Abstract
Among the top ten causes of death in the United States, Alzheimer's disease (AD) is the only one that cannot be cured, prevented, or even slowed down at present. Significant efforts have been exerted in generating model systems to delineate the mechanism as well as establishing platforms for drug screening. In this study, a promising candidate model utilizing primary mouse brain organotypic (MBO) cultures is reported. For the first time, we have demonstrated that the MBO cultures exhibit increased blood brain barrier (BBB) permeability as shown by IgG leakage into the brain parenchyma, astrocyte activation as evidenced by increased expression of glial fibrillary acidic protein (GFAP), and neuronal damage-response as suggested by increased vimentin-positive neurons occur upon histamine treatment. Identical responses-a breakdown of the BBB, astrocyte activation, and neuronal expression of vimentin-were then demonstrated in brains from AD patients compared to age-matched controls, consistent with other reports. Thus, the histamine-treated MBO culture system may provide a valuable tool in combating AD.

Abstract
The effects of histamine on the membrane potential and currents of human glioblastoma (GL-15) cells were investigated. In perforated whole cell configuration, short (3 s) applications of histamine (100 microM) hyperpolarized the membrane by activating a K(+)-selective current. The response involved the activation of the pyrilamine-sensitive H(1) receptor and Ca(2+) release from thapsigargin-sensitive intracellular stores. The histamine-activated current was insensitive to tetraethylammonium (3 mM), iberiotoxin (100 nM), and d-tubocurarine (100 microM) but was markedly inhibited by charybdotoxin (100 nM), clotrimazole (1 microM), and 1-[(2-chlorophenyl)diphenylmethyl]-1H-pyrazole (TRAM-34, 1 microM), a pharmacological profile congruent with the intermediate conductance Ca(2+)-activated K(+) (IK(Ca)) channel. Cell-attached recordings confirmed that histamine activated a K(+) channel with properties congruent with the IK(Ca) channel (voltage independence, 22 pS unitary conductance and slight inward rectification in symmetrical 140 mM K(+)). More prolonged histamine applications (2-3 min) often evoked a sustained IK(Ca) channel activity, which depended on a La(2+) (10 microM)-sensitive Ca(2+) influx. Intracellular Ca(2+) measurements revealed that the sustained IK(Ca) channel activity enhanced the histamine-induced Ca(2+) signal, most likely by a hyperpolarization-induced increase in the driving force for Ca(2+) influx. In virtually all cells examined we also observed the expression of the large conductance Ca(2+)-activated K(+) (BK(Ca)) channel, with a unitary conductance of ca. 230 pS in symmetrical 140 mM K(+), and a Ca(2+) dissociation constant [K(D(Ca))] of ca. 3 microM, at -40 mV. Notably in no instance was the BK(Ca) channel activated by histamine under physiological conditions. The most parsimonious explanation based on the different K(D(Ca)) for the two K(Ca) channels is provided.

Abstract
We have investigated the effects of histamine on the intracellular calcium concentration ([Ca2+]i) of cultured rat cerebellar astrocytes using fura-2-based Ca2+ imaging microscopy. Most of the cells responded to the application of histamine with an increase in [Ca2+]i which was antagonized by the H1 receptor blocker mepyramine. When histamine was applied for several minutes, the majority of the cells displayed a biphasic Ca2+ response consisting of an initial transient peak and a sustained component. In contrast to the initial transient [Ca2+]i response, the sustained, receptor-activated increase in [Ca2+]i was rapidly abolished by chelation of extracellular Ca2+ or addition of Ni2+, Mn2+, Co2+ and Zn2+, but was unaffected by nifedipine, an antagonist of L-type voltage-activated Ca2+ channels. These data indicate that the sustained increase in [Ca2+]i was dependent on Ca2+ influx. When intracellular Ca2+ stores were emptied by prolonged application of histamine in Ca2+-free conditions, Ca2+ re-addition after removal of the agonist did not lead to an 'overshoot' of [Ca2+]i indicative of store-operated Ca2+ influx. However, Ca2+ stores were refilled despite the absence of any substantial change in the fura-2 signal. Depletion of intracellular Ca2+ stores using cyclopiazonic acid in Ca2+-free saline and subsequent re-addition of Ca2+ to the saline resulted in an increase in [Ca2+]i that was significantly enhanced in the presence of histamine. The results suggest that besides capacitative mechanisms, a non-capacitative, voltage-independent pathway is involved in histamine-induced Ca2+ entry into cultured rat cerebellar astrocytes.

Abstract
The aim of this study was to investigate the effect of sodium butyrate on calcium mobilization. Histamine was found to stimulate a dose-dependent increase in intracellular calcium concentrations ([Ca2+]i) through H1 receptors, but this effect was attenuated in C6 cells pretreated with 1-5 mM sodium butyrate. Evidence is provided that release of Ca2+ from intracellular stores is decreased in a dose-dependent manner. Experiments with BAPTA that show lower levels of [Ca2+]i in cells pretreated with higher concentrations of sodium butyrate suggest that sodium butyrate also decreases Ca2+ influx. These results suggest that changes in Ca2+ mobilization are at least partially responsible for sodium butylate-induced C6 cell differentiation.

Abstract
We examined the changes in phospholipid metabolisms in sodium butyrate-treated C6 glioma cells. Treatment of 2.5 mM sodium butyrate for 24 h induced an increase in the activity of glutamine synthetase, suggesting that these cells were under differentiation. Similar treatment was associated with (i) increased arachidonic acid incorporation into phosphatidylcholine, and (ii) decreased arachidonic acid incorporation into phosphatidylinositol and (iii) phosphatidylethanolamine. These effects were subsequently investigated by examining the acylation process, de novo biosynthesis, and the agonist-stimulated phosphoinositides hydrolysis in these cells. Our results indicated that sodium butyrate stimulated the acylation of arachidonic acid into lysophosphatidylcholine, lysophosphatidylethanolamine, and lysophosphatidylinositol. The glycerol incorporation into these lipids was not affected, but the inositol incorporation into total chloroform extracts and Pl and phosphatidylinositol 4-phosphate was decreased in the sodium butyrate-treated cells. Moreover, the accumulation of the rapid histamine-stimulated phosphoinositide metabolites, i.e., inositol monophosphate, inositol diphosphate, and inositol triphosphate (IP3) was decreased in these cells. To elucidate whether the decreased inositol phosphates were due to a decrease in the phosphoinositides hydrolysis, we measured the transient IP3 production directly by a receptor-binding assay. Our results indicated that histamine-stimulated transient IP3 formations were decreased. Taken together, these results indicated that multiple changes by multiple mechanisms of phospholipid metabolisms were found in sodium butyrate-treated C6 glioma cells. The decreased IP3 formation and its subsequent action, i.e., Ca2+ mobilization, may play an early but pivotal role by which sodium butyrate induces C6 glioma cell differentiation.

Abstract
Much of our present knowledge of glial cell function stems from studies of glioma cell lines, both rodent (C6, C6 polyploid, and TR33B) and human (1321N1, 138MG, D384, R-111, T67, Tp-276MG, Tp-301MG, Tp-483MG, Tp-387MG, U-118MG, U-251MG, U-373MG, U-787MG, U-1242MG, and UC-11MG). New methods such as patch clamp and Ca2+ imaging have lead to rapid progress the last few years in our knowledge about glial cells, where an unexpected presence and diversity of receptors and ion channels have emerged. Basic mechanisms related to membrane potential and K+ transport and the presence of voltage gated ion channels (Na+, inwardly rectifying K+, Ca(2+)-activated K+, Ca2+, and Cl- channels) have been identified. Receptor function and intracellular signaling for glutamate, acetylcholine, histamine, serotonin, cathecolamines, and a large number of neuropeptides (bradykinin, cholecystokinin, endothelin, opioids, and tachykinins) have been characterized. Such studies are facilitated in cell lines which offer a more homogenous material than primary cultures. Although the expression of ion channels and receptors vary considerably between different cell lines and comparative studies are rare, a few differences (compared to astrocytes in primary culture) have been identified which may turn out to be characteristic for glioma cells. Future identification of specific markers for receptors on glial and glioma cells related to cell type and growth properties may have great potential in clinical diagnosis and therapy.

Abstract
Glial cells in vitro express at least two types (H1 and H2) of histamine receptors and three types (EP, FP, and TP) of prostanoid receptors. The receptors expressed by glial cells differ according to the cell type and source in the brain. Furthermore primary astrocytes of same type derived from the same brain region are composed of heterogeneous subpopulations expressing different subsets of receptors. Fura-2 based Ca2+ microscopy revealed that astrocyte processes are important sites for histamine-induced Ca2+ signalling. Histamine and prostanoid receptors on glial cells may play important roles in the actions of histamine and prostanoids in the central nervous system.

Abstract
In this study we report that substance P stimulated [3H]glycogen breakdown and elevation of intracellular Ca2+ concentration in the human astrocytoma cell line UC-11MG. Both effects were dose dependent, and completely blocked by CP-96,345 suggesting the involvement of an NK1 receptor. Our previous studies indicated that norepinephrine and histamine stimulate glycogenolysis via cAMP and Ca2+ respectively. Combined stimulation with substance P and norepinephrine or histamine resulted in additive effects suggesting that there is no interaction between these neurotransmitters in regulating glycogenolysis in these cells. These results confirm that UC-11MG cells are a useful model system to investigate the functional role of neurotransmitter receptors in astroglial cells.

Abstract
1. Histamine (1 mM) induced an accumulation of inositol monophosphate ([3H]-IP1) in the U373 MG human astrocytoma cell line which increased with time in the presence of 30 mM Li+. After a 30 min incubation period with 1 mM histamine [3H]-IP1 was the major product detected (84 +/- 1% of total [3H]-IPx) and was present at a level 11 (+/- 1) fold of basal accumulation. 2. Concentration-response curves for histamine-induced [3H]-IP1 accumulation in U373 MG cells (EC50 5.4 +/- 0.5 microM) were shifted to the right in a parallel fashion by mepyramine (slope of a Schild plot 0.99 +/- 0.08), yielding a Kd for mepyramine of 3.5 +/- 0.3 nM, consistent with the involvement of histamine H1-receptors. 3. The temelastine-sensitive binding of [3H]-mepyramine to a membrane fraction from U373 MG cells was hyperbolic and had a mean Kd of 2.5 +/- 1.0 nM. The maximum amount of temelastine-sensitive binding was 86 +/- 19 pmol g-1 membrane protein. 4. Carbachol also induced [3H]-IP1 accumulation in U373 MG cells, 2.8 (+/- 0.1) fold of basal with 1 mM carbachol, with an EC50 of 48 +/- 8 microM. Pirenzepine shifted carbachol concentration-response curves to the right (slope of Schild plot 0.89 +/- 0.07) giving a Kd for pirenzepine of 0.10 +/- 0.01 microM, suggesting that phosphoinositide hydrolysis in U373 MG cells is mediated by the M3-, rather than the M1-, muscarinic receptor subtype. 5. [3H]-IP1 accumulation induced by both 1 mM histamine and by 1 mM carbachol increased when the Ca2+ concentration of the medium was increased from 'zero' (no added Ca2+) to 0.3 mM. Histamine-stimulated [3H]-IP1 accumulation was further increased, although not so markedly, as the Ca2+ was raised to 4 mM. The same pattern was apparent with histamine-induced accumulations of [3H]-IP2 and [3H]-IP3. In contrast, [3H]-IPx accumulation in response to carbachol increased between 0.3 and 1.3 mM, but thereafter remained unchanged ([3H]-IP1) or declined ([3H]-IP2 and [3H]-IP3). 6. In HeLa cells, [3H]-IP1 accumulations induced by 1 mM histamine and 1 mM carbachol showed the same pattern of Ca2+ dependence and were independent of extracellular Ca2+ above 0.3 mM (histamine) or 1.3 mM (carbachol). The response to carbachol appeared to be mediated by an M3-muscarinic receptor (apparent Kd for pirenzepine 0.09 microM). 7. In cross-chopped slices of guinea-pig cerebral cortex and guinea-pig cerebellum, [3H]-IPI accumulation induced by 1 mM histamine in the presence of 10 mM Li+ increased as the extracellular Ca2+ was increased from 0.3 to 2.5 mM, but a further increase to 4 mM had no further effect. In contrast the response to histamine in rat cerebral cortex increased markedly between 1.3 and 4 mM Ca2+. Accumulations of [3H]-IP1 induced by carbachol in guinea-pig or rat cerebral cortical slices were not increased as extracellular Ca2+ was raised from 0.3 to 4 mM.8. Nimodipine (100 nM) and w-conotoxin (3 microM) had no significant effect on histamine-induced [3H]-IP1accumulation in rat cerebral cortical slices or in U373 MG cells. 9. We conclude that histamine-induced [3H]-IP1 accumulation in U373 MG cells does appear to have a component dependent on the extracellular Ca2+ concentration. The degree of Ca2+-dependence approaches that observed in guinea-pig cerebral cortex but is much less than in rat cerebral cortex.Whether U373 MG cells will be of use as a model system for the apparent Ca2+-entry component observed in guinea-pig or rat brain slices remains to be established.

Abstract
Astrocytes from a variety of sources, including the human UC-11MG astrocytoma line, express receptors for histamine on their plasma membranes, but the function of these receptors is largely unknown. Here we report studies on the effect of histamine on newly synthesized glycogen in the human astrocytoma-derived cell line, UC-11MG. We have found [3H]glycogen hydrolysis with a EC50 of 2 microM and a maximum effect of 30% at 300 microM histamine. The glycogenolytic effect of histamine was completely blocked by the H1 receptor antagonist, mepyramine, and was insensitive to the H2 receptor antagonist, cimetidine. Histamine-induced glycogenolysis was significantly reduced in the absence of extracellular Ca2+ and the residual response could be accounted for by Ca2+ released from intracellular stores. The Ca2+ ionophore, ionomycin, induced a similar concentration-dependent increase in both intracellular Ca2+ concentration and in glycogenolysis. These results suggest that one function of astrocytic histamine receptors in vivo may be the stimulation of glucose release from astrocytes, and that this process is mediated by increased intracellular free Ca2+. The glycogenolytic effect of histamine and other neurotransmitters in different systems, and the possible implication of astrocytic glycogenolysis in the pathophysiology of ischemia are discussed.
