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。

Most individuals with ankylosing spondylitis have the gene HLA-B27, which is a gene that encodes for a specific type of MHC class I molecule.

许多强直性脊柱炎患者都携带HLA-B27基因，该基因能编码一种特定的MHC Ⅰ类分子。

To help with this, most cells in the body have a set of proteins that combine together to form something called a major histocompatibility complex, or MHC, class I molecule that sits on the surface of their cell membrane.

全身多数细胞都有一组蛋白来协助这个过程；这些蛋白结合在一起能形成主要组织相容性复合物（MHC），而MHC Ⅰ类分子就位于细胞膜表面。
