Replication and expression of the mitochondrial genome depend on the sufficient supply ofnucleotide building blocks to mitochondria. Dysregulated nucleotide metabolism is detrimental tomitochondrial genomes and can destabilise mitochondrial DNA and trigger inflammation. Here, wereport that a mitocho...

Cytosolic mitochondrial DNA (mtDNA) elicits a type I interferon response, but signals triggering the release of mtDNA from mitochondria remained enigmatic. We found that mtDNA-dependent immune signaling via the cGAS-STING pathway is under metabolic control and induced by cellular nucleotide deficien...

Metabolic reprogramming of mitochondria occurs during development, cell differentiation and in cancer and is coupled to changes in mitochondrial mass and shape. Here, we demonstrate that the i-AAA protease YME1L rewires the proteome of pre-existing mitochondria in response to hypoxia or nutrient sta...

Metabolic dysregulation can lead to inflammatory responses. Imbalanced nucleotide synthesis triggers the release of mitochondrial DNA (mtDNA) to the cytosol and an innate immune response by cGAS-STING signaling. However, how nucleotide deficiency drives mtDNA dependent inflammation has not been eluc...

Mitochondrial fusion and fission accompany adaptive responses to stress and altered metabolic demands. Inner membrane fusion and cristae morphogenesis depends on Optic Atrophy 1 (Opa1), which is expressed in different isoforms and is cleaved from a membrane-bound, long to a soluble, short form. Here...
