Macrophage training to Borrelia burgdorferi governs cardiac inflammation in the mammalian host [RNA-seq]
Ontology highlight
ABSTRACT: Macrophage exposure to vaccine or vaccine-like formulations results in disparate secondary responses. We have identified the transcriptomic and metabolic changes associated with the memory response of macrophages to Borrelia burgdorferi, an extracellular pathogen able to establish long-term infections in mammals. Memory macrophages show an enhanced ability to bind and internalize the spirochete with decreased inflammatory responses, in part regulated by Irf4. Experienced macrophages also show an augmented glycolytic output. In vivo, glycolysis inhibition results in decreased cardiac inflammation and reduced expression of Irf4. Our data show that B. burgdorferi induces long-term, memory-like responses that are amenable to be manipulated in vivo.
