白细胞介素-12(IL-12)是一种促炎和免疫调节细胞因子,通过诱导产生干扰素-γ和其他细胞因子在先天性和获得性免疫中起关键作用。IL-12被证明可以阻断紫外线诱导的免疫抑制,这在癌症免疫监视、皮肤过敏和炎症中很重要。为了表征IL-12在表皮中的分子效应,我们使用大的DNA微阵列,并定义了用IL-12处理后1小时、4小时、24小时和48小时的人表皮角质形成细胞以及用IL-12和UV光处理的细胞中的转录变化。在角质形成细胞中,IL-12激活STAT 3和STAT 4;令人惊讶的是,尽管激活了这些转录因子,IL-12的转录作用并没有上升到高于背景水平。然而,用IL-12预处理角质形成细胞强烈调节UV的转录作用。用IL-12预处理增强了UV介导的20个基因的调节,并拮抗了263个基因的调节。IL-12增强UV诱导的细胞因子的产生。IL-12拮抗细胞骨架、连接、代谢、线粒体和细胞外基质蛋白的抑制,同时拮抗某些信号蛋白和RNA加工酶的诱导。我们的结论是,在表皮,IL-12干扰紫外线照射的转录效应的特定子集。
Interleukin-12 (IL-12) is a proinflammatory and immunomodulatory cytokine that plays a critical role it in innate and adaptive immunity by inducing production of interferon-γ and other cytokines. IL-12 was shown to block the ultraviolet light-induced immunosuppression, important in cancer immunosurveillance, cutaneous allergies and inflammation. To characterize the molecular effects of IL-12 in epidermis we used large DNA microarrays and defined the transcriptional changes in human epidermal keratinocytes 1h, 4h, 24h, and 48h after treatment with IL-12, as well as in cells treated with both IL-12 and UV light. In keratinocytes, IL-12 activates STAT3 and STAT4; surprisingly, despite activating these transcription factors, the transcriptional effects of IL-12 did not rise above background levels. However, pre-treatment of keratinocytes with IL-12 strongly modulated the transcriptional effects of UV. Pre-treatment with IL-12 enhanced the UV-mediated regulation of 20 and antagonized the regulation of 263 genes. IL-12 enhanced the induction of cytokines by UV. IL-12 antagonized the suppression of cytoskeletal, junctional, metabolic, mitochondrial, and extracellular matrix proteins, while antagonizing the induction of certain signaling proteins and RNA processing enzymes. We conclude that in the epidermis, IL-12 interferes with a specific subset of transcriptional effects of UV irradiation.
