Zusammenfassung
The inflammatory context of antigen-presentation dictates the outcome of CD8+ T cell responses. Pathogen-induced inflammatory signals ensure the generation of an effector CD8+ T cell response and long-lasting T cell memory, whereas antigen-presentation in absence of inflammatory stimuli, e.g. of self-antigens, causes CD8+ T cell-deletion. The systemic distribution of antigens from certain pathogens without inflammatory stimuli therefore imposes the risk of deleting CD8+ T cells needed for anti-infectious defense. We hence wondered whether cross-presentation of exogenous antigens in the liver, the central organ f…
