Transcriptomic analysis of WT and Polg D257A/D257A bone marrow derived macrophages (BMDMs) challenged with Pseudomonas aeruginosa

Project description:Mitochondrial diseases (MtD) represent a significant public health challenge due to their heterogenous clinical presentation, often severe and progressive symptoms, and lack of effective therapies. Environmental exposures, such bacterial and viral infection, can further compromise mitochondrial function and exacerbate the progression of MtD. Infections in MtD patients more frequently progress to sepsis, pneumonia, and other detrimental inflammatory endpoints. However, the underlying immune alterations that enhance immunopathology in MtD remain unclear, constituting a key gap in knowledge that complicates treatment and increases mortality in this vulnerable population. This dataset reports transcriptomic changes in bone marrow derived macrophages isolated from wild type (WT) C57BL/6J mice and a mouse model of polymerase gamma (Polg)-related MtD (Polg D257A/D257A), both at rest and six hours after infection with Pseudomonas aeruginosa strain PAO1. These data reveal a hyperinflammatory innate immune status in Polg D257A macrophages characterized by elevated expression of genes involved in interferon and inflammatory cell death pathways. This work sheds new light on innate immune dysregulation in a model of mitochondrial dysfunction and reveals potential targets for limiting infection- and inflammation-related complications in Polg-related MtD.

Proteomic analysis of innate immune responses in Polg D257A macrophages challenged with Pseudomonas aeruginosa

Project description:Mitochondrial diseases (MtD) represent a significant public health challenge due to their heterogenous clinical presentation, often severe and progressive symptoms, and lack of effective therapies. Environmental exposures, such bacterial and viral infection, can further compromise mitochondrial function and exacerbate the progression of MtD. Infections in MtD patients more frequently progress to sepsis, pneumonia, and other detrimental inflammatory endpoints. However, the underlying immune alterations that enhance immunopathology in MtD remain unclear, constituting a key gap in knowledge that complicates treatment and increases mortality in this vulnerable population. This data set utilizes an in vitro assay using Pseudomonas aeruginosa (PA) infection of bone marrow derived macrophages (BMDMs) to clarify the molecular and cellular basis for innate immune hyperactivity in a mouse model of polymerase gamma (Polg)-related MtD. This dataset reports the proteome signatures of WT and Polg D257A mutant BMDMs at rest and 2-8 hours post infection with PA.

Gene-expression data of (WT) and knock-out (KO) bone marrow derived macrophages (BMDMs) from C57BL/7 mice

Project description:We provide gene expression data of wild-type (WT) and various knock-out (KO) bone marrow derived macrophages (BMDMs) from mice (C57BL/6) in different conditions of infections and treatments. We included BMDMs from WT (female and male), Ifnar-/-, IFNg-/-, iNOs-/-, Nlrx1-/- (female and male), Nox2-/- and Prx5-/- mice. BMDMs were either infected with a human protozoan parasite Leishmania guyanensis with or without its endosymbiant double-stranded RNA (dsRNA) virus, Leishmania RNA Virus 1 (LgyLRV1+ and LgyLRV1-, respectively). Alternatively BMDMs were treated with a TLR3 agonist poly I:C, a TLR2 agonist FSL1, with H2O2 or tBHQ.
