Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Relationship Between Fecal Bile Acid Profile and Intestinal Microbiota in Patients With Chronic Radiation Enteritis

Journal of Digestive Diseases, EarlyView.
Patients with chronic radiation enteritis (CRE) demonstrate dysregulated bile acid (BA) metabolism, characterized by an increased proportion of primary BAs and a decreased proportion of secondary BAs. Moreover, the diversity of the intestinal microbiota is significantly reduced in individuals with CRE, and there is a bidirectional interaction between ...

Postbiotics and Nicotinamide Utilize Distinct Mechanisms to Improve Skin Barrier Integrity, Inflammation, and Keratinocyte Differentiation

Allergy, EarlyView.
Integrating skin barrier measurements with omics and machine learning, we found that postbiotics and NAM regulate skin homeostasis through distinct, strain‐ and dose‐dependent mechanisms. Postbiotics primarily modulate skin barrier function by promoting keratinocyte differentiation and suppressing inflammation.

Psychedelics, entactogens and psychoplastogens for depression and related disorders

British Journal of Pharmacology, EarlyView.
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N‐dimethyltryptamine, ayahuasca; non‐hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g.

Anti‐inflammatory effects of physical stimuli: The central role of networks in shaping the future of pharmacological research

British Journal of Pharmacology, EarlyView.
Addressing complexity in the study of life sciences through Systems Biology and Systems Medicine has been transformative, making Systems Pharmacology the next logical step. In this review, we focus on physical stimuli, whose potential in pharmacology has been neglected, despite demonstrated therapeutic properties.

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor‐like lectin

The FEBS Journal, EarlyView.
We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

Shikimate pathway disruption in yeast induces metabolite self‐assembly into toxic aggregates

The FEBS Journal, EarlyView.
In Saccharomyces cerevisiae, shikimate pathway disruption induces toxic metabolite assemblies. Deleting ARO4 plus phenylalanine (Phe) feeding causes Phenylalanine accumulation, lowers ARO3 activity, and triggers amyloid‐like fibril formation. Deleting ARO3 plus tyrosine (Tyr) feeding leads to Tyrosine buildup and similar fibril assembly.
