Abstract Background A drug designed for a specific target often interacts with multiple targets, either unintentionally or as part of its intended mechanism of action. This has been called pharmacological pleiotropy or polypharmacology. There are key endogenous ligands such as ATP, GABA and glutamate that act on various proteins in humans. Furthermore,

PAR1 Agonists Stimulate APC-Like Endothelial Cytoprotection and Confer Resistance to Thromboinflammatory Injury [PDF]
Stimulation of protease-activated receptor 1 (PAR1) on endothelium by activated protein C (APC) is protective in several animal models of disease, and APC has been used clinically in severe sepsis and wound healing.

Concepts of GPCR-controlled navigation in the immune system
G-protein-coupled receptor (GPCR) signaling is essential for the spatiotemporal control of leukocyte dynamics during immune responses. For efficient navigation through mammalian tissues, most leukocyte types express more than one GPCR on their surface ...

GIP in Cardiovascular and Kidney Disease: From Physiology to Pharmacology
ABSTRACT Aims To provide a comprehensive overview of the cardiovascular and renal effects of glucose‐dependent insulinotropic polypeptide (GIP) by integrating its physiological role with recent human trial data on tirzepatide, the first dual GIP and glucagon‐like peptide‐1 (GLP‐1) receptor agonist.

Behavioral Characterization of β-Arrestin 1 Knockout Mice in Anxiety-Like and Alcohol Behaviors
β-Arrestin 1 and 2 are highly expressed proteins involved in the desensitization of G protein-coupled receptor signaling which also regulate a variety of intracellular signaling pathways.

ABSTRACT Aim Glucagon is a key regulator of glucose and energy metabolism, yet the dose–response effects of glucagon on markers of metabolism in humans are not fully characterised. We investigated the dose‐dependent effects of glucagon on glucose metabolism, β‐cell secretion and markers of hepatic metabolism in healthy adults.

Arrestin-biased AT1R agonism induces acute catecholamine secretion through TRPC3 coupling
Angiotensin II type 1 receptor (AT1R)-mediated acute catecholamine release is modulated by β-arrestin. Here the authors show that β-arrestin-1 recruits the Ca2+channel TRPC3 and the PLCγ to the AT1R-β-arrestin complex, triggering G protein-independent ...

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...
