Substance P-induced trafficking of beta-arrestins. The role of beta-arrestins in endocytosis of the neurokinin-1 receptor.

The Journal of biological chemistry, 1999
Agonist-induced redistribution of G-protein-coupled receptors (GPCRs) and beta-arrestins determines the subsequent cellular responsiveness to agonists and is important for signal transduction. We examined substance P (SP)-induced trafficking of beta-arrestin1 and the neurokinin-1 receptor (NK1R) in KNRK cells in real time using green fluorescent ...

Innovations in Obesity Treatment: Beyond Adipose Tissue Dysfunction

Obesity Reviews, EarlyView.
Obesity drives chronic inflammation, insulin resistance, type 2 diabetes, and cancer development through adipocyte dysfunction. Addressing this multisystemic disorder requires integrated strategies beyond diet and exercise, such as thermogenesis activation via menthol or capsinoids and appetite control through GLP‐1/GIP agonists and neuromodulation to ...

The Significance of cGAS‐STING Signaling in Response to Oncogenic Viruses

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT The cyclic GMP‐AMP synthase (cGAS)‐stimulator of interferon genes (STING) signaling pathway, as a key DNA sensor, plays a significant role in the regulation of innate immune responses. This pathway can be activated by sensing abnormal DNA, and is of great significance for resisting the invasion of pathogenic microorganisms and maintaining ...

Beta arrestin 1 is a key regulator of pulmonary vascular tone

Proceedings of the National Academy of Sciences
Pulmonary arterial hypertension (PAH) is a serious disorder, in which increased vascular tone is one of the critical hallmarks. Since beta arrestins (bArrs) have been shown to regulate smooth muscle tone in the airways, we investigated the function of bArr1 in the pulmonary vasculature.

Beta‐arrestin and vasomotor control in the spontaneously hypertensive rat

The FASEB Journal, 2009
We tested the hypothesis that spontaneously hypertensive rats (SHR) exhibit reduced desensitization of the neuropeptide Y (NPY) Y1 receptor (Y1R) leading to altered hindlimb vasomotor control. ?‐arrestin 2 ( ?‐arr) is a key regulatory protein involved in the desensitization of the Y1R (as

Sex and Chronic Stress Alter the Distribution of Corticotropin‐Releasing Factor Receptor in Rat Hippocampus Following Oxycodone Conditioned Place Preference

Synapse, Volume 80, Issue 5, September 2026.
Chronic stress modifies the effect of oxycodone conditioned place preference (Oxy CPP) on corticotropin releasing factor 1 (CRFR1) subcellular distributions in hippocampal subregions. These stress‐ and oxycodone‐induced changes in CRFR1 density may influence sex differences in hippocampal learning and memory processes both at baseline and following Oxy

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.

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 ...
