Histamine potentiates activation of native and recombinant N-methyl-d-aspartate receptors (NMDARs), but its mechanisms of action and physiological functions in the brain remain controversial. Using four different models, we have further investigated the histamine-induced potentiation of various NMDAR-mediated responses. In single

Histamine H3 receptor inverse agonists are known to enhance the activity of histaminergic neurons in brain and thereby promote vigilance and cognition. 1-{3-[3-(4-Chlorophenyl)propoxy]propyl}piperidine, hydrochloride (BF2.649) is a novel, potent, and selective nonimidazole inverse agonist at the recombinant human H3 receptor.

We previously suggested that therapeutic effects of betahistine in vestibular disorders result from its antagonist properties at histamine H(3) receptors (H(3)Rs). However, H(3)Rs exhibit constitutive activity, and most H(3)R antagonists act as inverse agonists. Here, we have investigated the effects

The modulation of histamine neuron activity by various non-competitive NMDA-receptor antagonists was evaluated by changes in tele-methylhistamine (t-MeHA) levels and histidine decarboxylase (hdc) mRNA expression induced in rodent brain. The NMDA open-channel blockers phencyclidine (PCP) and MK-801 enhanced t-MeHA levels
