Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

open access: yesAllergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

open access: yesBritish Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

Effects of Common Food Additives Kappa‐, Iota‐ and Lambda‐Carrageenans on Intestinal Epithelial Cell Activation and Barrier Disruption

open access: yesClinical &Experimental Allergy, EarlyView.
Carrageenans, widely used food additives, disrupted intestinal epithelial integrity in a gut‐on‐a‐chip model. All types (κ‐, ɩ‐, λ‐) induced cytotoxicity, inflammation and tight junction (TJ) disruption, triggering TNF‐mediated immune responses. λ‐Carrageenan had the most severe effects, supporting the Epithelial Barrier Theory linking food additives ...

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

open access: yesThe FEBS Journal, EarlyView.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

Structural and thermodynamic analyses of a novel β‐1,2‐glucan binding mode in the ABC transporter solute‐binding protein Chy400_4166 from Chloroflexus aurantiacus

open access: yesThe FEBS Journal, EarlyView.
Cyclic β‐1,2‐glucan (CβG)‐associated solute‐binding protein of type I ABC transporter was originally identified in Chloroflexus aurantiacus, a phototrophic bacterium. Crystal structures in complex with CβGs revealed unique binding modes that are fundamentally distinct from that of the short β‐1,2‐glucooligosaccharides‐binding protein.
