Pepducin-mediated cardioprotection via β-arrestin-biased β2-adrenergic receptor-specific signaling [PDF]
Reperfusion as a therapeutic intervention for acute myocardial infarction-induced cardiac injury itself induces further cardiomyocyte death. β-arrestin (βarr)-biased β-adrenergic receptor (βAR) activation promotes survival signaling responses in vitro ...

Identification and light-dependent translocation of a cone-specific antigen, cone arrestin, recognized by monoclonal antibody 7G6 [PDF]
PURPOSE: To elucidate the antigen recognized by monoclonal antibody (mAb) 7G6, a widely used cone-specific marker. METHODS: 7G6 immunocytochemistry was performed on sections of human, primate, and bovine retina.

β-Arrestins and Cell Signaling [PDF]
Upon their discovery, β-arrestins 1 and 2 were named for their capacity to sterically hinder the G protein coupling of agonist-activated seven-transmembrane receptors, ultimately resulting in receptor desensitization. Surprisingly, recent evidence shows that β-arrestins can also function to activate signaling cascades independently of G protein ...

Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

Light-Dependent Translocation of Arrestin in the Absence of Rhodopsin Phosphorylation and Transducin Signaling [PDF]
Visual arrestin plays a crucial role in the termination of the light response in vertebrate photoreceptors by binding selectively to light-activated, phosphorylated rhodopsin.

Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...

Distinct and shared roles of β-arrestin-1 and β-arrestin-2 on the regulation of C3a receptor signaling in human mast cells. [PDF]
The complement component C3a induces degranulation in human mast cells via the activation of cell surface G protein coupled receptors (GPCR; C3aR).

Measuring ligand efficacy at the mu-opioid receptor using a conformational biosensor. [PDF]
The intrinsic efficacy of orthosteric ligands acting at G-protein-coupled receptors (GPCRs) reflects their ability to stabilize active receptor states (R*) and is a major determinant of their physiological effects.

Molecular profiling of resident and infiltrating mononuclear phagocytes during rapid adult retinal degeneration using single-cell RNA sequencing. [PDF]
Neuroinflammation commonly accompanies neurodegeneration, but the specific roles of resident and infiltrating immune cells during degeneration remains controversial.

Preclinical models for evaluating psychedelics in the treatment of major depressive disorder
Psychedelic drugs have seen a resurgence in interest as a next generation of psychiatric medicines with potential as rapid‐acting antidepressants (RAADs). Despite promising early clinical trials, the mechanisms which underlie the effects of psychedelics are poorly understood.
