Stimulation of Histamine H1 Receptor Up-Regulates Histamine H1 Receptor Itself Through Activation of Receptor Gene Transcription

open access: yesJournal of Pharmacological Sciences, 2007
Histamine is a major mediator in allergy acting mainly through the histamine H1 receptor (H1R). Although H1R up-regulation has been suggested as an important step for induction of allergic symptoms, little is known about the regulation of H1R level. Here

Pitolisant Inhibits Alcohol Drinking and Improves Withdrawal Negative Affect Through Lateral Habenula Histaminergic Signaling in Mice

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Pitolisant, an FDA‐approved H3R antagonist, counteracts the rewarding and sedative effects of ethanol, reduces alcohol intake, and alleviates the negative affect during withdrawal. This might occur via the antagonism of presynaptic autoreceptors and heteroreceptors H3Rs in the lateral habenula, thereby activating the H2R/p‐CREB/BDNF signaling and ...
