Acute and chronic viral infections remain a major public health concern yet most external factors affecting efficacy of anti-viral immunity remain poorly understood. Based on our previous results demonstrating enhanced immunopathology and impaired virus control in germfree and in mice with limited bacterial diversity (OligoMM12-colonized mice) after chronic LCMV infection, we will now assess particularities of OligoMM12 consortia and derivatives thereof during the course of the infection and investigate mechanistic links of these particularities to the regulation of virus-specific cytotoxic and T helper cell responses in different tissues. These mechanistic insights may be highly useful for the rational design of more efficient and personalized vaccination regimens and anti-cancer therapies including checkpoint inhibition.
