Novel broad-spectrum virucidal antivirals

Matteo Gasbarri

The current COVID-19 pandemic has showed the threats that viruses can cause to the whole world. Over 200 million infections and over 4.5 million deaths and enormous socio-economic impact were the output of the emergence of a single new pathogen: SARS-CoV-2 ...

Differential roles of GDF15 and FGF21 in systemic metabolic adaptation to the mitochondrial integrated stress response

Johan Auwerx, Jun Yong Kim

Perturbation of mitochondrial proteostasis provokes cell autonomous and cell non-autonomous responses that contribute to homeostatic adaptation. Here, we demonstrate distinct metabolic effects of hepatic metabokines as cell non-autonomous factors in mice w ...

Integrated proteogenomic deep sequencing and analytics accurately identify non-canonical peptides in tumor immunopeptidomes

Didier Trono, George Coukos, Marion Leleu, Evaristo Jose Planet Letschert, Alexandre Harari, Delphine Yvette L Grun, Markus Müller, Florian Huber, Laia Simo Riudalbas

Efforts to precisely identify tumor human leukocyte antigen (HLA) bound peptides capable of mediating T cell-based tumor rejection still face important challenges. Recent studies suggest that non-canonical tumor-specific HLA peptides derived from annotated ...

NCoR1 Protects Mice From Dextran Sodium Sulfate Induced Colitis by Guarding Colonic Crypt Cells From Luminal Insult

Johan Auwerx

BACKGROUND & AIMS: Colonic stem cells are essential for producing the mucosal lining, which in turn protects stem cells from insult by luminal factors. Discovery of genetic and biochemical events that control stem cell proliferation and differentiation can ...

Adjuvant-free immunization with infective filarial larvae as lymphatic homing antigen carriers

Melody Swartz, Alexandre de Titta, Esra Güç, David Scott Wilson, Marcela Rincón-Restrepo, Sachiko Hirosue

Controlled infection with intestinal nematodes has therapeutic potential for preventing the symptoms of allergic and autoimmune diseases. Here, we engineered larvae of the filarial nematode Litomosoides sigmodontis as a vaccine strategy to induce adaptive ...

Disturbed mitochondrial dynamics in CD8(+)TILs reinforce T cell exhaustion

Li Tang, George Coukos, Nicola Vannini, Marcela Rincón-Restrepo, Min Gao

Ho and colleagues report that mitochondrial dysfunction and impaired mitophagy triggered by the tumor microenvironment lead to subsequent epigenetic changes and cause permanent T cell exhaustion and dysfunction. The metabolic challenges present in tumors a ...

Designs and Characterization of Subunit Ebola GP Vaccine Candidates: Implications for Immunogenicity

Florian Maria Wurm, Bruno Emanuel Ferreira De Sousa Correia, Divor Kiseljak, Sarah Wehrle

The humoral responses of Ebola virus (EBOV) survivors mainly target the surface glycoprotein GP, and anti-GP neutralizing antibodies have been associated with protection against EBOV infection. In order to elicit protective neutralizing antibodies through ...

Mitochondrial Deacetylase Sirt3 Reduces Vascular Dysfunction and Hypertension While Sirt3 Depletion in Essential Hypertension Is Linked to Vascular Inflammation and Oxidative Stress

Johan Auwerx

Rationale: Hypertension represents a major risk factor for stroke, myocardial infarction, and heart failure and affects 30% of the adult population. Mitochondrial dysfunction contributes to hypertension, but specific mechanisms are unclear. The mitochondri ...

Molecular profiling and functional analysis of macrophage-derived tumour extracellular vesicles

Tim Beltraminelli

Extracellular vesicles (EVs) are nanosized vesicles released by virtually all cell types. Increasing data suggest that EVs function in the regulation of intercellular communication both in physiological and pathological states. In cancer biology, mounting ...

HIV-1 Vpu is a potent transcriptional suppressor of NF-κB-elicited antiviral immune responses

Jacques Fellay, Christian Hammer

Many viral pathogens target innate sensing cascades and/or cellular transcription factors to suppress antiviral immune responses. Here, we show that the accessory viral protein U (Vpu) of HIV-1 exerts broad immunosuppressive effects by inhibiting activatio ...

The antimicrobial peptide defensin cooperates with tumour necrosis factor to drive tumour cell death in Drosophila

Bruno Lemaitre, Anna Dostalova

Antimicrobial peptides (AMPs) are small cationic molecules best known as mediators of the innate defence against microbial infection. While in vitro and ex vivo evidence suggest AMPs' capacity to kill cancer cells, in vivo demonstration of an anti-tumour r ...
