Structural basis of arrestin-3 activation and signaling

Nature Communications, 2017
While arrestins are mainly associated with GPCR signaling, arrestin-3 can signal independently of receptor interaction. Here the authors present the structure of arrestin-3 bound to inositol hexakisphosphate (IP6) and propose a model for arrestin-3 ...

Minocycline and bone marrow–derived mononuclear cells as potential therapeutics for hereditary retinal degenerations

Acta Ophthalmologica, Volume 104, Issue 6, Page e671-e685, September 2026.
Abstract Purpose To assess in Royal College of Surgeons (RCS) rats if the combination of two previously documented neuroprotective strategies: minocycline administration and bone marrow–derived mononuclear cells (BM‐MNCs) intravitreal transplantation, offers enhanced neuroprotection compared with each treatment alone.

β-arrestin-2 is an essential regulator of pancreatic β-cell function under physiological and pathophysiological conditions

Nature Communications, 2017
Beta-arrestins have key roles in development and metabolic functions as euglycaemic control and insulin sentitivity. Here Zhuet al. show that beta-arrestin-2 regulates insulin secretion and glucose tolerance in mice by promoting CAMKII functions in beta ...

CCL19 and CCL21 Display Reciprocal Dependence on R209 in ECL2 of CCR7 for Receptor Activation, Relating to Differences in the Chemokine N‐Terminal Region

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 3, September 2026.
ABSTRACT CCL19 and CCL21 interact differentially with their shared receptor CCR7. A key amino acid important for CCL19‐mediated receptor activation is arginine 209 (R209) in extracellular loop 2 (ECL2) of CCR7. CCL21 activation of CCR7, in contrast, does not depend on R209.

Agonist‐specific conformational dynamics at the β2‐adrenoceptor dictate allosteric modulation of Gαs signalling and bronchodilation

British Journal of Pharmacology, Volume 183, Issue 17, Page 5315-5335, September 2026.
Abstract Background and Purpose β2‐adrenoceptor (β2AR) agonists are the cornerstone of asthma therapy and promote bronchodilation through Gαs signalling in airway smooth muscle (ASM), but their efficacy is limited by β‐arrestin‐mediated β2AR desensitization.

Arrestins in Host–Pathogen Interactions

, 2013
In the context of host-pathogen interaction, host cell receptors and signaling pathways are essential for both invading pathogens, which exploit them for their own profit, and the defending organism, which activates early mechanism of defense, known as innate immunity, to block the aggression.

Peripheral κ opioid receptor in pain and inflammation: From molecular signalling and gene expression to drug discovery

British Journal of Pharmacology, Volume 183, Issue 17, Page 5157-5189, September 2026.
The κ opioid receptor (κ receptor, KOR) is a G protein‐coupled receptor with well established roles in analgesia and immune modulation. Although historically studied primarily in the central nervous system (CNS), growing evidence indicates that κ signalling in peripheral tissues plays an important role in regulating pain, inflammation and immune ...

The chemokine receptor‐like fourth extracellular loop of the apelin receptor differentially regulates apelin and elabela binding and signalling

British Journal of Pharmacology, Volume 183, Issue 18, Page 5641-5656, September 2026.
Abstract Background and Purpose Apelin and Elabela are endogenous ligands of the apelin receptor (apelin receptor/APJ), a GPCR involved in cardiovascular regulation and body fluid homeostasis. The human receptor contains a conserved disulfide bridge linking the N‐terminal domain to extracellular loop 3 (ECL3) via Cys19 and Cys281, forming a structural ...

The Secret (Mitotic) Life of Clathrin

Traffic, Volume 27, Issue 3, September 2026.
A perspective on the function of clathrin at the mitotic spindle during cell division. ABSTRACT The discovery of clathrin was a foundational event in membrane traffic research. Its identification as the major protein component of the coat that surrounds endocytic vesicles kickstarted the biochemical and molecular characterization of endocytosis. During
