[Role of therapeutics for allergic diseases in targeting histamine H1 receptor gene expression].
Histamine H(1) receptors are down-regulated as one step in receptor desensitization. Five phosphorylation sites of the H(1) receptor seem to play a key role in receptor down-regulation. In contrast, an increase in the H(1) receptor expression level following its mRNA elevation was found in the nasal mucosa in hypersensitivity model rats. Up-regulation of the H(1) receptor was induced by the direct stimulation of the H(1) receptor. H(1) receptor up-regulation was suppressed by pretreatment with antiallergic agents.
