对于细胞粘附至关重要的德斯莫索姆在脏疾病中受到上调. 德斯莫格林-2 (Dsg2) 删除会加剧损伤,这表明Dsg2可以保护管损伤.
科学领域:
- 细胞生物学 细胞生物学
- 脏生理学 脏生理学
- 组织工程是组织工程.
背景情况:
- 德斯莫索姆是重要的细胞-细胞粘附结构,主要研究在皮肤和心脏中.
- 它们在承受机械压力的脏中的作用仍然在很大程度上未被探索.
研究的目的:
- 为了研究管状上皮细胞中脱体的存在和作用.
- 为了确定德斯莫格林-2 (Dsg2) 在损伤中的功能.
主要方法:
- 免疫光显微镜用于在健康和患病脏中定位体内蛋白质.
- 从四种动物模型和人类患者活检中分析脏组织.
- 产生和评估管状上皮细胞特异性的Dsg2淘汰小鼠.
- 在体外研究中使用具有DSG2沉默的HK-2细胞.
主要成果:
- 在健康的管中,desmosomal蛋白质存在于结结复合体.
- 在各种脏疾病中,desmosomal成分,特别是Dsg2,被上调和错位化.
- Dsg2淘汰赛小鼠在管道损伤后表现出加剧的损伤反应 (亡,增殖,缩,炎症).
- 在体外,DSG2沉默会损害细胞-细胞粘附,增加细胞死亡.
结论:
- 管状细胞在各种物种和疾病中表现出突出的desmosome上调.
