Histamine and tumor necrosis factor alpha (TNF-alpha) can each contribute to the pathogenesis of allergic reactions and chronic inflammatory diseases. We now report the effect of histamine on gene expression and total cellular synthesis of TNF-alpha. Lipopolysaccharide (LPS)-induced synthesis of TNF-alpha in peripheral blood mononuclear cells (PBMC) from 18 healthy donors was suppressed by hist...

A key role for histamine in the physiological control of gastric acid secretion was established with the advent of the histamine H2-receptor antagonists which have in vivo been shown to inhibit virtually all forms of basal and stimulated secretion.' These data can be seen to support the common mediator hypothesis championed in the last three decades by Code2 3 and which states that secretory st...

The eye is a target organ for the action of several topical or systemic drugs. The aim of the present study is to analyze the differences in reactivity between the iris and conjunctiva vessels after the topical administration of histamine and histamine receptor blockers respectively. Using a novel non-invasive technique for the quantification of the vascular diameters in the eye vessels, the re...

We examined the effects of histamine and its agonists on the expression of the c-fos and c-myc proto-oncogenes at the transcriptional and translational levels in the human promonocytic U937 cell line. Histamine transiently increased cAMP and c-fos expression through H2 receptors. Dibutyryl cAMP also increased c-fos mRNA and protein, and levels remained elevated even after 12 hr of treatment. Do...

e have known about histamine receptors in the heart for any years (1). The human H1and H2-histamine recepors were cloned and characterized in the early 1990s (2,3), ollowed closely by the human H3and H4-histamine eceptors several years later (4,5). Histamine is a natural ody constituent that is found throughout the body, espeially the central nervous system, mast cells, gastric mucosa arietal c...
