Analysis of histamine as a hair-cell transmitter in the lateral line of Xenopus laevis [PDF]

, 1989
The actions of histamine and histamine antagonists on afferent nerve activity were investigated in the lateral line of Xenopus laevis. Histamine (0.002-2.0 mM) had no effect on spontaneous activity or excitatory responses to water motion.

The effects of histaminergic agents in the nucleus accumbens of rats in the elevated plus-maze test of anxiety.

Iranian Journal of Psychiatry, 2010
Objective: The nucleus accumbens (NAc) receive histaminergic neurons from tuberomammillary nuclei. There are reports indicating that central histamine systems are involved in many physiological behavioral processes, including anxiety.

Disruption of histamine/H1R signaling pathway represses cardiac differentiation and maturation of human induced pluripotent stem cells

Stem Cell Research & Therapy, 2020
Background The efficiency and quality of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) are crucial for regenerative medicine, disease modeling, drug screening, and the study of the development events during cardiac specification.

Tools for clinical pharmacists to identify medications that can cause drug‐induced cognitive impairment: A systematic review

JACCP: JOURNAL OF THE AMERICAN COLLEGE OF CLINICAL PHARMACY, Volume 7, Issue 12, Page 1207-1227, December 2024.
Abstract Cognitive impairment affects around 19% of community‐dwelling older adults in the United States. Pharmacists can play a significant role in identifying and deprescribing cognitive‐impairing medications through cognitive‐focused medication reviews or as part of comprehensive medication management.

Functional G-Protein-Coupled Receptor (GPCR) Synthesis: The Pharmacological Analysis of Human Histamine H1 Receptor (HRH1) Synthesized by a Wheat Germ Cell-Free Protein Synthesis System Combined with Asolectin Glycerosomes

Frontiers in Pharmacology, 2018
G-protein-coupled receptors (GPCRs) are membrane proteins distributed on the cell surface, and they may be potential drug targets. However, synthesizing GPCRs in vitro can be challenging. Recently, some cell-free protein synthesis systems have been shown

Binding characteristics of the doxepin E/Z‐isomers to the histamine H1 receptor revealed by receptor‐bound ligand analysis and molecular dynamics study

Journal of Molecular Recognition, Volume 37, Issue 5, September 2024.
Abstract Doxepin is an antihistamine and tricyclic antidepressant that binds to the histamine H1 receptor (H1R) with high affinity. Doxepin is an 85:15 mixture of the E‐ and Z‐isomers. The Z‐isomer is well known to be more effective than the E‐isomer, whereas based on the crystal structure of the H1R/doxepin complex, the hydroxyl group of Thr1123.37 is

Assessing the anticholinergic cognitive burden classification of putative anticholinergic drugs using drug properties

British Journal of Clinical Pharmacology, Volume 90, Issue 9, Page 2236-2255, September 2024.
Aims This study evaluated the use of machine learning to leverage drug absorption, distribution, metabolism and excretion (ADME) data together with physicochemical and pharmacological data to develop a novel anticholinergic burden scale and compare its performance to previously published scales.

Discovery of a Small Molecule Activator of Slack (Kcnt1) Potassium Channels That Significantly Reduces Scratching in Mouse Models of Histamine‐Independent and Chronic Itch

Advanced Science, Volume 11, Issue 15, April 17, 2024.
The potassium channel Slack is highly expressed in sensory neurons that sense itch. In this study, several new compounds that activate Slack are developed. It is found that the lead molecule, compound 6, effectively inhibits scratching elicited by multiple pruritogens in mice establishing Slack activation as a novel pharmacological strategy for the ...

Brain Histamine Modulates the Antidepressant-Like Effect of the 3-Iodothyroacetic Acid (TA1)

Frontiers in Cellular Neuroscience, 2019
3-iodothyroacetic acid (TA1), an end metabolite of thyroid hormone, has been shown to produce behavioral effects in mice that are dependent on brain histamine.
