Clinical &Experimental Allergy, EarlyView.We provide the first evidence that pronounced release of DAO during anaphylaxis is restricted to patients with clonal mast cell disorder. This finding offers possible functional support for the reported association between KIT p.D816V and anaphylaxis severity.

Basal Serum Diamine Oxidase Levels as a Biomarker of Histamine Intolerance: A Retrospective Cohort Study [PDF]
, 2022 Background: Histamine Intolerance (HIT) is a multifaceted pseudoallergic disorder possibly due to defective histamine metabolism. Diamine oxidase (DAO) contributes to histamine degradation and can be measured in the serum.

European Journal of Immunology, Volume 56, Issue 2, February 2026.Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...

The Rate of Histamine Degradation by Diamine Oxidase Is Compromised by Other Biogenic Amines
Frontiers in Nutrition, 2022 Nowadays, certain uncertainties related to the onset of histamine adverse effects remain unsolved and still require further research. Questions still to be resolved include the wide range of doses at which dietary histamine may trigger symptoms of ...

N-acetyl glucosamine improves intestinal mucosal barrier function in rat
Bangladesh Journal of Pharmacology, 2012 Our study investigated the effect of N-acetylglucosamine (GlcNAc) on the intestinal mucosal barrier function in rats. Rats were randomly assigned into normal control group, diarrhea-predominant irritable bowel syndrome (IBS-D) group and GlcNAc group. IBS-

Prevalence of genetic diamine oxidase (DAO) deficiency in women with fibromyalgia in Spain
, 2022 Abstract Diamine oxidase (DAO) is the enzyme responsible for the metabolism of intestinal histamine. Single nucleotide polymorphisms (SNPs) of the AOC1 gene are associated with low enzymatic activity or functionality in the metabolism of histamine.

Advanced Science, Volume 13, Issue 4, 19 January 2026.This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide
