Bile acid 7α-dehydroxylating bacteria accelerate injury-induced mucosal healing in the colon

Kristina Schoonjans, Rizlan Bernier-Latmani, Alessia Perino, Hadrien Charles Edouard Demagny, Eduard Vico Oton, Colin Volet, Antoine Jalil

Host-microbiome communication is frequently perturbed in gut pathologies due to microbiome dysbiosis, leading to altered production of bacterial metabolites. Among these, 7 alpha-dehydroxylated bile acids are notably diminished in inflammatory bowel diseas ...

Wars1 downregulation in hepatocytes induces mitochondrial stress and disrupts metabolic homeostasis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Hadrien Charles Edouard Demagny, Antoine Jalil

Several laboratories, including ours, have employed the Slc25a47tm1c(EUCOMM)Hmgu mouse model to investigate the role of SLC25A47, a hepatocyte-specific mitochondrial carrier, in regulating hepatic metabolism and systemic physiology. In this study, we revea ...

An antibiotic and a microorganism having bile acid 7α-dehydroxylation activity for treating non-infectious diseases

Kristina Schoonjans, Alessia Perino, Antoine Jalil

The present invention relates to one or more antibiotic(s) that disrupt(s) the microbial balance of the gut and a microorganism having bile acid 7α-dehydroxylation activity for use in the treatment of a non-infectious disease in a subject. ...

Asparagine protects pericentral hepatocytes during acute liver injury

Kristina Schoonjans, Alessia Perino, Hadrien Charles Edouard Demagny, Antoine Jalil, Ece Yildiz, Yu Sun, Nadia Bresciani

The nonessential amino acid asparagine can only be synthesized de novo by the enzymatic activity of asparagine synthetase (ASNS). While ASNS and asparagine have been implicated in the response to numerous metabolic stressors in cultured cells, the in vivo ...

Hepatic lipid overload triggers biliary epithelial cell activation via E2Fs

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Antoine Jalil, Giovanni Sorrentino, Ece Yildiz, Gaby El Alam

During severe or chronic hepatic injury, biliary epithelial cells (BECs) undergo rapid activation into proliferating progenitors, a crucial step required to establish a regenerative process known as ductular reaction (DR). While DR is a hallmark of chronic ...

Inhibition of mitophagy drives macrophage activation and antibacterial defense during sepsis

Johan Auwerx, Antoine Jalil

Mitochondria have emerged as key actors of innate and adaptive immunity. Mitophagy has a pivotal role in cell homeostasis, but its contribution to macrophage functions and host defense remains to be delineated. Here, we showed that lipopolysaccharide (LPS) ...
