Histamine acts as a modulatory neurotransmitter in the mammalian brain. It has an important role in the maintenance of wakefulness, and dysfunction in the histaminergic system has been linked to narcolepsy. Recent evidence suggests that aberrant histamine signalling in the

Despite the fact that food and diet are central issues, that concern patients with irritable bowel syndrome (IBS), the current understanding about the association between the intake of certain foods/food groups and the gastrointestinal (GI) symptom pattern, psychological symptoms, and

The novel once-daily β₂-agonist bronchodilator drug olodaterol has recently been shown to be effective in patients with allergic asthma for >24 hours. An increased cholinergic tone common to these patients may decrease the effectiveness of β₂-agonists. This could provide a

Epidermal hyperproliferation resulting in acanthosis is an important clinical observation in patients with atopic dermatitis, and its underlying mechanisms are not completely understood. Because increased levels of histamine are present in lesional skin, we investigated the effect of histamine, especially

Histamine is a biogenic amine that exerts its biological effects as a neurotransmitter and local mediator via four histamine receptor (HR) subtypes (H(x)Rs) - H(1)R, H(2)R, H(3)R, and H(4)R - belonging to the superfamily of G-protein-coupled receptors (GPCRs). All four
