A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Regulatory elements of stx2 gene and the expression level of Shiga-like toxin 2 in Escherichia coli O157:H7

Journal of Microbiology, Immunology and Infection, 2018
Background/Purpose: Shiga-like toxin (Stx) is an important factor in the pathogenesis of Escherichia coli O157:H7 infection and is responsible for some severe complications. Stx2 is usually associated with hemolytic uremic syndrome in humans.

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

The FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization

The FEBS Journal, EarlyView.
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Shiga toxin purification, structure and function [PDF]

, 1991
Shiga toxin is a potent toxin produced by Shigella dysenteriae type 1 strains. The toxin has three biologicactivities-cytotoxicity, enterotoxicity,and neurotoxicity-and one known biochemical effect: inhibition of protein synthesis.

The Interplay of M1 Macrophages and Dental Pulp Stem Cells Promotes Angiogenesis Through IL‐8‐Dependent VEGF Regulation: An In Vitro Study

International Endodontic Journal, EarlyView.
ABSTRACT Background Dental pulp inflammation triggers immune responses involving macrophages and dental pulp stem cells (DPSCs), which interact to regulate angiogenesis essential for tissue repair. M1 pro‐inflammatory macrophages predominate early in pulpitis, and clarifying their angiogenic role is vital in identifying inflammatory regenerative ...

Food Safety and Nutritional Aspects of Plant‐Based Dairy and Meat Alternatives: A Review

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Plant‐based dairy and meat alternatives (PBDA and PBMA) offer sustainability benefits but also introduce chemical and microbiological hazards to the diet. Key concerns include emerging mycotoxins, heavy metals, process contaminants, and heat‐resistant spore‐forming bacteria.

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 800-828, July/August 2026.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.
