β-arrestin/connexin 43 complex anchors ERKs outside the nucleus: a pre-requisite for bisphosphonate anti-apoptotic effect mediated by CX43/ERK in osteocytes [PDF]

open access: yes, 2016
Bisphosphonates (BPs) anti-fracture ef cacy may be due in part to inhibition of osteocyte apoptosis. This effect requires opening of con- nexin (Cx) 43 hemichannels and phosphoryla- tion of the extracellular signal regulated kinases (ERKs).

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

open access: yesAdvanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Signaling bias of the protease-activated receptor-1 is dictated by distinct GRK5 and β-arrestin-2 determinants

open access: yesCell Reports
Summary: G protein-coupled receptors (GPCRs) exhibit signaling bias or preferential activation of heterotrimeric G proteins versus GPCR kinase (GRK)-mediated β-arrestin signaling.

Arrestin-biased AT1R agonism induces acute catecholamine secretion through TRPC3 coupling

open access: yesNature Communications, 2017
Angiotensin II type 1 receptor (AT1R)-mediated acute catecholamine release is modulated by β-arrestin. Here the authors show that β-arrestin-1 recruits the Ca2+channel TRPC3 and the PLCγ to the AT1R-β-arrestin complex, triggering G protein-independent ...

MiR-150 blunts cardiac dysfunction in mice with cardiomyocyte loss of β1-adrenergic receptor/β-arrestin signaling and controls a unique transcriptome

open access: yesCell Death Discovery, 2022
The β1-adrenergic receptor (β1AR) is found primarily in hearts (mainly in cardiomyocytes [CMs]) and β-arrestin-mediated β1AR signaling elicits cardioprotection through CM survival.

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.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

The α-arrestin ARRDC3 mediates ALIX ubiquitination and G protein-coupled receptor lysosomal sorting. [PDF]

open access: yes, 2015
The sorting of G protein-coupled receptors (GPCRs) to lysosomes is critical for proper signaling and cellular responses. We previously showed that the adaptor protein ALIX regulates lysosomal degradation of protease-activated receptor-1 (PAR1), a GPCR ...

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.
