Abstract Histamine [2-(4-imidazolyl)ethylamine, HA] is an endogenous biogenic amine synthesized in and released from several kinds of cells, and involved in many kinds of biological signalling (Uvnas 1991). Mast cells (a family of bone marrow-derived secretory cells) store much of the body’s HA in very high concentrations.

Histamine and Histamine Receptor Antagonists in Cancer Biology
Inflammation & Allergy - Drug Targets, 2010Histamine has been demonstrated to be involved in cell proliferation, embryonic development, and tumour growth. These various biological effects are mediated through the activation of specific histamine receptors (H1, H2, H3, and H4) that differ in their tissue expression patterns and functions.

Histamine H3-receptor isoforms
Inflammation Research, 2004Increasing 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, 1988The 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
2016In 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, 1991In 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, 1987The 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 ...
