The H1 receptor is a histamine receptor belonging to the family of G-protein-coupled receptors. This receptor which is activated by the biogenic amine histamine is expressed throughout the body, specifically in smooth muscles, on vascular endothelial cells, in the heart, and in the central nervous system. The H1 receptor is linked to an intracellular G-protein (Gq) that activates phospholipase C and the phosphatidylinositol (PIP2) signaling pathway. Based on the number of drugs available on market it is the most clinically important molecular drug target.[1]

Role in inflammation

The production of prostaglandin E2 synthase induces the release of histamine from neurons, causing systemic vasodilation, along with increased cell permeability due to its action on H1 receptors.

Neurophysiology

Histamine H1 receptors are activated by endogenous histamine, which is released by neurons that have their cell bodies in the tuberomamillary nucleus of the hypothalamus. The histaminergic neurons of the tuberomammillary nucleus become active during the 'wake' cycle, firing at approximately 2 Hz; during slow wave sleep; this firing rate drops to approximately 0.5 Hz. Finally, during REM sleep, histaminergic neurons stop firing altogether. It has been reported that histaminergic neurons have the most wake-selective firing pattern of all known neuronal types.[2]

In the cortex, activation of H1 receptors leads to inhibition of cell membrane potassium channels. This depolarizes the neurons and increases the resistance of the neuronal cell membrane, bringing the cell closer to its firing threshold and increasing the excitatory voltage produced by a given excitatory current. H1 receptor antagonists, or antihistamines, produce drowsiness because they oppose this action, reducing neuronal excitation.[3]
