Comorbid Alzheimer's Disease and Type 2 Diabetes Microbiota Shape Age‐Associated Gut–Brain Axis Profiles

Aging Cell, Volume 25, Issue 5, May 2026.
Fecal microbiota transplantation from elderly donors with Alzheimer's disease, type 2 diabetes, or both conditions into antibiotic‐treated mice revealed that comorbid microbiota produce the most severe dysbiosis and strongest suppression of hippocampal neurotrophic gene expression.

The Relationship among Tyrosine Decarboxylase and Agmatine Deiminase Pathways in Enterococcus faecalis

Frontiers in Microbiology, 2017
Enterococci are considered mainly responsible for the undesirable accumulation of the biogenic amines tyramine and putrescine in cheeses. The biosynthesis of tyramine and putrescine has been described as a species trait in Enterococcus faecalis. Tyramine

Genetic Differentiation in the SdhC Subunit Confers Intrinsic Resistance to SDHI Fungicides in Fusarium asiaticum

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
In Fusarium asiaticum, two homologous SdhC subunits (FaSdhC1/C2) regulate sensitivity to SDHI fungicides: deletion of FaSDHC1 decreases sensitivity, while deletion of FaSDHC2 increases it. Multiple mutations in ΔFaSDHC2 confer resistance to SDHI fungicides.

The MdICE1/MdFAMA‐MdTYDC Transcriptional Module Confers Cold Tolerance by Regulating Dopamine Metabolism in Apple

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3012-3031, May 2026.
ABSTRACT Low temperature is a critical abiotic stress that imposes major constraints on the sustainable development of the fruit tree industry. Although exogenous dopamine has been shown to enhance cold tolerance in plants, its molecular mechanisms in apple (Malus domestica) remain poorly understood.

A role for antizyme inhibitor 2 in the biosynthesis and content of serotonin and histamine in mouse mast cells [PDF]

, 2015
Polyamines (putrescine, spermidine and spermine; PAs) are essential for the majority of living cells. Antizymes and antizyme inhibitors are key regulatory proteins of PA levels by affecting ornithine decarboxylase and PA uptake.

Comparative study of the conformational lock, dissociative thermal inactivation and stability of Euphorbia latex and lentil seedling amine oxidases [PDF]

The thermal stability of copper/quinone containing amine oxidases from Euphorbia characias latex (ELAO) and lentil seedlings (LSAO) was measured in 100 mM potassium phosphate buffer (pH 7.0) following changes in absorbance at 292 nm. ELAO was shown to be

Putrescine-polysaccharide conjugate as transglutaminase substrates and their possible use in producing crosslinked films

, 2010
Putrescine (1,4-diaminobutane) was covalently linked to alginate and low-methoxyl pectin to synthesize new aminated polysaccharides. Both putrescine-pectin and -alginate conjugates, although the latter at higher concentrations, were found to be able to ...
