摘要

目的为了研究抗IL-23A抗体利桑珠单抗对IL-36γ/IL-23A/IL-17A信号级联的影响,我们使用了一种新开发的由原代人类角质形成细胞、成纤维细胞和γδ-T细胞组成的三维皮肤模型。方法在这项体外研究中,我们开发了新的全厚三维皮肤模型,其中包含正常人表皮角质细胞(NHEK)、正常人真皮成纤维细胞(NHDF)以及对 IL-23A 有反应并能产生 IL-17A 的γδ-T 细胞。结果在初步的单层实验中,用 IL-23A 刺激γδ-T 细胞可促进 IL-17A 的表达,而利桑珠单抗治疗后可抑制 IL-17A 的表达。我们使用含有γδ-T细胞的三维皮肤模型发现,IL-36γ刺激不仅会显著增加IL-23A的表达,还会增加IL-17A的表达。结论我们的研究结果表明,阻断 IL-23A 对 IL-36γ/IL-23A 前馈环有抑制作用。我们新开发的三维皮肤模型含有对IL-23A有反应且能产生IL-17A的γδ-T细胞,可以对针对银屑病中IL-36γ/IL-23A/IL-17A信号级联的靶向疗法进行分子分析。

Understanding the impact of risankizumab on keratinocyte-derived IL-23A in a novel organotypic 3D skin model containing IL-23A responsive and IL-17A producing γδ-T-cells.

Purpose: To study the effects of the anti-IL-23A antibody risankizumab on the IL-36γ/IL-23A/IL-17A signalling cascade we used a newly developed 3D skin model consisting of primary human keratinocytes, fibroblasts and γδ-T-cells.

Methods: In this in vitro study we developed new full-thickness 3D skin models containing normal human epidermal keratinocytes (NHEK), normal human dermal fibroblasts (NHDF) and IL-23A responsive and IL-17A producing γδ-T-cells. The effects of IL-36γ stimulation with and without risankizumab treatment on IL-23A and IL-17A expression were examined at the RNA and protein levels.

Results: In preliminary monolayer experiments stimulation of γδ-T-cells with IL-23A promoted the IL-17A expression that was inhibited after risankizumab treatment. Using 3D skin models containing γδ-T-cells, we found that stimulation with IL-36γ significantly increased not only IL-23A but also IL-17A expression. These effects were inhibited by concomitant treatment with risankizumab.

Conclusions: Our results showed that blockade of IL-23A has inhibitory effects on the IL-36γ/IL-23A feedforward loop. Our newly developed 3D skin model containing IL-23A responsive and IL-17A producing γδ-T-cells enables molecular analysis of targeted therapies aimed at the IL-36γ/IL-23A/IL-17A signalling cascade in psoriasis.
