Identifying genetic and dietary modulators of metabolic disorders using systems genetics

Xiaoxu Li

Long-term consumption of lipid-rich foods can contribute to common metabolic diseases and systemic low-grade inflammation. However, dietary responses and the development of non-communicable diseases are shaped by genetic factors and gene-by-environment int ...

Neonatal-Onset Familial Mediterranean Fever in an Infant with Human Parainfluenza Virus-4 Infection

Alessandro Borghesi

Unusual, severe infections or inflammatory episodes in newborns and infants are largely unexplained and often attributed to immature immune responses. Inborn errors of immunity (IEI) are increasingly recognized as the etiology of life-threatening inflammat ...

Growth differentiation factor 15 protects against the aging-mediated systemic inflammatory response in humans and mice

Johan Auwerx, Dongryeol Ryu, Jun Yong Kim, Ludger Jan Elzuë Goeminne

Mitochondrial dysfunction is associated with aging-mediated inflammatory responses, leading to metabolic deterioration, development of insulin resistance, and type 2 diabetes. Growth differentiation factor 15 (GDF15) is an important mitokine generated in r ...

Multicomponent Alginate-Derived Hydrogel Microspheres Presenting Hybrid Ionic-Covalent Network and Drug Eluting Properties

Sandrine Gerber, François Rémi Pierre Noverraz, Luca Szabó

The development of multifunctional encapsulation biomaterials could help the translation of cell‐based therapies into standard medical care. One of the major hurdles in the field of encapsulated cell transplantation is the current lack of materials present ...

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 ...

Nanoparticle-enhanced Imaging Based Plasmonic Biosensor

Alexander Belushkin

Efficient medical care fundamentally relies on the ability to provide a timely and accurate diagnosis. Thanks to advances in biomedical research, specific molecules called diagnostic molecular biomarkers have been discovered in the human body that help ind ...

Human proteinase 3 resistance to inhibition extends to alpha-2 macroglobulin

Marc Moniatte

Polymorphonuclear neutrophils contain at least four serine endopeptidases, namely neutrophil elastase (NE), proteinase 3 (PR3), cathepsin G (CatG), and NSP4, which contribute to the regulation of infection and of inflammatory processes. In physiological co ...

Identification and characterisation of small-molecule inhibitors targeting STING

Simone Margret Haag

The recognition of pathogen-derived nucleic acids is a critical mechanism by which the innate immune system detects viral infection. Upon activation, nucleic acid sensors initiate the expression of type I interferons and other inflammatory mediators, subse ...

Combining landscape genomics and ecological modelling to investigate local adaptation of indigenous Ugandan cattle to East Coast fever

Stéphane Joost, Estelle Rochat, Elia Vajana

East Coast fever (ECF) is a fatal sickness affecting cattle populations of eastern, central, and southern Africa. The disease is transmitted by the tick Rhipicephalus appendiculatus, and caused by the protozoan Theileria parva parva, which invades host lym ...

Plasma Membrane-bound G Protein-coupled Bile Acid Receptor Attenuates Liver Ischemia/Reperfusion Injury Via the Inhibition of Toll-like Receptor 4 Signaling in Mice

Kristina Schoonjans, Johan Auwerx, Xu Wang

The plasma membrane-bound G protein-coupled bile acid receptor (TGR5) displays varied levels of expression in different tissues. TGR5-induced liver protection has been demonstrated during several liver diseases, except during ischemia/reperfusion injury (I ...

Clobetasol propionate causes immunosuppression in zebrafish (Danio rerio) at environmentally relevant concentrations

Kristin Schirmer, Anita Orsolya Hidasi

Synthetic glucocorticoids (GCs) are potential endocrine disrupting compounds that have been detected in the aquatic environment around the world in the low ng/L (nanomolar) range. GCs are used as immunosuppressants in medicine. It is of high interest wheth ...

Neuroplastic Changes Following Brain Ischemia and their Contribution to Stroke Recovery: Novel Approaches in Neurorehabilitation

Silvestro Micera, Stefano Lai

Ischemic damage to the brain triggers substantial reorganization of spared areas and pathways, which is associated with limited, spontaneous restoration of function. A better understanding of this plastic remodeling is crucial to develop more effective str ...

Inflammatory arthritis and systemic bone loss are attenuated by gastrointestinal helminth parasites

Manuel Kulagin, Nicola Harris, Mario Michael Zaiss

Infections with different helminth species have been observed to ameliorate a variety of chronic inflammatory diseases. Herein, we show that the natural murine helminth species, Heligmosomoides polygyrus bakeri (Hp) is capable of attenuating disease severi ...

Detection of environmental glucocorticoids and investigation of their effects using the zebrafish embryo as a model

Anita Orsolya Hidasi

Synthetic glucocorticoids (GCs) are widely used anti-inflammatory drugs. They mimic cortisol, the natural stress hormone in humans and in fish. Cortisol binds and activates the glucocorticoid receptor (GR), which regulates genes governing development, immu ...
