Loss of biased signaling at a G protein-coupled receptor in overexpressed systems.

open access: yesPLoS ONE, 2023
G protein-coupled receptors (GPCRs) regulate cellular signaling pathways by coupling to two classes of transducers: heterotrimeric G proteins and β-arrestins.

Differential CCR7 Targeting in Dendritic Cells by Three Naturally Occurring CC-Chemokines [PDF]

open access: yes, 2016
The CCR7 ligands CCL19 and CCL21 are increasingly recognized as functionally different (biased). Using mature human dendritic cells (DCs), we show that CCL19 is more potent than CCL21 in inducing 3D chemotaxis.

Mortality risk stratification for Takotsubo syndrome: Evaluating CRP measurement alongside the InterTAK prognostic score

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1427-1436, April 2025.
Abstract Background and objectives Initially described as a benign acute cardiomyopathy, Takotsubo syndrome has been linked to elevated mortality rates. Emerging evidence suggests that unresolved myocardial inflammation may contribute to this adverse prognosis.

β-Arrestin-1 expression and epithelial-to-mesenchymal transition in laryngeal carcinoma

open access: yesThe International Journal of Biological Markers, 2019
Aim: The novel primary end-point of the present study was to ascertain β-arrestin-1 expression in a cohort of consecutive patients with laryngeal squamous cell carcinoma (LSCC) with information available on their cigarette-smoking habits. A secondary end-

Monitoring β-arrestin recruitment via β-lactamase enzyme fragment complementation: purification of peptide E as a low-affinity ligand for mammalian bombesin receptors. [PDF]

open access: yesPLoS ONE, 2015
Identification of cognate ligands for G protein-coupled receptors (GPCRs) provides a starting point for understanding novel regulatory mechanisms. Although GPCR ligands have typically been evaluated through the activation of heterotrimeric G proteins ...

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

The Endothelial CXCR Family in Vascular Health and Disease

open access: yesiNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

GPCR kinase knockout cells reveal the impact of individual GRKs on arrestin binding and GPCR regulation

open access: yesNature Communications, 2022
GPCR kinases (GRKs) regulate GPCR interactions and thus functions. Here, the authors report a comprehensive panel of GRK knockout cells, used to assess the GRK-specific β-arrestin recruitment. Selective engagement of GRKs induces distinct GPCR–β-arrestin

Individual phosphorylation sites at the C-terminus of the apelin receptor play different roles in signal transduction

open access: yesRedox Biology, 2020
The apelin and Elabela proteins constitute a spatiotemporal double-ligand system that controls apelin receptor (APJ) signal transduction. Phosphorylation of multiple sites within the C-terminus of APJ is essential for the recruitment of β-arrestins.
