Chimeric mice are generated where approximately 50% of the cells in the animal are genetically MHC class I-deficient.
Firdavs [7]

Chimeric mice are generated where approximately 50% of the cells in the animal are genetically MHC class I-deficient. The other 50% are deficient for the herpes virus receptor, HVEM, but do express MHC class I molecules. When these mice are infected with herpesvirus by intraperitoneal injection, a robust virus-specific CD8 T cell response is detected at day 7 post-infection in the spleens of the infected mice.
