Description:
Alterations of mitochondrial functions are linked to multiple degenerative or acute diseases. As mitochondria age in our cells, they become progressively inefficient and potentially toxic, and acute damage can trigger the permeabilization of mitochondrial membranes to initiate apoptosis or necrosis. Moreover, mitochondria have an important role in pro-inflammatory signaling. Autophagic turnover of cellular constituents, be it general or specific for mitochondria (mitophagy), eliminates dysfunctional or damaged mitochondria, thus counteracting degeneration, dampening inflammation, and preventing unwarranted cell loss. Decreased expression of genes that regulate autophagy or mitophagy can cause degenerative diseases in which deficient quality control results in inflammation and the death of cell populations. Thus, a combination of mitochondrial dysfunction and insufficient autophagy may contribute to multiple aging-associated pathologies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3405151/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3405151/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Douglas R -- Galluzzi, Lorenzo -- Kroemer, Guido -- R01 AI040646/AI/NIAID NIH HHS/ -- R01 AI047891/AI/NIAID NIH HHS/ -- R01 GM096208/GM/NIGMS NIH HHS/ -- R37 GM052735/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1109-12. doi: 10.1126/science.1201940.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, St. Jude Children's Research Hospital, Memphis, TN 38105, USA. douglas.green@stjude.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21868666" target="_blank"〉PubMed〈/a〉
