Votucalis, a Novel Centrally Sparing Histamine-Binding Protein, Attenuates Histaminergic Itch and Neuropathic Pain in Mice

Frontiers in Pharmacology, 2022
Votucalis is a biologically active protein in tick (R. appendiculatus) saliva, which specifically binds histamine with high affinity and, therefore, has the potential to inhibit the host’s immunological responses at the feeding site. We hypothesized that

Influence of mirtazapine on salivary cortisol in depressed patients [PDF]

, 2003
Unlike other antidepressants, mirtazapine does not inhibit the reuptake of norepinephrine or serotonin but acts as an antagonist at presynaptic alpha(2)-receptors, at postsynaptic 5-HT2 and 5-HT3 receptors, and at histaminergic H1 receptors. Furthermore,

Histamine and Delirium: Current Opinion

Frontiers in Pharmacology, 2019
Delirium is a very common, but refractory clinical state, notably present in intensive care and in the growing aging community. It is characterized by fluctuating disturbances in a number of key behavioral features, namely cognition, mood, attention ...

Predictors of Response to Oral Medications and Low-Histamine Diet in Patients with Chronic Urticaria

Journal of Immunology Research, 2022
Background. Chronic urticaria (CU) is comprised of diverse phenotypes, and thus, a shift towards a precision medical approach is warranted in its management. Methods. This study enrolled 78 patients with CU.

Histamine stimulates the proliferation of small and large cholangiocytes by activation of both IP3/Ca2+ and cAMP-dependent signaling mechanisms [PDF]

, 2012
Although large cholangiocytes exert their functions by activation of cyclic adenosine 3',5'-monophosphate (cAMP), Ca(2+)-dependent signaling regulates the function of small cholangiocytes. Histamine interacts with four receptors, H1-H4HRs.

Novel chalcone-based fluorescent human histamine H 3 receptor ligands as pharmacological tools [PDF]

, 2012
Novel fluorescent chalcone-based ligands at human histamine H(3) receptors (hH(3)R) have been designed, synthesized, and characterized. Compounds described are non-imidazole analogs of ciproxifan with a tetralone motif.

Histamine H2 receptor negatively regulates oligodendrocyte differentiation in neonatal hypoxic-ischemic white matter injury

Journal of Experimental Medicine, 2020
This study demonstrated that histamine H2 receptor in oligodendrocytes negatively regulates its differentiation and remyelination in neonatal hypoxic-ischemic white matter injury through acting on the Wnt/β-catenin signaling pathway.

On the Mechanisms Underlying Histamine Induction of Gastric Mucosal Lesions in Rats With Partial Gastric Vascular Occlusion

Journal of Pharmacological Sciences, 2003
Although it is well known that histamine induces gastric mucosal lesions in laboratory animals, the fundamental mechanisms remain unclear. In order to further analyze the vascular mechanisms underlying histamine-induced lesions, a new model was developed

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 ...
