A recent study also showed that mitochondrial stress or dysfunction could trigger mitochondrial DNA release into the cytosol, with activation of the cGAS-STING-mediated innate immune response. Accessibility Because IFN-β production is triggered by nucleic acids in general [12, 14], we hypothesized that the IFN-β upregulation might be mediated by mtDNA released from Ply-induced mitochondrial damage. This allows you to focus on the securities you are interested in, so you can make informed decisions. DNA sensors participate in the response to many pathogens, including bacteria, fungi, and viruses, and mediate their clearance. Discussions of the role of cell death in AIDS, inflammatory disease, lung and cardiac disease, and lupus each emphasize the importance of understanding and regulating inflammation and the production of apoptotic bodies. Using mitochondrial-targeted TALENs, we show that mtDSBs activate a type I interferon response evidenced by phosphorylation of STAT1 and activation of interferon stimulated genes (ISG). Mitochondria are important cellular organelles involved in many different functions, from energy generation and fatty acid oxidation to cell death regulation and immune responses. Trends Genet.

Significance: Mitochondria, vital cellular power plants to generate energy, are involved in immune responses. Loss of the caspase cascade Then, following DNA damage and micronuclei formation, cGAS may re-localize to the micronuclei bodies and recognize micronuclear DNA, followed by initiation of downstream signal activation. Furthermore, a battery of mitochondrial components/mediators has been identified to act as DAMPs to trigger and sustain an immune response in multiple pathologies (Table 1).

With the explosion of information on autophagy in cancer, this is an opportune time to speed the efforts to translate our current knowledge about autophagy regulation into better understanding of its role in cancer. As mitochondria are pivotal in the immune response and many viruses in turn modulate mitochondria [22, 23], it is possible that altered mitochondrial function may explain at least some of the variance in responses to SARS-CoV-2.

Bak- and Bax-mediated mitochondrial damage triggers the release of mitochondrial DNA (mtDNA), which is recognized by the cGAS/STING-mediated cytosolic DNA sensing pathway. cGAS functions as a DNA sensor. 2014 Oct;44(10):2847-53. doi: 10.1002/eji.201344407. Mitochondrial damage causes various cellular events such as reactive oxygen species (ROS) production and caspase-9 and voltage-dependent anion channel activation, and is often involved in innate immune responses . Accumulating evidence indicates that mitochondrial stress acts as a key trigger of innate immune responses. Upon binding to mtDNA, cGAS promotes the recruitment of STING protein, which triggers the phosphorylation of the transcription factor IRF-3 through the TANK (TRAF family member-associated NF-κB activator)-binding kinase and . Additionally, recent studies have shown that cell cycle progression during mitosis following a DNA-damage response may lead to formation of micronuclei, thereby eliciting a cGAS/STING-mediated micronuclear DNA-sensing immune response 14, 15.

The innate immune system plays an important role in the mammalian immune response. Induction of nucleic acid sensing-mediated type I interferon (IFN) has emerged as a novel approach to activate the immune system against cancer. mtDNA stress may contribute to cyclic GMP-AMP synthase (cGAS) stimulator of interferon genes (STING) pathway activation in infectious diseases. It will be intriguing to test whether cGAS itself may be a direct target of caspases. The efficacy of several therapeutic strategies against cancer, including cytotoxic drugs, radiotherapy, targeted immunotherapies and oncolytic viruses, depend on intact type I interferon (IFN) signaling for the promotion of both direct (tumor cell inhibition) and indirect (anti-tumor immune responses) effects. Breaks in mitochondrial DNA cause leakage of mitochondrial RNA into the cytoplasm, enhancing immune surveillance and synergizing with nuclear DNA damage to mount a robust type-I interferon immune .
