Web24 jul. 2024 · The ability of mammalian cells to sense invading pathogens by cellular pattern recognition receptors is crucial for mounting of an effective cellular defense response and for initiating adequate adaptive immunity. cGMP-AMP synthetase (cGAS) senses DNA of aberrant subcellular localization in a sequence-independent, but length-dependent manner. WebCyclic GMP-AMP synthase (cGAS) recognizes cytoplasmic DNA and signals via STING to induce IFN production. Despite the importance of DNA in innate immunity, the nature of the DNA that stimulates IFN production is not well described. Using low DNA concentrations, we show that dsDNA induces IFN in a length-dependent manner.
