Body odour is known to be linked with genetic make-up (particularly with the genes underlying part of the immune system called the major histocompatibility complex).

众所周知，体味与遗传构成有关(特别是与免疫系统中被称为主要组织相容性复合体的潜在基因)。

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。
