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

在一些结构中，微纤丝为其他白提供支架作用，比如说弹性白。

The tunica externa also has nerve fibers, lymphatic vessels, and in the biggest vessels, the protein elastin.

外膜也有神经纤维、淋巴管，在最大的血管中也有弹性白。

And that includes molecules in the dermis like elastin and collagen, creating tangled clumps or breaking them down.

这些分子又包括像真皮中的弹性白和胶原一的物质，造成结束或分解。

There's also elastin, a protein that gives your skin the ability to bounce back when you stretch it.

一个叫弹性白，也是一种白质，它可以让皮肤在拉扯后迅速还原。

Next there's the tunica media or middle tunic which is mostly made of smooth muscle cells and sheets of elastin protein.

接下来是血管中膜，主要由平滑肌细胞和弹性白组成。

So retinoids can help maintain the structure of your dermis and fight off wrinkles by making your body produce more collagen, elastin, and GAGs.

维生素 A 能促使身体产生更多胶原、弹性白和糖胺聚糖，从有助于保护真皮结构，抵抗皱纹。

Elastin fibers are highly cross-linked, and that gives them a rubber-band-like quality, which allows tissues to stretch and then spring back to their original shape.

弹性纤维高度交联，因此质地如橡皮筋样，这使得组织能够在伸展后回弹至原有形态。

Without alpha-1 antitrypsin, the opposite happens - neutrophil elastase goes unchecked, and it damages the walls of the alveoli, and without that elastin, the alveoli loses its elasticity and structural integrity.

如果没有α-1抗胰白酶，情况就会背道驰：中性粒细胞弹力白酶不受抑制，将会损伤肺泡壁，没有了那层弹性纤维，肺泡壁便失去弹性和结构完整性。

Neutrophils make an enzyme called neutrophil elastase, a protease capable of breaking down elastin, which is an extracellular matrix protein that gives elasticity and strength to lung tissues.

中性粒细胞产生中性粒细胞弹性白酶，该酶能够水解弹性白；弹性白是一种细胞外基质白，赋予肺组织弹性和韧性。

So while these little guys can help fight off infection by breaking down proteins of the bacteria, it can also go on to break down that precious elastin.

因此，当这些战士们在水解细菌白质击溃感染的同时，也可能会进一步水解十分珍贵的弹性白。

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。

Fortunately, the liver makes alpha-1 antitrypsin which gets released into the blood and sent to the lungs, where it inhibits neutrophil elastase just like it inhibits trypsin, inactivating it before it can break down the protein elastin.

幸运的是，肝产生α-1抗胰白酶，释放入血进肺，在肺中像抑制胰白酶一样，抑制中性粒细胞弹性白酶，使弹性白酶在水解弹性纤维之前失活。
