概括
非热大气压等离子体 (NTAPP) 介质的暴露暂时减少皮肤细胞中的克劳丁-1 (CLDN1),影响屏障功能. 这种效应是可逆的,这表明潜在的增强透皮药物输送.
科学领域:
- 皮肤病学和生物医学工程
- 研究新型等离子体技术对皮肤生理学的影响.
背景情况:
- 皮肤的表皮屏障功能依赖于紧密的结节 (TJs),特别是克劳丁-1 (CLDN1).
- 非热气压等离子体 (NTAPP) 在皮肤病学中表现有前途,但其对皮肤细胞的间接影响尚不清楚.
研究的目的:
- 阐明NTAPP处理介质 (PAM) 对人类角质细胞上皮肤TJ屏障功能的影响.
- 研究NTAPP诱导的CLDN1表达和局部化的变化背后的分子机制.
主要方法:
- 人类表皮角质细胞 (HaCaT) 细胞被用PAM治疗.
- 分析了克劳丁-1 (CLDN1) 蛋白表达和局部化.
- 测量了体电阻 (TEER) 和细胞透性.
主要成果:
- PAM治疗显著降低了CLDN1蛋白表达及其在细胞与细胞接触处的局部化.
- 这些变化与通过克拉林依赖性内细胞分解的溶酶体降解有关.
- PAM治疗降低了TEER,并增加了对低分子量化合物的透性,表明屏障减弱.
结论:
- 用NTAPP处理的介质通过减少CLDN1在角质细胞中的局部化,暂时损害了表皮TJ屏障.
- 观察到的效应在停止PAM治疗后是可逆的.
- 通过调节皮肤屏障的透性,NTAPP技术有可能提高通过皮肤传递的药物.

Tight Junctions
5.6K
Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...

Hedgehog Signaling Pathway
7.5K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
