These then get into the mother's circulation and cause the endothelial cells that line her blood vessels to become dysfunctional.

之后它们进入母体的血液循环，导致血管表面的内皮细胞功能障碍。

The innermost tunic is called the tunica intima, which includes the endothelial cells, which create a slick surface that minimizes friction for blood moving through it.

最内层者称为内膜，有内皮细胞构成；它们形成了光滑表面，使血液流经时的摩擦降到最低。

HHV-8 is transmitted through sexual contact, and once in the body, it uses the viral glycoproteins on its envelope to enter a wide variety of cells, such as B cells, endothelial cells, macrophages and epithelial cells.

HHV-8通过性接触传播，一旦进入宿主体内，它会利用囊膜上的病毒糖蛋白进入多种细胞内，例如B细胞、内皮细胞、巨噬细胞与上皮细胞。

Now, the sudden gush of blood through the collateral vessel stretches its walls and deforms the endothelial cells, which stimulates the production of growth factors like the vascular endothelial growth factor, or VEGF, from the vessel wall.

现在，一股血流突然涌入侧支血管，牵拉血管壁使内皮细胞变形，刺激血管壁产生生长因子，如血管内皮生长因子（VEGF）。
