Mitochondrial ROS potentiates indirect activation of the AIM2 inflammasome
Activation of the inflammasome is important for the detection and clearance of cytosolic pathogens. In contrast to avirulent Francisella novicida (Fn), infection with virulent Francisella tularensis ssp tularensis does not trigger activation of the host AIM2 inflammasome. Here we show that differential activation of AIM2 following Francisella infection is due to sensitivity of each isolate to r...
متن کاملPKM2-dependent glycolysis promotes NLRP3 and AIM2 inflammasome activation
Sepsis, severe sepsis and septic shock are the main cause of mortality in non-cardiac intensive care units. Immunometabolism has been linked to sepsis; however, the precise mechanism by which metabolic reprogramming regulates the inflammatory response is unclear. Here we show that aerobic glycolysis contributes to sepsis by modulating inflammasome activation in macrophages. PKM2-mediated glycol...
متن کاملSynthetic oligodeoxynucleotides containing suppressive TTAGGG motifs inhibit AIM2 inflammasome activation.
Synthetic oligodeoxynucleotides (ODNs) comprised of the immunosuppressive motif TTAGGG block TLR9 signaling, prevent STAT1 and STAT4 phosphorylation and attenuate a variety of inflammatory responses in vivo. In this study, we demonstrate that such suppressive ODN abrogate activation of cytosolic nucleic acid-sensing pathways. Pretreatment of dendritic cells and macrophages with the suppressive ...
متن کاملMvin mediates Francisella Tularensis virulence through evasion of AIM2 inflammasome activation
ACKNOWLEDGEMENTS I would like to thank my advisors, Drs. William Nauseef and Fayyaz Sutterwala for their support and patience. I would also like to thank my thesis committee for their input. Additionally, I would like to thank everyone in the Inflammation Program. Finally, I would like to thank my family for their endless support. I am especially grateful to my wife Julie for supporting me and ...
متن کاملAIM2 inhibits autophagy and IFN-β production during M. bovis infection
Mycobacteria can trigger the AIM2 inflammasome, autophagy activation and type-I interferon release, which are both activated by cytosolic DNA. We have recently demonstrated that activation of the AIM2 inflammasome during M. bovis infection is the result of mycobacterial translocation into the cytosol. To elucidate the effects of inflammasome activation on autophagy, we investigated the role of ...
