A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation

Didier Trono, Priscilla Turelli, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Florian Huber, Olga Marie Louise Rosspopoff, Romain Forey, Sandra Eloise Kjeldsen, Cyril David Son-Tuyên Pulver, Joana Carlevaro Fita

Heterochromatin loss and genetic instability enhance cancer progression by favoring clonal diversity, yet uncontrolled replicative stress leads to mitotic catastrophe and inflammatory responses that promote immune rejection. KRAB domain-containing zinc fin ...

The CRL5-SPSB3 ubiquitin ligase targets nuclear cGAS for degradation

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

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 ...

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 ...

Type I IFNs link skin-associated dysbiotic commensal bacteria to pathogenic inflammation and angiogenesis in rosacea

Alessio Mylonas, Yichen Wang, Jiaqi Chen

Rosacea is a common chronic inflammatory skin disease with a fluctuating course of excessive inflammation and apparent neovascularization. Microbial dysbiosis with a high density of Bacillus oleronius and increased activity of kallikrein 5, which cleaves c ...

Engineering Innate and Adaptive Immunity for Enhanced Cancer Immunotherapy

Min Gao

Cancer immunotherapy has become an attractive strategy among different therapeutic modalities over the past few years and has showed great success in the clinic. However, there are many outstanding challenges hindering the current immunotherapies. In my Ph ...

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, Vivek Vijay Thacker, Théo Nass, 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 ...
