Blocking Histamine H1 Improves Learning and Mnemonic Dysfunction in Mice With Social Isolation Plus Repeated Methamphetamine Injection

Journal of Pharmacological Sciences, 2008
The aim of this study was to investigate the effects of histamine H1 and H3 antagonists on learning and mnemonic dysfunction in mice. Two H1 antagonists, pyrilamine and clozapine, and the prototypic H3 antagonist thioperamide were used to study the role ...

Histamine H1 Receptors in Neural Stem Cells Are Required for the Promotion of Neurogenesis Conferred by H3 Receptor Antagonism following Traumatic Brain Injury

Stem Cell Reports, 2019
Summary: The neurological recovery following traumatic brain injury (TBI) is limited, largely due to a deficiency in neurogenesis. The present study explores the effects of histamine H3 receptor (H3R) antagonism on TBI and mechanisms related to ...

The Histamine H4 Receptor: From Orphan to the Clinic

Frontiers in Pharmacology, 2015
The histamine H4 receptor (H4R) was first noted as a sequence in genomic databases that had features of a G-protein coupled receptor. This putative receptor was found to bind histamine consistent with its homology to other histamine receptors and thus ...
