A new house dust mite–driven and mast cell–activated model of asthma in the guinea pig
Abstract Background Animal models are extensively used to study underlying mechanisms in asthma. Guinea pigs share anatomical, pharmacological and physiological features with human airways and may enable the development of a pre‐clinical in vivo model that closely resembles asthma. Objectives To develop an asthma model in guinea pigs using the allergen

Abstract Neutrophil‐platelet interactions are responsible for thrombosis as well as inflammatory responses following acute myocardial infarction (AMI). While histamine has been shown to play a crucial role in many physiological and pathological processes, its effects on neutrophil‐platelet interactions in thromboinflammatory complications of AMI remain

Histamine, histamine receptors, and neuropathic pain relief
Histamine, acting via distinct histamine H1, H2, H3, and H4 receptors, regulates various physiological and pathological processes, including pain. In the last two decades, there has been a particular increase in evidence to support the involvement of H3 receptor and H4 receptor in the modulation of neuropathic pain, which remains challenging in terms ...

H(1)-Receptor activation triggers the endogenous nitric oxide signalling system in the rat submandibular gland. [PDF]
BACKGROUND: Histamine is released from mast cells by immunologic and non-immunologic stimuli during salivary gland inflammation, regulating salivary secretion. The receptor-secretory mechanism has not been studied in detail.

Histamine activates an intracellular Ca2+ signal in normal human lung fibroblast WI-38 cells
Histamine is an inflammatory mediator that can be released from mast cells to induce airway remodeling and cause persistent airflow limitation in asthma.

Vasopeptidase-activated latent ligands of the histamine receptor-1 [PDF]
Whether peptidases present in vascular cells can activate prodrugs active on vascular cells has been tested with 2 potential latent ligands of the histamine H1 receptor (H1R). First, a peptide consisting of the antihistamine cetirizine (CTZ) condensed at

The Effects of Histaminergic Agents in the Nucleus ccumbens of Rats in the Elevated Plus-Maze Test of Anxiety [PDF]
"n Objective: "n 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.
