Histamine H3-receptor isoforms

Inflammation Research, 2004
Increasing evidence supports a role for HA as a neurotransmitter and neuromodulator in various brain functions, including emotion, cognition, and feeding. The recent cloning of the histamine H3 receptor allowed for the subsequent cloning of a variety of H3 receptor isoforms from different species as well as the H4 receptor.

Histamine H2-receptor antagonists

Baillière's Clinical Gastroenterology, 1988
The first histamine H2-receptor antagonists were developed in the early 1970s, and they have a dominant role in today's management of peptic ulceration. The original regimens using either cimetidine or ranitidine attempted to control acidity across the 24 hours, but more 'modern' regimens use a large single dose of the H2-blocker in the evening, which ...

Histamine and Histamine Receptors in Allergic Dermatitis

2016
In this chapter we will first introduce the pathophysiological process of several skin diseases including allergic dermatitis, a common skin disease, including chronic allergic contact dermatitis (CACD), and atopic dermatitis (AD). In CACD and AD patients, repeated skin exposure to antigens contributes to the development of chronic eczematous lesions ...

Histamine H2-Receptor Antagonists

Nursing Clinics of North America, 1991
In summary, histamine initiates acid secretion by stimulating the H2 subtype histamine receptor on parietal cells. Cimetidine, rantidine, famotidine, and nizantidine are histamine H2-receptor antagonists that block this action of histamine, reducing gastric acid output and concentration under both basal and stimulated conditions.

Histamine Receptors in the Lung

Allergy and Asthma Proceedings, 1987
The availability of specific histamine receptor antagonists has provided evidence that human airways have both H1 and H2 receptors. H1 receptors, which mediate bronchoconstriction, predominate. H1 receptor antagonism can produce significant bronchodilatation in some asthmatics, block bronchoconstriction induced by antigen and histamine inhalation ...

Cardiac histamine receptors.

Federation proceedings, 1976
Current evidence pertinent to the identification of cardiac histamine receptors in the guinea pig is reviewed. Pharmacological characterization has been aided by the use of selective agonists and antagonists for both types of histamine receptors. It appears that both H1 and H2 receptors mediate the cardiac effects of histamine.

Cardiac histamine receptors.

Advances in myocardiology, 1980
Histamine can produce inotropic and chronotropic responses in both guinea pig and rabbit heart. In the guinea pig the responses are mediated primarily through stimulation of H2 receptors with H1 receptors being found mainly in left atria. In the rabbit H1 receptors predominate; H2 receptors are found only in right atria and are partially responsible ...
