cGAS-STING drives ageing-related inflammation and neurodegeneration

Bastien Mangeat, Natasha Ella Samson, Andrea Ablasser, Muhammet Fatih Gülen, Sélène-Véronique Glück, Vivek Vijay Thacker, Chong Liu

Low-grade inflammation is a hallmark of old age and a central driver of ageing-associated impairment and disease(1). Multiple factors can contribute to ageing-associated inflammation(2); however, the molecular pathways that transduce aberrant inflammatory ...

The cGAS–STING pathway drives type I IFN immunopathology in COVID-19

Kunal Sharma, Andrea Ablasser, Muhammet Fatih Gülen, Vivek Vijay Thacker, Théo Nass, Martin Schaller

COVID-19, which is caused by infection with SARS-CoV-2, is characterized by lung pathology and extrapulmonary complications1,2. Type I interferons (IFNs) have an essential role in the pathogenesis of COVID-19 (refs 3–5). Although rapid induction of type I ...

m6A methylation potentiates cytosolic dsDNA recognition in a sequence-specific manner

Andrea Ablasser, Muhammet Fatih Gülen

Nucleic acid sensing through pattern recognition receptors is critical for immune recognition of microbial infections. Microbial DNA is frequently methylated at the N-6 position of adenines (m6A), a modification that is rare in mammalian host DNA. We show ...

Targeting STING with covalent small-molecule inhibitors

Gerardo Turcatti, Luc Reymond, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Andrea Ablasser, Muhammet Fatih Gülen, Simone Margret Haag, Michael Christian Heymann, Alexiane Clara Decout

Signalling strength determines proapoptotic functions of STING

Freddy Radtke, Ute Koch, Andrea Ablasser, Muhammet Fatih Gülen

Mammalian cells use cytosolic nucleic acid receptors to detect pathogens and other stress signals. In innate immune cells the presence of cytosolic DNA is sensed by the cGAS-STING signalling pathway, which initiates a gene expression programme linked to ce ...

Innate immune sensing of cytosolic chromatin fragments through cGAS promotes senescence

Andrea Ablasser, Muhammet Fatih Gülen, Sélène-Véronique Glück, Niklas Arndt Schmacke, Baptiste Claude André Guey

The role of cGAS in innate immunity and beyond

Andrea Ablasser, Muhammet Fatih Gülen

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 ...

Mycobacterium tuberculosis Differentially Activates cGAS- and Inflammasome-Dependent Intracellular Immune Responses through ESX-1

Sonia Garcia Perin, Stewart Cole, Claudia Sala, Jan Lars Rybniker, Ye Lou, Andrea Ablasser, Muhammet Fatih Gülen

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 ...

Inside Job: Viruses Transfer cGAMP between Cells

Andrea Ablasser, Muhammet Fatih Gülen

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 ...
