Basis of rejection

The function of the HLA/MHC system is not to make transplantation difficult. It is to protect the body against attack by foreign viri, bacteria etc.

In essence rejection is due to the recipients T-cell receptor mistaking foreign MHC in the graft for self MHC bound to foreign antigen. This triggers the immune system to start attacking the donors cells that are expressing MHC.
