Expression of histamine receptors and effect of histamine in the rat carotid body chemoafferent pathway

, 2006
Chemosensory information from peripheral arterial oxygen sensors in the carotid body is relayed by petrosal ganglion neurons to the respiratory networks in the medulla oblongata.

Molecular Determinant Underlying Selective Coupling of Primary G‐Protein by Class A GPCRs

Advanced Science
G‐protein‐coupled receptors (GPCRs) transmit downstream signals predominantly via G‐protein pathways. However, the conformational basis of selective coupling of primary G‐protein remains elusive.

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.

Blockade of Cardiac Histamine Receptors by Promethazine

, 1974
The inotropic and chronotropic effects of histamine on the isolated perfused guinea pig heart were antagonized by promethazine over a concentration range 4 × 10−6 – 16 × 10−6 M.

Astrocytes serve as integrative hubs regulating sleep and arousal.

PLoS Biology
Astrocytes help control sleep and arousal. A new study in PLOS Biology shows that a wake-promoting signal called histamine affects how astrocytes respond to and modulate other brain signals and reduces time spent awake through astroglial histamine-1 ...

Identification of histamine receptors in the canine gastrointestinal tract

, 2016
The role of histamine in chronic gastrointestinal diseases has been increasingly recognized in humans, but the role of histamine in the canine gastrointestinal tract has not been thoroughly investigated.

Histamine receptors in rabbit atria

, 1979
In order to characterize the types of histamine receptors (H₁ or H₂) in rabbit atria, isolated atrial preparations were exposed to selective histamine receptor agonists, alone and in the presence of selective histamine receptor antagonists.
