DNA damage sensor MRE11 recognizes cytosolic double-stranded DNA and induces type I interferon by regulating STING trafficking.

Abstract

Double-stranded DNA (dsDNA) derived from pathogen- or host-damaged cells triggers innate immune responses when exposed to cytoplasm. However, the machinery underlying the primary recognition of intracellular dsDNA is obscure. Here we show that the DNA damage sensor, meiotic recombination 11 homolog A (MRE11), serves as a cytosolic sensor for dsDNA. Cells… (More)
