Intestinal expression of diamine oxidase (DAO) and the relationship between blood DAO activity and haptoglobin concentration in diarrheal calves. [PDF]
The objectives of this study were (1) to confirm the expression of diamine oxidase (DAO) in the intestines of healthy calves immune-histologically and to clarify whether the expression of DAO in the intestines of calves with diarrhea differs from that of healthy animals, and (2) to clarify the relationship between DAO and intestinal inflammation using ...

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABA<sub>A</sub> Receptors That Modulate Dorsal Root Ganglia Neuron Excitability. [PDF]
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

Serum diamine oxidase (DAO) activity as a diagnostic test for histamine intolerance [PDF]
Background Histamine intolerance (HIT) is characterized by an imbalance between histamine intake and the capacity for histamine degradation. The main enzyme for metabolizing ingested histamine is diamine oxidase (DAO). Determining DAO activity in serum may be useful in diagnosing HIT.

Introduction: The amine oxidase copper-containing 1 (AOC1) gene encodes for the diamine oxidase (DAO) enzyme. DAO is an enzyme that catabolizes some molecules, including histamine, and is the degradative enzyme in the polyamine catabolic pathway that is ...

Role of diamine oxidase in the pathogenesis of chronic urticaria
Chronic urticaria is a polyetiological disease proceeding by various immunological and non-immunological (pseudo-allergic) mechanisms. Food intolerance is a distinct type of pseudo-allergies, manifesting, e.g., with histamine intolerance syndrome, caused

Degradation of histamine in tuna soup by diamine oxidase (DAO) [PDF]
Histamine is a biogenic amine, which can cause food poisoning when present at high concentrations (>500 ppm). In situations where the formation of histamine in food cannot be prevented through traditional methods such as refrigeration, diamine oxidase (DAO) enzyme may be a suitable method to reduce histamine concentration to safe levels.

Clinical and Mechanistic Association Between Intestinal Permeability and the Gut Microbiome in Cirrhosis: Role of Phascolarctobacterium. [PDF]
ABSTRACT Background In patients with liver cirrhosis, intestinal permeability and the composition of the gut microbiome are altered. Thus, the microbiome might be a therapeutic target for the treatment of both liver diseases and intestinal permeability.

Semicarbazide diminishes the signs of bleomycin-induced pulmonary fibrosis in rats [PDF]
The pathogenesis of pulmonary fibrosis (PF) is accompanied by extracellular matrix (ECM) deposition, oxidative stress, and inflammation progression, as well as hyperactivation of amine oxidases (AOs), which contribute to disease manifestation.

1-methylhistamine as a potential biomarker of food histamine intolerance. A pilot study
Efforts are currently being directed to identify a non-invasive marker that can serve as a solid and clinically irrefutable diagnostic criterion for histamine intolerance associated with diamine oxidase (DAO) deficiency.
