Summary: This article investigates the role of microbial communities and their associated bioactive compounds in inflammatory bowel diseases (IBD). It systematically identifies potentially bioactive protein families involved in gut inflammation during IBD and validates their bioactivity using a combination of metagenomics, metatranscriptomics, and metaproteomics. The results provide candidate microbial proteins that interact with the host immune system in IBD, expanding our understanding of potentially bioactive gene products in chronic diseases.

Summary: Engineered probiotic i-ROBOT has been developed to noninvasively monitor and record the occurrence and progression of inflammatory bowel disease (IBD) in real time, and release treatments based on disease-associated biomarkers. It provides a heritable genomic DNA sequence and a colorimetric signal by activating a base-editing system in response to the inflammatory marker thiosulfate. In experiments with mice, i-ROBOT effectively ameliorated colitis and showed potential for the treatment of gastrointestinal and metabolic disorders.

Summary: The probiotic characteristics of Lacticaseibacillus rhamnosus grx10 were investigated through genotype and phenotype analysis in this study. In vitro experiments showed that grx10 exhibited excellent resistance to ambient stresses, bacteriostatic activity, and adhesion ability, indicating its potential as a probiotic. Complete genome sequencing revealed the genetic information and genes associated with probiotic characteristics, as well as the prediction of genes involved in extracellular proteins and secretory pathways. Among the secreted proteins, p40 and p75 were found to promote intestinal barrier integrity, with an abundance of 0.36% and 0.20% in the fermented supernatant of grx10. This study highlights the potential of grx10 in protecting the intestinal barrier from a postbiotic perspective.

Summary: The potential probiotic Enterococcus faecalis KUMS-T48, isolated from an Iranian traditional dairy product, has been found to have anti-pathogenic, anti-inflammatory, and anti-proliferative properties against specific cancer cell lines. The strain showed strong effects against Bacillus subtilis and Listeria monocytogenes, moderate effect against Yersinia enterocolitica, and weak effects against Klebsiella pneumoniae and Escherichia coli. Additionally, the cell-free supernatant of E. faecalis KUMS-T48 inhibited the proliferation of cancer cells in a similar manner to Taxol, but without affecting normal cell lines. The supernatant was found to have a proteinaceous nature and induced apoptosis-based cytotoxic mechanism through the regulation of specific genes.

Summary: Inflammatory bowel diseases (IBDs) are associated with elevated levels of reactive oxygen species (ROS) and dysregulated gut microbiota. In this study, researchers developed ROS-scavenging nanoparticles (HPN) to effectively scavenge ROS. They targeted the colon tissue by conjugating HPN to modified probiotic Escherichia coli Nissle 1917 (EcN). To enhance the efficacy of bacteriotherapy, the EcN cells were encapsulated with a poly-norepinephrine (NE) layer for protection against environmental assaults and prolonged retention in the intestine. The HPN-NE-EcN treatment showed enhanced efficacy in colitis models and increased abundance and diversity of gut microbiota.

Summary: The study evaluated variations in salivary microbiota in IBD patients and healthy controls, finding dysbiosis in IBD characterized by changes in microbiota biodiversity and composition, and significant increases in certain oral biofilm-forming bacteria. Levels of inflammatory cytokines associated with IBD were also found to be elevated and correlated with specific bacteria, with functional variations identified in genetic information processing, carbohydrate metabolism, and protein processing in endoplasmic reticulum in IBD.

Summary: Cross-kingdom communication through non-coding RNAs, particularly exogenous miRNAs ingested through diet, has risen as a novel discovery. These miRNAs, considered unstable in the gastrointestinal tract, may resist conditions and exert regulatory effects after being transported in extracellular vesicles. Despite challenges, extracellular miRNAs show promise as potential therapeutic agents for future pharmacological development.

Summary: This study aimed to develop a comprehensive workflow to elucidate molecular features of artichoke pectic oligosaccharides (POS) contributing to high potential prebiotic activity. By optimizing the obtainment of artichoke POS and characterizing the oligosaccharide structures, the study proposed interaction mechanisms between POS and microbial glycosidases, as well as integrated chemical information in virtual simulations of colonic fermentation. The established structure-activity relationships could potentially help in the rational design of prebiotics and in clinical trials.

Summary: Patients diagnosed with acute leukemia often have a weakened immune system, making infections a major concern. This study used shotgun metagenomics to screen the gut of recovered leukemia patients for ESBL- and/or carbapenemase-producing Enterobacterales. The results showed no presence of these bacteria, indicating successful decolonization and positive implications for future clinical management. Further studies are needed to validate the utility of metagenomics in routine screening of multidrug-resistant bacteria in onco-hematological patients.

Summary: Arabinoxylan (AX) and arabinoxylo-oligosaccharides (AXOS) are prebiotics that promote beneficial species in the human gut, such as bifidobacteria. Bifidobacterium longum and B. longum subsp. longum have the highest capability to metabolize complex AX substrates, while B. longum subsp. infantis also possesses some machinery related to AXOS metabolization. A differential carbohydrate free medium (CFM) supplemented with AX and AXOS was developed to selectively isolate novel probiotic bifidobacteria that can metabolize structurally complex AX-derived prebiotics.
