Autoimmune hepatitis can be split into two types.

自身免疫性肝炎可以分为2种。

Decreased serum albumin is also a marker for autoimmune hepatitis and damage to the liver.

血清蛋白减少也是自免肝以及肝损的标志。

This young man eventually developed autoimmune hepatitis due to his eating habits and passed away at the early age of 20.

这个年轻人最终由于饮食习惯患上了自身免疫性肝炎，在 20 岁时就去世了。

Based on studying people with autoimmune hepatitis, they often have HLA-DR3 and -DR4, which are both MHC class II surface receptors.

基于对自免肝病人的研究，他们（的体细胞表面）常常含有HLA-DR3和HLA-DR4，两者都是MHC-II类分子。

Type 1 is the most common, accounting for about 80% of autoimmune hepatitis cases, and is characterised by several lab findings.

1型最常见，占自免肝病例中的80%，以一些实验室检查结果为特点。

So, specifically with autoimmune hepatitis, there seems to be some sort of connection between these particular " self-proteins" , the HLA-DR, and mounting an attack against your own liver.

具体来说，对于自免肝来说，HLA-DR这些特殊的“自身蛋白”似乎与免疫系统攻击自己的肝脏之间有某种联系。

Like many autoimmune diseases, the root cause of autoimmune hepatitis is, ultimately, not super clear, but some researchers think it's a combination of environmental triggers and genetic predisposition.

和很多自身免疫性疾病一样，自免肝的根本病因并不明确，但有些学者认为是环境诱因和遗传易感性的综合作用。

Autoimmune hepatitis also tends to be associated with other diseases, like Hashimoto's thyroiditis, where your immune cells attack your thyroid, and Grave's disease, where your thyroid overproduces thyroid hormones.

自免肝常与其它疾病伴发，比如桥本氏甲状腺炎，此时免疫系统攻击你的甲状腺，还有会导致甲状腺产生过多甲状腺激素的Grave's病。

Type 2 autoimmune hepatitis is way less common, and is defined by the presence of antibodies to the microsomes of the liver or your kidney, ALKM-1, or to a liver cytosol antigen, ALC-1.

2型自免肝更加罕见，它的定义是机体存在肝脏或肾脏微粒体抗体ALKM-1，或者抗肝细胞溶胶抗原抗体ALC-1。

Hepatitis happens to mean inflammation of the liver, so it's reasonable to say that autoimmune hepatitis is this resulting inflammation of your liver tissue, because they're being attacked by your own immune cells.

Hepatitis意为肝的炎症，说自免肝是肝组织炎症的结果也未尝不可，因为肝组织被你自己的免疫细胞攻击了。
