MLH1 Deficiency-Triggered DNA Hyperexcision by Exonuclease
The cytosolic DNA sensor cyclic GMP-AMP synthase (cGAS), a critical factor in the innate immune response pathway, is essential for checkpoint blockade immunotherapy in animal …
New frontiers in the cGAS-STING intracellular DNA-sensing pathway
2024年4月9日 · The cGAS-STING DNA-sensing pathway has emerged as a central mediator of host defense, a cause of numerous human immune diseases, a contributor to fundamental …
MLH1 Deficiency-Triggered DNA Hyperexcision by Exonuclease …
2021年1月11日 · While neoantigens result from the hypermutable nature of dMMR, it is unknown how dMMR activates the cGAS-STING pathway. We show here that loss of the MutLα subunit …
