Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Recognition of pathogen-derived molecules through germline-encoded receptors is a fundamental principle of innate immunity. Pattern recognition receptors detect specific intracellular danger signals to trigger potent immune responses. The DNA sensor cyclic ...

EPFL2022

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 ...

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 ...

Emerging dimensions of cellular cGAS-STING signaling

Andrea Ablasser, Baptiste Claude André Guey

The recognition of DNA through the cGAS-STING pathway plays a critical role in antiviral immunity, but can also drive maladaptive immune responses underlying several pathological conditions. Despite its importance, understanding the organization of cGAS-ST ...

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 ...

Human genomics of the humoral immune response against polyomaviruses

Jacques Fellay, Christian Axel Wandall Thorball, Zhi Ming Xu, Olivier Noël Marie Naret, Christian Hammer, Flavia Aurelia Shoko Hodel, Petar Scepanovic

Human polyomaviruses are widespread in humans and can cause severe disease in immunocompromised individuals. To identify human genetic determinants of the humoral immune response against polyomaviruses, we performed genome-wide association studies and meta ...

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 ...

The Drosophila Baramicin polypeptide gene protects against fungal infection

Bruno Lemaitre, Mark Austin Hanson, Igor Iatsenko, Alice Marra

The fruit fly Drosophila melanogaster combats microbial infection by producing a battery of effector peptides that are secreted into the haemolymph. Technical difficulties prevented the investigation of these short effector genes until the recent advent of ...

cGAS regulation and activity during genotoxic stress

Sélène-Véronique Glück

The innate immune system has evolved to detect pathogens through germlineencoded pattern recognition receptors (PRRs). Nucleic acid sensors, a defined class of PRRs, bind to microbial and viral nucleic acids and trigger the production of type I interferons ...

BAF restricts cGAS on nuclear DNA to prevent innate immune activation

Mahmut Selman Sakar, Beat Fierz, Andrea Ablasser, Baptiste Claude André Guey, Alexiane Clara Decout, Murat Kaynak, Kristina Makasheva, Marilena Wischnewski

The appearance of DNA in the cytosol is perceived as a danger signal that stimulates potent immune responses through cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS). How cells regulate the activity of cGAS toward self-DNA and guard a ...
