The CRL5-SPSB3 ubiquitin ligase targets nuclear cGAS for degradation

Pauline Ambre Melenec, Andrea Ablasser, Jonathan Jean-Pierre Ricci, Baptiste Claude André Guey, Chong Liu, Pengbiao Xu, Ying Liu, Lingyun Li

Cyclic GMP-AMP synthase (cGAS) senses aberrant DNA during infection, cancer and inflammatory disease, and initiates potent innate immune responses through the synthesis of 2 ' 3 '-cyclic GMP-AMP (cGAMP)1-7. The indiscriminate activity of cGAS towards DNA d ...

Interplay of cGAS with chromatin

Andrea Ablasser, Marilena Wischnewski

Recognition of DNA is an evolutionarily highly conserved mechanism of immunity. In mammals, the cGAS-STING pathway plays a central role in coupling DNA sensing to the execution of innate immune mechanisms, both in contexts of infection as well as in noninf ...

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 ...

Regulation of cGAS- and RLR-mediated immunity to nucleic acids

Andrea Ablasser

Pathogen-derived nucleic acids are crucial signals for innate immunity. Despite the structural similarity between those and host nucleic acids, mammalian cells have been able to evolve powerful innate immune signaling pathways that originate from the detec ...

cGAS-STING drives ageing-related inflammation and neurodegeneration

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

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 ...

Colon tumour cell death causes mTOR dependence by paracrine P2X4 stimulation

Andrea Ablasser

Solid cancers exhibit a dynamic balance between cell death and proliferation ensuring continuous tumour maintenance and growth(1,2). Increasing evidence links enhanced cancer cell apoptosis to paracrine activation of cells in the tumour microenvironment in ...

OAS proteins and cGAS: unifying concepts in sensing and responding to cytosolic nucleic acids

Andrea Ablasser

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 ...

The cGAS-STING pathway and cancer

Andrea Ablasser, Natasha Ella Samson

The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway has emerged as a critical innate immune pathway that, following engagement by DNA, promotes distinct immune effector responses that can impact virtually all aspects of tumori ...

Structural mechanism of cGAS inhibition by the nucleosome

Beat Fierz, Andrea Ablasser, Rudolf Hovius, Simone Cavadini, Kristina Makasheva, Baptiste Claude André Guey, Alexiane Clara Decout, Sélène-Véronique Glück, Pauline Ambre Melenec

The DNA sensor cGAS initiates innate immune responses following microbial infection, cellular stress, and cancer1. Upon activation by double-stranded DNA, cytosolic cGAS produces 2’3’ cyclic GMP-AMP and triggers inflammatory cytokine and type I interferon ...

Intracellular bacteria engage a STING-TBK1-MVB12b pathway to enable paracrine cGAS-STING signalling

Andrea Ablasser, Bing Zhang, Thomas Charles Henry Rossi

The innate immune system is crucial for eventual control of infections, but may also contribute to pathology. Listeria monocytogenes is an intracellular Gram-positive bacteria and a major cause of food-borne disease. However, important knowledge on the int ...

Signalling strength determines proapoptotic functions of STING

Freddy Radtke, Andrea Ablasser, Ute Koch, 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 ...
