Histamine: A Mediator of Intestinal Disorders—A Review

open access: yesMetabolites, 2022
Within the gastrointestinal tract, histamine is present at relatively high concentrations, especially during inflammatory processes. Histamine is a biogenic amine with numerous effects on many cell types, mediated by the activation of its four different ...

The clinical meaning of histamine skin reactivity [PDF]

open access: yes, 2015
The definition of the “atopic state”, i.e. subjects presenting at least one skin wheal with a minimum diameter of 3 mm induced by an allergen skin-prick test (ASPT), is based on the assumption that wheal size depends entirely on the amount of histamine

The Histamine H4 Receptor: From Orphan to the Clinic

open access: yesFrontiers in Pharmacology, 2015
The histamine H4 receptor (H4R) was first noted as a sequence in genomic databases that had features of a G-protein coupled receptor. This putative receptor was found to bind histamine consistent with its homology to other histamine receptors and thus ...

Opposite effects of mepyramine on JNJ 7777120-induced amelioration of experimentally induced asthma in mice in sensitization and provocation. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND:Histamine is detected in high concentrations in the airways during an allergic asthma response. In a murine model of allergic asthma, JNJ 7777120, an antagonist at the histamine H(4) receptor, reduces asthmatic symptoms, while the histamine H ...

ANTI-INFLAMMATORY AND ANTI-ALLERGIC FEATURES OF ANTIBODIES TO HISTAMINE IN RELEASE-ACTIVE FORM: REVIEW OF EXPERIMENTAL AND CLINICAL RESEARCHES

open access: yesДетские инфекции (Москва), 2015
Preclinical and clinical studies of medical preparations (rengalin, ergoferon) containing release-active (P-A) antibodies to histamine confirmed their ability to provide anti-inflammatory and anti-allergic effect.

Hippocampal histamine receptors and conflictive exploration in the rat: studies using the elevated asymmetric plus-maze

open access: yesBrazilian Journal of Medical and Biological Research, 1997
The possible role of histamine receptors in the hippocampal formation on the exploratory motivation and emotionality of the rat was studied. An elevated asymmetric plus-maze composed of 4 different arms (no walls, single high wall, high and low walls and

A receptor-based analysis of local ecosystems in the human brain. [PDF]

open access: yes, 2017
BackgroundAs a complex system, the brain is a self-organizing entity that depends on local interactions among cells. Its regions (anatomically defined nuclei and areas) can be conceptualized as cellular ecosystems, but the similarity of their functional ...

Histamine Excites Rat Superior Vestibular Nuclear Neurons via Postsynaptic H1 and H2 Receptors in vitro

open access: yesNeurosignals, 2012
The superior vestibular nucleus (SVN), which holds a key position in vestibulo-ocular reflexes and nystagmus, receives direct hypothalamic histaminergic innervations.

Thyroxine-binding globulin: investigation of microheterogeneity [PDF]

open access: yes, 1981
Preparations of T4-binding globulin (TBG) from human serum was performed using only two affinity chromatography steps. Purity of the protein was demonstrated by a single band in overloaded disc and sodium dodecyl sulfate electrophoresis, equimolar ...

Functional Diversity of Histamine and Histamine Receptors

open access: yesJournal of Investigative Dermatology, 1992
In order to analyze the mechanisms by which a single biogenic amine like histamine is capable of inducing a wide variety of both physiologic and pathologic functions in various tissues/cells, histamine responses were dissected in detail from a biochemical and pharmacologic point of view.
