Histamine enhances ATP-induced itching and responsiveness to ATP in keratinocytes

open access: yesJournal of Pharmacological Sciences, 2022
Mechanical stimulation of cultured keratinocytes and a living epidermis increases intracellular calcium ion concentrations ([Ca2+]i) in stimulated cells. This action propagates a Ca2+ wave to neighboring keratinocytes via ATP/P2Y2 receptors.

Targeting Histone H3K9 Methyltransferase G9a as a Potential Therapeutic Strategy for Neuropsychiatric Disorders

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Neuropsychiatric disorders present a multifaceted challenge, characterized by cognitive, social, and motor impairments with manifold underlying mechanisms. Recent attention has turned to epigenetic mechanisms, particularly histone lysine methyltransferases (HKMTs), such as G9a, in understanding fundamental pathogenesis.

Methamphetamine- and 3,4-Methylenedioxymethamphetamine–Induced Behavioral Changes in Histamine H3–Receptor Knockout Mice

open access: yesJournal of Pharmacological Sciences, 2009
Histamine H3 receptors inhibit the release of not only histamine itself, but also other neurotransmitters including dopamine. Previous papers have reported that histaminergic neurons inhibit psychostimulant-induced behavioral changes.

Accuracy of direct gradient sensing by cell-surface receptors [PDF]

open access: yesarXiv, 2009
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

Proteomic Profiling Informs Mechanisms of Esophageal Adenocarcinoma Inhibition by Cranberry Proanthocyanidins

open access: yesMolecular Nutrition &Food Research, EarlyView.
In this study we utilized proteomic profiling to investigate mechanisms linked to the cancer‐inhibitory effect of cranberry proanthocyanidins (CPACs) on reflux‐induced esophageal adenocarcinoma in a rat model. The results indicate that CPAC inhibits cancer through targeting multiple hallmarks of cancer known to be dysregulated in progression to ...

Serotonin as a Creativity Pump [PDF]

open access: yesarXiv
The location of Western Civilization defined nations in Europe and in the United States within the largest global pollen environments on the planet is proposed as a key factor leading to their success. Environments with dense pollen concentrations will cause large up and down changes in serum histamine directly causing reductions and increases in brain
