Viral Infection and immunity
... The Role of MHC • In humans, the MHC is located on the short arm of chromosome 6 and spans approximately 4 megabases of DNA. It can be divided into three regions termed class I, class II and class III: • The class III region contains genes which encode a number of complement components and the tumo ...
