银屑病是一种由皮肤T细胞慢性活化引起的遗传性疾病。阐明所涉及的细胞亚群的相互作用机制是开发下一代有效治疗方法的关键。在这个问题上,Bovenschen等人报道了调节性T细胞在转录因子Foxp 3和RORγt之间保持着良好的平衡。在银屑病患者中,TGFAP很容易转化为表达IL-17的细胞,从而可能使作为该疾病特征的炎症过程永久化。结果表明,组蛋白/蛋白脱乙酰化抑制剂阿司他丁A可以阻断这种转换表明,表观遗传修饰可能是调节T细胞可塑性的基础。
Psoriasis is a hereditary disease elicited by chronic activation of cutaneous T cells. Delineating the mechanistic interplay of the cell subsets involved is key to developing the next generation of effective treatments. In this issue, Bovenschen et al. report that regulatory T cells maintain a fine balance between the transcription factors Foxp3 and RORγt. In patients with psoriasis, Tregs readily turn into IL-17-expressing cells, thus potentially perpetuating the inflammatory process that characterizes the disease. Results demonstrating that the histone/protein deacetylation inhibitor trichostatin A can block this conversion suggest that an epigenetic modification may underlie regulatory T-cell plasticity.
