Histamine receptors and the conjunctiva
Current Opinion in Allergy & Clinical Immunology, 2005The purpose of this review is to evaluate the effect of histamine on various receptors in the conjunctiva. A Medline search from 1980 was performed on the histamine receptor subtypes H1, H2 and H3 in the human conjunctiva.In the conjunctiva, histamine has been shown to induce various physiological and immunological changes through both H1 and H2 ...

Current Protocols in Pharmacology, 2001
AbstractThis unit describes three standard in vitro bioassays for studying histamine H1, H2 and H3 receptors in isolated intact tissues removed from the guinea pig. Both the H1 and H3 receptor assays are based on preparations of the ileum, whereas the spontaneously beating right atrium assay is used for the H2‐receptor.This unit describes three ...

Histamine Receptors in the Brain
Allergy and Asthma Proceedings, 1985In mammalian brain, neuronal histamine is likely to act as a neurotransmitter and is recognized by the two classes of histamine receptors (H1 and H2) previously characterized in peripheral organs. Cerebral H1 receptors can be selectively labeled by a tritiated antagonist mepyramine, in particulate fractions or in the living animal.

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, histamine receptors and their role in immune pathology
Clinical & Experimental Allergy, 2009SummaryThe important roles of histamine in body physiology and various pathologic events have been well established, whereas new and exciting findings are still being uncovered. Histamine is not only the major mediator of the acute inflammatory and immediate hypersensitivity responses, but has also been demonstrated to affect chronic inflammation and ...

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 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 ...

Histamine H3 Receptor Agonists
Mini-Reviews in Medicinal Chemistry, 2004The SAR of H3 ligands has been difficult to evaluate because of species differences, multiple isoforms and constitutive activity, among other complicating factors. A review is given of the sometimes-conflicting affinity, activity and efficacy data of H3 agonists that has been described in literature to date.

Histamine H4 receptor agonists
Bioorganic & Medicinal Chemistry Letters, 2010Since its discovery 10 years ago the histamine H(4) receptor (H(4)R) has attracted attention as a potential drug target, for instance, for the treatment of inflammatory and allergic diseases. Potent and selective ligands including agonists are required as pharmacological tools to study the role of the H(4)R in vitro and in vivo.

Histamine receptors are hot in immunopharmacology
European Journal of Pharmacology, 2006In addition to its well-characterized effects in the acute allergic inflammatory responses, histamine has been demonstrated to affect chronic inflammation and regulate several essential events in the immune response. Histamine can selectively recruit the major effector cells into tissue sites and affect their maturation, activation, polarization, and ...
