 1 (Th1) responses (P=.01), but 20 μg/ml was able to strengthen Th1 responses (P=.03). Also, Thal induced a significant reduction of IL‐10 production in response to the maturation‐inducing stimulus CD40L. Similarly, tumor necrosis factor α production was significantly decreased when Mo‐DC were exposed to 10 μg/ml Thal, and a dose of 20 μg/ml did not induce any significant changes. The effects of Thal in vitro on the secretion of IL‐12p70 and strengthening of Th1 responses might contribute to the antitumor effects of Thal. Thus, DC appear to be potential targets for the immunomodulatory capacity of Thal, defining a new mechanism of action of this drug.
