Studies of membrane fluidity and heart contractile force in Trypanosoma cruzi infected mice
Memorias do Instituto Oswaldo Cruz, 2004 In Chagas disease serious cardiac dysfunction can appear. We specifically studied the cardiac function by evaluating: ventricle contractile force and norepinephrine response, affinity and density of beta-adrenergic receptors, dynamic properties of ...

Functional selectivity of GPCR-directed drug action through location bias. [PDF]
, 2017 G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.

Antipsychotic-induced bone loss: the role of dopamine, serotonin and adrenergic receptor signalling
Frontiers in Cell and Developmental Biology, 2023 Antipsychotics are commonly used in treating psychiatric disorders. These medications primarily target dopamine the serotonin receptors, they have some affinity to adrenergic, histamine, glutamate and muscarinic receptors. There is clinical evidence that

Large number of receptors may reduce cellular response time variation [PDF]
Physical biology 10 (3), 035008, 2013, 2012 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.

High-fat diet induces protein kinase A and G-protein receptor kinase phosphorylation of β2 -adrenergic receptor and impairs cardiac adrenergic reserve in animal hearts. [PDF]
, 2017 Key pointsPatients with diabetes show a blunted cardiac inotropic response to β-adrenergic stimulation despite normal cardiac contractile reserve. Acute insulin stimulation impairs β-adrenergically induced contractile function in isolated cardiomyocytes ...

The role of spinal adrenergic receptors on the antinociception of ginsenosides in a rat postoperative pain model [PDF]
Korean Journal of Anesthesiology, 2013 BackgroundThe effect of spinal adrenergic and cholinergic receptors on the anti-nociceptive effect of intrathecal ginsenosides was determined in a rat postoperative pain model.MethodsCatheters were placed into the intrathecal space of male Sprague-Dawley

The effect of alpha-2 adrenergic receptors on memory retention deficit induced by rapid eye movement sleep deprivation [PDF]
Iranian Journal of Basic Medical Sciences, 2020 Objective(s): Evidence shows that sleep deprivation (SD) disrupts the formation of hippocampus-related memories. Moreover, α2 adrenergic receptors that are wildly expressed in the CA1 hippocampal region have a significant role in modulating both sleep ...

Algebraic study of receptor-ligand systems: a dose-response analysis [PDF]
arXiv, 2022 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.
