Karakterizacija i raznolikost gena DQB skupine II glavnog sustava tkivne podudarnosti u mrkog medvjeda (Ursus arctos) [PDF]
, 2018 Glavni sustav tkivne podudarnosti (engl. major histocompatibility complex, MHC) ključan je u pokretanju obrambenih mehanizama kralježnjaka, a smatra se da su neki od lokusa MHC među najpolimorfnijim u kralježnjaka. Raznolikost gena MHC utječe na sposobnost populacije da se obrani od različitih patogena.
