efficacy of seven agonists to induce G protein, G protein-coupled receptor kinase 2 (GRK2), as well as arrestin3 binding to prestimulated M3 receptors to avoid differences in receptor phosphorylation influencing arrestin We measured substantial differences in the agonist efficacies to induce M3R-arrestin3 versus M3R-GRK2 G protein and GRK2 binding to M3R requires similar receptor conformations, whereas requirements for arrestin3 Read full article

Deficiency of β-arrestin2 alleviates apoptosis through GRP78-ATF6-CHOP signaling pathway in primary Sjögren's Sjögren's syndrome (pSS) remains unknown, and there is no ideal drug for the specific treatment of pSS. β-arrestin2 apoptosis, and the effect depended on the interaction between GRP78 and β-arrestin2. for β-arrestin2 depletion in the treatment of the human autoimmune disorder pSS.

2022 "Biased G protein-coupled receptor (GPCR) ligands, which preferentially activate G protein or β-arrestin implicated in the pathophysiology of Alzheimer's disease (AD), biased GPCR signaling is a largely unexplored area Our previous work demonstrated that GPR3-mediated β-arrestin signaling modulates amyloid-β (Aβ) generation determined that G protein-biased signaling reduces soluble Aβ levels and leads to a decrease in the area Collectively, these studies indicate that GPR3-mediated G protein and β-arrestin signaling produce discrete

August 2022 "Three classes of G-protein-coupled receptor (GPCR) partners - G proteins, GPCR kinases, and arrestins

Cell survival assay in β-arrestin Knockout HEK293 cells showed that the NF-α1/CPE-5-HTR1E-mediated protection against oxidative stress was β-arrestin-dependent. by forming numerous salt bridges and hydrogen bonds to ICL2 and ICL3, leading to activation of β-arrestin1 Thus, NF-α1/CPE uniquely interacts with serotonin receptor 5-HTR1E to activate the β-arrestin/ERK/CREB Read full article

Receptor Expression and Intracellular Signaling in B Cells Are Highly Dynamic during Collagen-Induced Arthritis In the past, treatment of arthritic B cells with a β2-adrenergic receptor (β2-ADR) agonist has been shown to attenuate arthritis. In this study, the expression and signaling of β2-ADR in B cells during collagen-induced arthritis (CIA increase in β-Arrestin 2 only at late stage of arthritis.
