Involvement of Diamine Oxidase and Peroxidase in Insolubilization of the Extracellular Matrix: Implications for Pea Nodule Initiation by Rhizobium leguminosarum

Molecular Plant-Microbe Interactions, 2000
Rhizobium leguminosarum colonizes host cells and tissues through infection threads, which are tubular in-growths of the plant cell wall. Monoclonal antibody MAC265 recognizes a plant matrix glycoprotein (MGP) associated with the lumen of these infection ...

Diamine oxidase-gold labels histamine in human mast-cell granules: a new enzyme-affinity ultrastructural method.

, 1993
We developed a post-embedding ultrastructural enzyme affinity-gold technique to label histamine. Diamine oxidase (DAO)-gold complex was prepared and tested for specificity with routinely processed, Epon-embedded, histamine-rich human mast-cell granules ...

Association of diamine oxidase and histamine N-methyltransferase polymorphisms with presence of migraine in a group of Mexican mothers of children with allergies

Neurología (English Edition), 2017
Background: Low histamine metabolism has been suggested to play a role in the pathogenesis of allergy and migraine. We investigated the possible association between 2 single-nucleotide polymorphisms (SNP), C314T HNMT and C2029G DAO, and the presence and ...

Histamine Intolerance: Clinical Characterization and Determination of Serum Diamine Oxidase (Dao) in a Series of Cases and Controls

, 2020
Abstract Introduction. Histamine intolerance (HIT) is a pathology with an estimated prevalence of 1% in which there is an imbalance between the intake of histamine via the digestive tract and the body's ability to degrade it. This results in an excessive accumulation of histamine that determines the appearance of gastrointestinal, skin ...

Carboxymethyl starch: Chitosan monolithic matrices containing diamine oxidase and catalase for intestinal delivery

, 2012
The capacity of carboxymethyl starch (CMS):Chitosan monolithic tablets to protect diamine oxidase and/or catalase therapeutic enzymes against simulated gastric fluid (SGF) and to control their delivery in simulated intestinal fluid (SIF) was investigated.

Gut Microbiota and Biomarkers of Intestinal Barrier Damage in Cirrhosis

Microorganisms
Gut dysbiosis and subclinical intestinal damage are common in cirrhosis. The aim of this study was to examine the association of intestinal damage biomarkers (diamine oxidase [DAO], claudin 3, and intestinal fatty acid binding protein [I-FABP; FABP2 ...

Observational Study on the Effectiveness of a Diamine Oxidase (DAO) Supplement in a Sample of Consumers with Histaminosis

World Journal of Food Science and Technology
Introduction: Histamine intolerance (HIT) is a multisystem disorder characterized by the excessive accumulation of histamine in the body, primarily due to reduced activity of the diamine oxidase (DAO) enzyme. This condition leads to a range of clinical manifestations, including headaches, gastrointestinal symptoms, fatigue, joint pain, and skin rashes.

Circadian profiling reveals higher histamine plasma levels and lower diamine oxidase serum activities in 24% of patients with suspected histamine intolerance compared to food allergy and controls

, 2017
Histamine intolerance is thought to trigger manifold clinical symptoms after ingesting histamine-rich food due to reduced activity of diamine oxidase (DAO).

Serum diamine oxidase in the neonate

, 1986
Serum diamine oxidase (DAO) activities were measured in 9 pregnant women and in 33 neonates during the 1st week of life. The radiometric method was used. Very high values were found in the mothers (mean +/- SE: 720 +/- 143 pmol ml-1 h-1). Neonates showed
