在PE胎盘中的免疫微环境,特别是关于妊娠糖尿病 (GDM),尚未完全理解.

研究的目的:

综合分析PE患者胎盘中的免疫细胞格局.
为了区分PE,GDM和组合GDM&PE之间的免疫微环境.

主要方法:

使用流细胞计 (通过飞行时间进行细胞计) 来量化免疫细胞群.
单细胞RNA测序用于研究细胞相互作用和分子机制.

主要成果:

在PE胎盘中,增加了类似记忆的Th17细胞,类似记忆的CD8+T细胞和亲炎性巨细胞 (亲炎性Macs).
在PE中观察到抗炎性巨细胞和颗粒细胞髓质衍生抑制细胞 (gMDSCs) 的减少.
来自PE小鼠的促炎Macs通过促进特定的T细胞反应和抑制gMDSCs,在正常怀孕的小鼠中诱导PE类症状.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
