Rare predicted loss-of-function variants of type I IFN immunity genes are associated with life-threatening COVID-19

Jacques Fellay, Yu Zhang, Peng Zhang, Qian Zhang

BackgroundWe previously reported that impaired type I IFN activity, due to inborn errors of TLR3- and TLR7-dependent type I interferon (IFN) immunity or to autoantibodies against type I IFN, account for 15-20% of cases of life-threatening COVID-19 in unvac ...

Acute TNF alpha levels predict cognitive impairment 6-9 months after COVID-19 infection

Dimitri Nestor Alice Van De Ville, Alessandra Griffa, Alexandre Cionca, Idris Guessous

Background: A neurocognitive phenotype of post-COVID-19 infection has recently been described that is characterized by a lack of awareness of memory impairment (i.e., anosognosia), altered functional connectivity in the brain's default mode and limbic netw ...

Inborn errors of type I interferon immunity in patients with symptomatic acute hepatitis E

Jacques Fellay

Background and Aims:The clinical spectrum of human infection by HEV ranges from asymptomatic to severe acute hepatitis. Furthermore, HEV can cause diverse neurological manifestations, especially Parsonage-Turner syndrome. Here, we used a large-scale human ...

Defining and targeting tumor-associated macrophages in malignant mesothelioma

Michele De Palma

Defining the ontogeny of tumor-associated macrophages (TAM) is important to develop therapeutic targets for mesothelioma. We identified two distinct macrophage populations in mouse peritoneal and pleural cavities, the monocyte-derived, small peritoneal/ple ...

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

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

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 ...

Variability of Primary Sjogren's Syndrome Is Driven by Interferon alpha and Interferon alpha Blood Levels Are Associated With the Class II HLA-DQ Locus

Jacques Fellay, Christian Axel Wandall Thorball, Nicolas Meyer

Objective Primary Sjogren's syndrome (SS) is the second most frequent systemic autoimmune disease, affecting 0.1% of the general population. To characterize the molecular and clinical variabilities among patients with primary SS, we integrated transcriptom ...

A Baseline Cellular Antiviral State Is Maintained by cGAS and Its Most Frequent Naturally Occurring Variant rs610913

Jacques Fellay, Christian Axel Wandall Thorball, Shuting Xu

Upon recognition of aberrantly located DNA, the innate immune sensor cyclic GMP-AMP synthase (cGAS) activates stimulator of IFN genes (STING)/IFN regulatory factor (IRF)3-driven antiviral responses. In this study, we characterized the ability of a specific ...

Monocyte-derived macrophages aggravate pulmonary vasculitis via cGAS/STING/IFN-mediated nucleic acid sensing

Andrea Ablasser

Kessler et al. identify aberrant DNA recognition by cGAS/STING and IFN-I production by inflammatory macrophages as a driver of severe ANCA-associated vasculitis. Pharmacological interventions blocking this pathway ameliorate disease and accelerate recovery ...

Clathrin-associated AP-1 control stermination of STING signalling

Andrea Ablasser, Jonathan Jean-Pierre Ricci, Chong Liu, Pengbiao Xu, Ying Liu, Sophie Marie Elisabeth Rivara

Stimulator of interferon genes (STING) functions downstream of cyclic GMP-AMP synthase in DNA sensing or as a direct receptor for bacterial cyclic dinucleotides and small molecules to activate immunity during infection, cancer and immunotherapy(1-10). Prec ...

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 ...

Preexisting Heterogeneity of Inducible Nitric Oxide Synthase Expression Drives Differential Growth of Mycobacterium tuberculosis in Macrophages

John McKinney, Ophélie Rutschmann, Chiara Toniolo

Mycobacterium tuberculosis infection is initiated by the inhalation and implantation of bacteria in the lung alveoli, where they are phagocytosed by macrophages. Even a single bacterium may be sufficient to initiate infection. Thereafter, the clinical outc ...
