There is increasing evidence that histamine affects dendritic cell (DC) activation, maturation, and preference for Th1/Th2 differentiation. In this paper we report that histamine affects interleukin (IL)-12 and IL-6 production in an immature DC (iDC) line derived from murine spleen. Histamine treatment of iDC significantly increased the IL-12 p40 mRNA and protein levels compared to histamine untreated iDC. In the presence of tumor necrosis factor (TNF)-alpha histamine also increased IL-12 p40 and IL-6 production. However, histamine significantly decreased IL-12 p40 production by lipopolysaccharide (LPS)-stimulated DC in a concentration dependent manner. When expressions of histamine H1 (H1R) and H2 (H2R) receptors in DC were analyzed by RT-PCR, both receptors were down-regulated after LPS or TNF-alpha stimulation compared to unstimulated iDC. Histamine treatment significantly increased the expression of H2R mRNA in iDC and H1R mRNA in LPS-activated DC. However, histamine treatment decreased the expression of both histamine receptors in TNF-alpha-stimulated DC. Similar results were obtained by flow cytometry with FITC-conjugated histamine. These results demonstrate that histamine can regulate the expression of its own receptors and activate iDC, which may influence subsequent functional states of mature DC in a maturation signal-dependent manner. Consequently, histamine may contribute to an immune response outcome.

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans

D011968 Receptors, Histamine Cell-surface proteins that bind histamine and trigger intracellular changes influencing the behavior of cells. Histamine receptors are widespread in the central nervous system and in peripheral tissues. Three types have been recognized and designated H1, H2, and H3. They differ in pharmacology, distribution, and mode of action. Histamine Binding Sites,Histamine Receptors,Histamine Receptor,Binding Sites, Histamine,Receptor, Histamine,Sites, Histamine Binding
D002454 Cell Differentiation Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs. Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D003713 Dendritic Cells Specialized cells of the hematopoietic system that have branch-like extensions. They are found throughout the lymphatic system, and in non-lymphoid tissues such as SKIN and the epithelia of the intestinal, respiratory, and reproductive tracts. They trap and process ANTIGENS, and present them to T-CELLS, thereby stimulating CELL-MEDIATED IMMUNITY. They are different from the non-hematopoietic FOLLICULAR DENDRITIC CELLS, which have a similar morphology and immune system function, but with respect to humoral immunity (ANTIBODY PRODUCTION).

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
