β-arrestin-1 and β-arrestin-2 Restrain MRGPRX2-Triggered Degranulation and ERK1/2 Activation in Human Skin Mast Cells [PDF]
Frontiers in Allergy, 2022 As a novel receptor that efficiently elicits degranulation upon binding to one of its numerous ligands, MRGPRX2 has moved to the center of attention in mast cell (MC) research.

LSD-stimulated behaviors in mice require β-arrestin 2 but not β-arrestin 1 [PDF]
Scientific Reports, 2021 Recent evidence suggests that psychedelic drugs can exert beneficial effects on anxiety, depression, and ethanol and nicotine abuse in humans. However, their hallucinogenic side-effects often preclude their clinical use.

The β-blocker Nebivolol Is a GRK/β-arrestin biased agonist. [PDF]
PLoS ONE, 2013 Nebivolol, a third generation β-adrenoceptor (β-AR) antagonist (β-blocker), causes vasodilation by inducing nitric oxide (NO) production. The mechanism via which nebivolol induces NO production remains unknown, resulting in the genesis of much of the ...

Gq activity- and β-arrestin-1 scaffolding-mediated ADGRG2/CFTR coupling are required for male fertility [PDF]
eLife, 2018 Luminal fluid reabsorption plays a fundamental role in male fertility. We demonstrated that the ubiquitous GPCR signaling proteins Gq and β-arrestin-1 are essential for fluid reabsorption because they mediate coupling between an orphan receptor ADGRG2 ...

β-Arrestin 1 Differentially Modulates cAMP and ERK Pathways Downstream of the FSH Receptor [PDF]
Current Issues in Molecular BiologyThis study compared the gonadotropin gene sequences (LH and FSH subunits) of Cynomolgus and Rhesus monkeys and produced recombinant single-chain LHβ/α and FSHβ/α proteins. The α- and FSHβ-subunit sequences were identical between species, while LHβ showed

Regulation of MRGPRX2-mediated mast cell function by competence-stimulating peptide 1 and pro-adrenomedullin peptide [PDF]
Frontiers in ImmunologyIntroductionMas-related G protein-coupled receptor (GPCR)-X2 (MRGPRX2, mouse ortholog MrgprB2) is predominantly expressed in mast cells (MCs) and is activated by a wide range of cationic ligands such as bacterial quorum sensing molecules (QSMs) and pro ...
