Host genetics play a critical role in controlling CD8 T cell function and lethal immunopathology during chronic viral infection.

ABSTRACT: Effective CD8 T cell responses are vital for the control of chronic viral infections. Many factors of the host immune response contribute to the maintenance of effector CD8 T cell responses versus CD8 T cell exhaustion during chronic infection. Specific MHC alleles and the degree of MHC heterogeneity are associated with enhanced CD8 T cell function and viral control during human chronic infection. However, it is currently unclear to what extent host genetics influences the establishment of chronic viral infection. In order to examine the impact of MHC heterogeneity versus non-MHC host genetics on the development of chronic viral infection, an F1 cross of B10.D2 x B6 (D2B6F1) and BALB.B x BALB/c (BCF1) mice were infected with the clone-13 (Cl-13) strain of lymphocytic choriomeningitis virus
