Pathophysiology and emerging treatments for dermographic, cholinergic and cold urticaria

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
This review illustrates key proposed mast cell‐mediated activation pathways in dermographic, cholinergic and cold urticaria, highlighting IgE‐dependent and ‐independent mechanisms. These pathways are increasingly targeted by emerging drugs, aiming to interrupt mast cell activation and mediator release, offering more precise, mechanism‐based treatment ...

Electromechanical modelling and simulation of human‐induced pluripotent stem cell‐derived cardiomyocytes predict drug‐induced contractility effects

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.

Antigen depolarizes guinea pig bronchial parasympathetic ganglion neurons by activation of histamine H1 receptors

open access: yes, 1995
Studies were carried out to evaluate the mechanism by which neurotransmission through airway parasympathetic ganglia may be modulated during immediate hypersensitivity reactions.

Histamine Regulates Molecular Clock Oscillations in Human Retinal Pigment Epithelial Cells via H1 Receptors

open access: yesFrontiers in Endocrinology, 2018
Vertebrate eyes are known to contain circadian clocks, but their regulatory mechanisms remain largely unknown. To address this, we used a cell line from human retinal pigment epithelium (hRPE-YC) with stable coexpression of reporters for molecular clock ...

Inflammation induced by snake venoms optimizes envenomation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustrating mechanisms underlying direct vascular absorption and subsequent movement of venom toxins into the tissues consequent to snakebite. A, snakebite into prey deposits venom toxins into the tissue interstitium, with the venom then causing acute inflammation primarily in venules.

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

open access: yesMedicinal Research Reviews, Volume 46, Issue 4, Page 1173-1229, July 2026.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Activation of Microglia by Histamine and Substance P

open access: yesCellular Physiology and Biochemistry, 2014
Background: Activated microglia perform many of the immune effector functions typically associated with macrophages. However, the regulators involved in microglial activation are not well defined.

Psychedelics, entactogens and psychoplastogens for depression and related disorders

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 14, Page 3897-3919, July 2026.
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N‐dimethyltryptamine, ayahuasca; non‐hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g.

Involvement of H1 and H2 Receptors and Soluble Guanylate Cyclase in Histamine-Induced Relaxation of Rat Mesenteric Collecting Lymphatics

open access: yes, 2014
Objective: This study investigated the roles of the H1 and H2 histamine receptors, NO synthase, and sGC cyclase in histamine-induced modulation of rat mesenteric collecting lymphatic pumping.

Effects of administration of histamine and its H1, H2, and H3 receptor antagonists into the primary somatosensory cortex on inflammatory pain in rats [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2014
Objective(s): The present study investigated the effects of microinjection of histamine and histamine H1, H2, and H3 receptor antagonists, chlorpheniramine, ranitidine and thioperamide, respectively into the primary somatosensory cortex (PSC) on ...
