Anti-inflammatory pathways as a host evasion mechanism for pathogens

Abstract

Lipoxins play a key role in controlling potent pro-inflammatory responses triggered by infection with pathogens, such as Toxoplasma gondii and Mycobacterium tuberculosis. In order to contain microbial dissemination, infected hosts must mount a powerful immune response to prevent mortality. The onset of the chronic phase of infection is characterized by continuous cell-mediated immunity. Such potent responses are kept under tight control by a class of anti-inflammatory eicosanoids, the lipoxins. Here, we review such immune-containment strategies from the host's perspective, to keep pro-inflammatory responses under control during chronic disease, as well as from the perspective of the pathogen, which pirates the host's lipoxygenase machinery to its own advantage as a probable immune-escape mechanism.
