Excerpt
Influenza-related mortality is often caused by secondary bacterial pneumonia. We have previously shown that the tryptophan-catabolizing enzyme indoleamine-2,3-dioxygenase (IDO) critically impairs host defense against secondary bacterial pneumonia [
1]. Since inhibition of IDO resulted in increased neutrophil numbers during primary viral infection, we hypothesized that tryptophan degradation and/or the generation of downstream metabolites induces neutrophil apoptosis. In the present study we aimed to investigate the impact of IDO-mediated tryptophan metabolism on neutrophil apoptosis
in vitro and in
vivo. …
