The main component of microfibrils is a glycoprotein called fibrillin.

这些微纤丝的主要成分是一种糖蛋白，叫做原纤蛋白。

In some structures microfibrils form a scaffold for additional proteins like elastin.

在一些结构中，微纤丝为其他蛋白提供支架作用，比如说弹性蛋白。

In addition to being part of microfibrils, fibrillin also regulates tissue growth.

原纤蛋白除了构成微纤丝之外，还能调节组织生长。

As a result, there are fewer functioning microfibrils in the extracellular matrix, and that means there's less tissue integrity and elasticity.

这会导致细胞外基质中正常的微纤丝减少，造成组织完整性和弹性下降。

Tissues that have elastin fibers are tissues like the arteries, skin, and lungs, and tissues that have microfibrils but no overlying layer of elastin are like tendons and the ciliary zonules that hold the eye lens in place.

弹性纤维存在于动脉、皮肤、肺等组织，无弹性蛋白但含有微纤丝的组织包括肌腱以及维持晶状体正常位置的睫状带等。
