The sensing of foreign DNA is crucial for host defense against several pathogens. In the cytosol the enzyme cyclic GMP-AMP synthase (cGAS) is critical for the recognition of pathogen-derived DNA and provides key signals that initiate immune responses. Beyo ...
Cytosolic detection of microbial products is essential for the initiation of an innate immune response against intracellular pathogens such as Mycobacterium tuberculosis (Mtb). During Mtb infection of macrophages, activation of cytosolic surveillance pathw ...
The DNA sensor, cyclic GMP-AMP synthase (cGAS), is essential for the detection of viral infection. In a recent issue of Science, two studies, Bridgeman et al. (2015) and Gentili et al. (2015), report a novel mechanism for propagating an antiviral signal be ...
Recent discoveries in the field of innate immunity have highlighted the existence of a family of nucleic acid-sensing proteins that have similar structural and functional properties. These include the well-known oligoadenylate synthase (OAS) family protein ...
