Abstract
Upon various stresses, mtDNA leaks from mitochondria into the cytoplasm, leading to cellular dysfunction and inflammation, thereby exacerbating disease progression. The autophagy-lysosome pathway has emerged as a pivotal quality control mechanism for eliminating abnormal cytoplasmic mtDNA. This article summarizes the mechanisms underlying mtDNA-triggered inflammation and how cytoplasmic mtDNA is eliminated.
期刊介绍：
Trends in Cell Biology stands as a prominent review journal in molecular and cell biology. Monthly review articles track the current breadth and depth of research in cell biology, reporting on emerging developments and integrating various methods, disciplines, and principles. Beyond Reviews, the journal features Opinion articles that follow trends, offer innovative ideas, and provide insights into the implications of new developments, suggesting future directions. All articles are commissioned from leading scientists and undergo rigorous peer-review to ensure balance and accuracy.
