Among the fibers is the structural protein glial fibrillary acidic protein that is typically found in astrocytes.

这些纤维中有结构状蛋白——胶质纤维酸性蛋白，这些蛋白常存在于星中。

These include astrocytes which have cellular processes coming off their cell body, giving them a star-shaped appearance.

神经胶质包括星胶质，们的体发出许多长而分支的突起，使其呈现星外观。

They are typically named by the cell type involved, so for example an astrocytoma is a tumor formed by mutated astrocytes.

脑肿瘤常以变异的类型命名，比如，星瘤是由变异的星胶质。

Astrocytes are found throughout the brain and spinal cord, and their main roles include maintaining the blood-brain barrier, providing nourishment to neurons, and recycling neurotransmitters.

星遍布大脑和脊髓，们的主要作用是维持血脑屏障，并为神经提供营养以及回收神经递质。

Ammonia appears to mainly target astrocytes, a type of glial cell in the brain, and although the mechanisms aren’t fully understood, ammonia seems to cause astrocyte swelling and oxidative damage.

氨主要出现在星胶质中，是脑内的一种神经胶质，虽然具体的机制我们仍然不清楚，不过氨似乎能导致星胶质肿大和氧化损伤。

Because astrocytes are found through the brain and spinal cord, astrocytomas can form throughout those locations, but juvenile pilocytic astrocytomas are mostly infratentorial tumors in the cerebellum or near the brainstem.

因为星遍布大脑和脊髓，星瘤也可以遍布在这些部位，但青少年毛星瘤大多数是位于小脑内或脑干旁的脑幕下肿瘤。

Histologically, they can have cysts, or sacs filled with fluid; bodies of granular material; and Rosenthal fibers, which are fibers that clump together in the cytoplasm of the astrocyte and look a bit like a worm or a corkscrew.

组织学方面，们可包含囊肿（即充满液体的囊泡）、颗粒体以及嗜伊红性纤维；这些纤维在星的质中聚集簇，看起来有点像蠕虫或是开瓶器的螺旋状部分。
