Plasma diamine oxidase activity in asthmatic children [PDF]
Histamine plays an important role in the development of asthmatic symptoms. Diamine oxidase (DAO histaminase), which inactivates histamine, is located in the intestine and kidney and is released into plasma.

Testosterone as Diamine Oxidase Activity Regulator [PDF]
Diamine oxidase (DAO) is a key enzyme of the metabolism of polyamines. Its activity was assayed in homogenate of male immature rat liver and kidney. The androgens are important regulators of polyamines’ metabolism.

Histamine intolerance caused by Diamine Oxidase (DAO) deficiency – case report
Histamine is a biogenic amine, which occurs naturally in the human body. Histamine can be metabolised with Diamine Oxidase (DAO) Enzyme. It is estimated that in 1% of people, as a result of an imbalance between the supply and degradation of histamine, a ...

Advances in the Clinical Application of Histamine and Diamine Oxidase (DAO) Activity: A Review
The serum level of diamine oxidase (DAO) reflects the integrity and maturation of the small intestinal mucosa. This measure is important in diagnosing various diseases, including chronic urticaria tachyphylaxis, multiple organ dysfunction syndrome, preterm abortion, and migraine.

Is histamine intolerance a treatable subtype of fibromyalgia? evidence and clinical implications—narrative review [PDF]
BackgroundFibromyalgia affects 2%–8% of the global population with suboptimal treatment outcomes. Emerging evidence suggests histamine intolerance, mediated by diamine oxidase (DAO) deficiency, may contribute to fibromyalgia pathophysiology in specific ...

Mapping of the binding sites of human diamine oxidase (DAO) monoclonal antibodies. [PDF]
Recently we characterized five mouse monoclonal antibodies that allow the specific and sensitive detection of human diamine oxidase (DAO). To understand differences in binding characteristics and recognition of enzyme variants, we mapped the antibody binding sites.Fragments of human DAO were expressed as glutathione-S-transferase fusion proteins that ...
