Mechanism and function of histamine-sodium cotransport by astroglial cells

There is a saturable and high affinity uptake system for histamine in astroglial cells. The uptake is metabolically driven, sodium dependent and electrogenic. We consider the functional significance of these f...

Evidence for a regulatory role of a phosphorylation-dephosphorylation cycle in hypothalamic and lung histidine decarboxylase (HisDC) activity

To investigate the modulation of histidine decarboxylase (HisDC) activity by the degree of phosphorylation of a modulatory (or enzyme) protein, HisDC was partially purified from the cytosol of the hypothalamus...

Characterization of potassium channels in mast cell plasma membranes: Their possible existence and involvement in potassium-evoked histamine release

The effects of three K⁺-channel blockers, quinine, quinidine and sparteine on K⁺-evoked histamine (HA) release have been investigated. KCl (150 mM) initiated 40–55% release of HA from rat peritoneal mast cells in...

Contribution of glial cells to histamine inactivation

dl-α-aminoadipic acid (dl-αAA), a selective gliotoxic agent produced significant reductions in histamine-N-methyl-transferase (HNMT) and monoamine oxidase-B (MAO-B) activities and an enhancement in histamine (HA...

The effect of a new antihistamine drug, Loderix^® (EGIS-2062), on stimulus-evoked histamine release from rat peritoneal mast cells

The ability of a new, non-sedative antihistamine drug, Loderix^® (EGIS-2062), to inhibit stimulusevoked histamine release from rat peritoneal mast cells has been investigated and compared with that of ketotifen (Z...

Potassium-induced histamine release from mast cells and its inhibition by ketotifen

Potassium chloride induced a dose-dependent release of histamine from rat peritoneal mast cells at concentrations from 5 to 150 mM in the absence of extracellular Ca²⁺. Potassium concentrations greater than 150 m

Stimulation of hypothalamic histidine decarboxylase by calcium-calmodulin and protein kinase (cAMP-dependent) inhibitor

Stimulatory effects of Ca²⁺−CaM^* and PKI on partially purified hypothalamic HD (10 fold purification) have been shown under conditions involving inhibition of the enzyme by cAMP-induced phosphorylation and under ...

Evidence for the role of cAMP-dependent protein kinase in the down-regulation of hypothalamic HD: Reversal of cAMP-(ATP) induced inhibition of HD activity by the ‘Walsh’ inhibitor of cAMP-dependent protein kinase and by cyclic GMP

Under the total blockade of PDE¹ and the presence of endogeneous ATP and MgCl₂, the inhibitory effect of cAMP on HD activity could be demonstrated as low as 8.7×10⁻⁸ M concentration in a 20,000 g supernatant of a...
