The conceptual foundations of innate immunity: Taking stock 30 years later

While largely neglected over decades during which adaptive immunity captured most of the attention, innate immune mechanisms have now become central to our understanding of immunology. Innate immunity provides the first barrier to infection in vertebrates, ...

An autologous antigen-agnostic dendritic cell therapy that forgoes antigen loading

Michele De Palma

We developed a method for generating dendritic cell progenitors (DCPs) from hematopoietic stem and progenitor cells isolated from bone marrow or blood. When engineered to express IL-12 and FLT3L, these DCPs reprogram the tumor microenvironment and elicit a ...

Genetic and dietary modulators of the inflammatory response in the gastrointestinal tract of the BXD mouse genetic reference population

Johan Auwerx, Kristina Schoonjans, Maroun Bou Sleiman, Alessia Perino, Xiaoxu Li, Jean-David Horacio Morel, Giorgia Benegiamo, Alexis Rapin, Alexis Maximilien Bachmann, Jonathan Allen Sulc, Johanne Gracia Anne Poisson

Inflammatory gut disorders, including inflammatory bowel disease (IBD), can be impacted by dietary, environmental, and genetic factors. While the incidence of IBD is increasing worldwide, we still lack a complete understanding of the gene-by-environment in ...

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

Alessio Mylonas

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 ...

CSF-contacting neurons respond to Streptococcus pneumoniae and promote host survival during central nervous system infection

Ludovic Pierre Gustave Keiser

The pathogenic bacterium Streptococcus pneumoniae (S. pneumoniae) can invade the cerebrospinal fluid (CSF) and cause meningitis with devastating consequences. Whether and how sensory cells in the central nervous system (CNS) become activated during bacteri ...

Basic Mechanisms of Immunometabolites in Shaping the Immune Response

Alexander Hooftman

Background Innate immune cells play a crucial role in responding to microbial infections, but their improper activation can also drive inflammatory disease. For this reason, their activation state is governed by a multitude of factors, including the metabo ...

Compartmentalized PGRP expression along the dipteran Bactrocera dorsalis gut forms a zone of protection for symbiotic bacteria

Bruno Lemaitre

All metazoan guts are subject to opposing pressures wherein the immune system must eliminate pathogens while tolerating the presence of symbiotic microbiota. The Imd pathway is an essential defense against invading pathogens in insect guts, but tolerance m ...

Expansion of T memory stem cells with superior anti-tumor immunity by Urolithin A-induced mitophagy

Pénélope Andreux

T memory stem cells (T-SCM) display increased self-renewal and prolonged survival capabilities, thus preventing T cell exhaustion and promoting effective anti-tumor T cell responses. T-SCM cells can be expanded by Urolithin A (UA), which is produced by the ...

Type 1 piliated uropathogenic Escherichia coli hijack the host immune response by binding to CD14

Kathrin Tomasek

A key attribute of persistent or recurring bacterial infections is the ability of the pathogen to evade the host's immune response. Many Enterobacteriaceae express type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and establish pe ...

Human commensal gut Proteobacteria withstand type VI secretion attacks through immunity protein-independent mechanisms

Thibault Géry L Sana, Melanie Blokesch, Sandrine Stutzmann, Candice Stoudmann, Leonardo Filipe Lemos Rocha, Nina Vesel, Nicolas Olmo Flaugnatti, Sandrine Natacha Isaac

While the major virulence factors for Vibrio cholerae, the cause of the devastating diarrheal disease cholera, have been extensively studied, the initial intestinal colonization of the bacterium is not well understood because non-human adult animals are re ...

An In Vivo Microfluidic Study of Bacterial Load Dynamics and Absorption in the C. elegans Intestine

Martinus Adela Maria Gijs, Thomas Lehnert, Vittorio Viri

Caenorhabditiselegans (C. elegans) has gained importance as a model for studying host-microbiota interactions and bacterial infections related to human pathogens. Assessing the fate of ingested bacteria in the worm's intestine is therefore of great interes ...

The role of immune effectors in controlling Drosophila-microbes interactions

Alice Marra

All live beings are in constant interaction with microorganisms that may be beneficial, deleterious or commensal. Insects in particular live in close contact with microorganisms. This is especially true for species, like the fruit fly Drosophila melanogast ...

Obesity-associated deficits in inhibitory control are phenocopied to mice through gut microbiota changes in one-carbon and aromatic amino acids metabolic pathways

Xavier Fernandez-Real Girona

Background Inhibitory control (IC) is critical to keep long-term goals in everyday life. Bidirectional relationships between IC deficits and obesity are behind unhealthy eating and physical exercise habits. ...

Identification of Allobaculum mucolyticum as a novel human intestinal mucin degrader

Guido Van Mierlo

The human gut microbiota plays a central role in intestinal health and disease. Yet, many of its bacterial constituents are functionally still largely unexplored. A crucial prerequisite for bacterial survival and proliferation is the creation and/or exploi ...

Unravelling the collateral damage of antibiotics on gut bacteria

Camille Véronique Bernadette Goemans

Antibiotics are used to fight pathogens but also target commensal bacteria, disturbing the composition of gut microbiota and causing dysbiosis and disease1. Despite this well-known collateral damage, the activity spectrum of different antibiotic classes on ...

Probiotics improve the neurometabolic profile of rats with chronic cholestatic liver disease

Cristina Ramona Cudalbu Moldovan, Veronika Rackayová, Jocelin Grosse, Emmanuelle Ines Flatt

Chronic liver disease leads to neuropsychiatric complications called hepatic encephalopathy (HE). Current treatments have some limitations in their efficacy and tolerability, emphasizing the need for alternative therapies. Modulation of gut bacterial flora ...

Dietary Fiber Is Essential to Maintain Intestinal Size, L-Cell Secretion, and Intestinal Integrity in Mice

Kristina Schoonjans

Dietary fiber has been linked to improved gut health, yet the mechanisms behind this association remain poorly understood. One proposed mechanism is through its influence on the secretion of gut hormones, including glucagon-like peptide-1 (GLP-1) and gluca ...
