Chick retinal pigment epithelium A new culture system for studying H2-histamine receptors [PDF]

, 1983
Histamine elevates the intracellular cyclic AMP levels in cultured embryonic chick retinal pigment epithelium. The half-maximal activity is 6 × 10−6 M. The effect of histamine is mediated by H2 receptors, i.e., inhibited by the H2 antagonist cimetidine ...

Effect of the Fexofenadine on the expression of HRH-1 and HRH-4 receptor in Peripheral Blood Mononuclear Cell isolated from children with diagnosed allergy – in vitro study Short communication

Journal of Pharmacy & Pharmaceutical Sciences, 2019
Purpose: Fexofenadine (FXF) is the active metabolite of terfenadine with selective peripheral H1 receptor antagonist activity. FXF is a third-generation antihistamine, non-sedating, rapid and very long acting used in symptoms associated with allergic ...

Functional characterisation of the novel histamine H(3) receptor agonist, VUF 5810, on the guinea-pig isolated ileum

, 2003
It is known that the activation of prejunctionally-located histamine H3 receptors down-regulates the exocytotic acetylcholine release from the myenteric plexus and thus produces a negative control on the intestinal motility [1].

Species differences in histamine receptors in the seminal vesicle

, 1981
Histamine and specific H1- and H2-receptor agonists and antagonists in conjunction with phentolamine and (or) reserpine pretreatment were used to characterize histamine receptor(s) in the seminal vesicle of rat and guinea pig.

Antihistamines: Beyond just allergy treatment

Vietnam Journal of Science, Technology and Engineering
Histamine and its receptors (H1R-H4R) are involved in several significant physiological processes and pathogenic conditions. Antihistamines, widely recognised as drugs for treating allergies, belong to the H1 antihistamine group, which targets H1R on ...
