Mitochondrial dysfunction, specifically the release of mitochondrial DAMPs (mtDAMPs) like oxidized mtDNA and cardiolipin, activates innate immune pathways (NLRP3, cGAS/STING, NF-κB) to drive inflammaging.
Mitochondrial health is crucial for managing inflammation. Impaired mitochondria release signals that trigger chronic inflammation. Physical activity improves mitochondrial function and may help reduce this inflammatory burden.
GoodSupportsHIGH confidence
Impaired mitochondria release DAMPs, composed of mostly oxidatively modified mtDNA and cardiolipin, into the cytosol... When ROS-damaged mtDNA and cardiolipin are released into the cytosol, various inflammatory pathways are activated.
Why this rating
Strong mechanistic evidence from animal models and cell culture; human translational data is emerging.

- Multi-omics approaches (proteomics, transcriptomics) are necessary to accurately measure and understand the complexity of inflammaging, as single biomarkers like IL-6 or TNF-α are insufficient.Strong
- Cellular senescence drives inflammaging through the secretion of the Senescence-Associated Secretory Phenotype (SASP), which promotes chronic sterile inflammation and age-related pathologies.Good
