利用基因工程小鼠模型来理解NS并识别治疗点.
评估抑制特定KLK蛋白酶作为NS治疗的潜力.

主要方法:

产生和分析Spink5缺乏的小鼠模型,包括双重和三重淘汰策略.
在小鼠模型中评估表皮屏障功能,炎症和皮肤脱落.
针对KLK蛋白酶 (KLK5,KLK7) 和TNFα的治疗干预措施的评估.

主要成果:

缺少Spink5的小鼠回顾了人类NS的关键特征,但表现出新生儿死亡率.
抑制KLK蛋白酶,特别是KLK5,对皮肤表现有显著的治疗效果.
对KLK5,KLK7和TNFα的联合抑制是拯救小鼠中致命的表型所必需的.

结论:

失调的KLK蛋白酶活性是Netherton综合征病理学的核心.
准KLK蛋白酶,特别是KLK5,为NS提供了一个有前途的治疗策略.
鼠类模型对于理解NS病变发生和验证潜在的药物候选者至关重要.

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
