Spatiotemporal dynamics of β‐arrestin‐mediated Src activation in 5‐HT7 receptor signaling pathway

open access: yesThe FEBS Journal, EarlyView.
GPCRs induce distinct cellular responses via G protein‐ or β‐arrestin‐mediated signaling pathways. This study revealed that β‐arrestin‐biased 5‐HT7R ligand induces slow, sustained Src activation, contrasting with transient G protein‐mediated activation.

T‐2 Toxin‐Mediated β‐Arrestin‐1 O‐GlcNAcylation Exacerbates Glomerular Podocyte Injury via Regulating Histone Acetylation

open access: yesAdvanced Science
T‐2 toxin causes renal dysfunction with proteinuria and glomerular podocyte damage. This work explores the role of metabolic disorder/reprogramming‐mediated epigenetic modification in the progression of T‐2 toxin‐stimulated podocyte injury.

Discovery of functionally selective C5aR2 ligands: novel modulators of C5a signalling. [PDF]

open access: yes, 2016
The complement cascade is comprised of a highly sophisticated network of innate immune proteins that are activated in response to invading pathogens or tissue injury. The complement activation peptide, C5a, binds two seven transmembrane receptors, namely

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

open access: yesAndrology, Volume 14, Issue 4, Page 978-991, May 2026.
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.

Look Who Is Talking: Extracellular Vesicles as Mediators of Intercellular and Interorgan Communication

open access: yesComprehensive Physiology, Volume 16, Issue 2, April 2026.
Extracellular vesicles (EVs) mediate intercellular and interorgan communication during both physiological and pathological conditions. EVs include exosomes, ectosomes, and apoptotic bodies and contain bioactive molecules. EVs are delivered to proximal cells or can travel in bodily fluids and reach distant organs, where they trigger a response from the ...

Cancer Neuroscience: Innovative Conception and Emerging Strategy of Therapy

open access: yesMedComm, Volume 7, Issue 4, April 2026.
In this review, we summarize nerve–cancer interactions and conclude two additional interactions, “perineural invasion” and “neuro‐microbic‐oncology.” Emphasizing the important role of nerves in tumor progression. The nervous system also contributes to the development of cancer comorbidities such as cancer depression and cognitive dysfunction.

Signal Amplification in the HPT Axis—Evidence for Its Existence, Location, Significance, and Molecular Mechanisms

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Thyroid hormones (THs) are under negative feedback regulation via the hypothalamic–pituitary‐thyroid (HPT) axis. How this axis operates to keep the circulating THs within a narrow physiological range is not well understood quantitatively. Led by the design principle of robust homeostatic feedback control, here we review and synthesize the ...

Melatonin and the Dental Pulp: A Scoping Review

open access: yesInternational Endodontic Journal, Volume 59, Issue 4, Page 590-613, April 2026.
ABSTRACT Background In general medicine, melatonin is known to enhance wound healing and promote stem cell differentiation. Its potential relevance in endodontics, however, remains underexplored. Objectives This scoping review aimed to systematically assess the available evidence on the effects of melatonin (a) on dental pulp tissue and (b) on human ...

Pepducin-mediated cardioprotection via β-arrestin-biased β2-adrenergic receptor-specific signaling [PDF]

open access: yes, 2018
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 ...

Mechanistic insights into the versatile stoichiometry and biased signaling of the apelin receptor-arrestin complex

open access: yesNature Communications
The apelin receptor (APJR) plays a pivotal role in regulating cardiovascular and metabolic health1,2. Understanding the mechanisms of biased agonism at APJR is crucial for drug discovery, as stimulation of the β-arrestin pathway may lead to some adverse ...
