Cytoplasmic dna innate immune pathways

WebJul 18, 2024 · A signaling pathway in eukaryotes known as cGAS–STING recognizes the presence of cytosolic DNA, which alerts the immune system to viral infection or cellular damage. However, the majority of DNA viruses direct their genomic DNA into nuclei, suggesting that nuclear-specific sensing is also needed. L. WebDNA has been known to be a potent immune stimulus for more than half a century. However, the underlying molecular mechanisms of DNA-triggered immune response have remained elusive until recent years. Cyclic GMP-AMP synthase (cGAS) is a major cytoplasmic DNA sensor in various types of cells that detect either invaded foreign DNA …
