Large number of receptors may reduce cellular response time variation [PDF]
Cells often have tens of thousands of receptors, even though only a few activated receptors can trigger full cellular responses. Reasons for the overabundance of receptors remain unclear. We suggest that, in certain conditions, the large number of receptors results in a competition among receptors to be the first to activate the cell.

Ligand-guided homology modeling drives identification of novel histamine H3 receptor ligands [PDF]
In this study, we report a ligand-guided homology modeling approach allowing the analysis of relevant binding site residue conformations and the identification of two novel histamine H3 receptor ligands with binding affinity in the nanomolar range.

Mast cell clones: a model for the analysis of cellular maturation. [PDF]
Cloned mouse mast cells resemble, by ultrastructure, immature mast cells observed in vivo. These mast cell clones can be grown in the absence of any other cells, facilitating direct investigations of their biochemistry and function.

Histamine and migraine revisited: mechanisms and possible drug targets
Objective To review the existing literature on histamine and migraine with a focus on the molecule, its receptors, its use in inducing migraine, and antihistamines in the treatment of migraine. Background Histamine has been known to cause a vascular type

The role of endocardial endothelium in the effect of histamine on myocardial contractions of histamine H1 and H2 receptor blockade [PDF]
Endocardial endothelium (EE) is a barrier which controls the passage of macromolecules and fluids between the blood and the adjacent miocardial interstitium. At the same time it is the place of synthesis of numerous endothelial mediators. Histamine as an

Efficacy of the Multi-Target Compound E153 in Relieving Pain and Pruritus of Different Origins
Itch and pain are closely related but distinct sensations that share largely overlapping mediators and receptors. We hypothesized that the novel, multi-target compound E153 has the potential to attenuate pain and pruritus of different origins.

Neuropharmacological targets for drug action in vestibular sensory pathways [PDF]
The use of pharmacological agents is often the preferred approach to the management of vestibular dysfunction. In the vestibular sensory pathways, the sensory neuroepithelia are thought to be influenced by a diverse number of neuroactive substances that ...

Delineating the role of histamine-1- and -4-receptors in a mouse model of Th2-dependent antigen-specific skin inflammation. [PDF]
BACKGROUND: Histamine drives pruritus in allergic skin diseases which clinically constitutes a most disruptive symptom. Skin pathology in allergic skin diseases is crucially influenced by different T-helper subsets. However, the contribution of different

Algebraic study of receptor-ligand systems: a dose-response analysis [PDF]
The study of a receptor-ligand system generally relies on the analysis of its dose-response (or concentration-effect) curve, which quantifies the relation between ligand concentration and the biological effect (or cellular response) induced when binding its specific cell surface receptor.
