MND is an incurable condition in which the nerve cells controlling the muscles that enable people to move, speak, swallow and breathe, fail to work. doi: 10.15252/embr.201949799. TDP-43 Triggers Mitochondrial DNA Release via mPTP to Activate cGAS/STING in ALS TDP-43 causes inflammation in ALS by stimulating mitochondrial DNA release, which is subsequently sensed by the cytosolic cGAS/STING pathway, suggesting that inhibition of cGAS/STING could help alleviate inflammation-related damage in ALS. 9 Cell lysates were transfected with LonP1-expressing plasmid and . TDP-43 is a transcriptional repressor that binds to chromosomally integrated TAR DNA and represses HIV-1 transcription. Pharmacologic inhibition or genetic deletion of cGAS and its downstream signaling partner STING prevents upregulation of NF-B and type I IFN induced by TDP-43 in induced pluripotent stem cell (iPSC)-derived motor neurons and in TDP-43 mutant mice. Found insideThe book provides chapters on sex hormones and their modulation in neurodegenerative processes and pathologies, from basic molecular mechanisms, physiology, gender differences, to neuroprotection and clinical aspects for potential novel TDP-43 aggregation induced by oxidative stress causes global mitochondrial imbalance in ALS. title = "TDP-43 Triggers Mitochondrial DNA Release via mPTP to Activate cGAS/STING in ALS", abstract = "Cytoplasmic accumulation of TDP-43 is a disease hallmark for many cases of amyotrophic lateral sclerosis (ALS), associated with a neuroinflammatory cytokine profile related to upregulation of nuclear factor B (NF-B) and type I interferon . Changes to the TDP-43 protein cause the protein to misfold and form protein clumps, which have been found in nerve cells that control motor neurons in some people with ALS.

Regulation of anion channel LRRC8 volume-regulated 2021. This book provides a cutting-edge review of polyglutamine disorders. Our results identify mtDNA release and cGAS/STING activation as critical determinants of TDP-43-associated pathology and demonstrate the potential for targeting this pathway in ALS. Mitochondria (blue) provide power to motor neurons, but if invaded by TDP-43, they leak out their DNA (green) which triggers a virus sensor called STING.
