- 研究BBM在败血症模型中的保护作用.
- 阐明BBM的机制,重点关注免疫调节和Notch1信号通路.
主要方法:
- 使用了鼠类败血症模型 (LPS诱导的内毒素和CLP诱导的败血症).
- 进行了基因病理学,细胞因子和流动细胞计分析.
- 使用骨髓衍生的巨细胞 (BMDMs) 进行了体外测定.
- 雇佣了网络药理学和CETSA来识别分子标,特别是Notch1信号.
- 评估了BBM对神经细胞特异性Notch1淘汰 (Notch1MKO) 鼠标的影响.
主要成果:

Notch Signaling Pathway
4.5K
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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.2K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
