Endocrinology and the brain: Corticotropin-Releasing Hormone signaling [PDF]

, 2017
Corticotropin-releasing hormone (CRH) is a key player of basal and stress activated responses in the hypothalamic-pituitary-adrenal axis (HPA) and in extrahypothalamic circuits, where it functions as a neuromodulator to orchestrate humoral and behavioral

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

Advanced 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

Identification of chemokine receptors as potential modulators of endocrine resistance in oestrogen receptor–positive breast cancers [PDF]

, 2014
Introduction Endocrine therapies target oestrogenic stimulation of breast cancer (BC) growth, but resistance remains problematic. Our aims in this study were (1) to identify genes most strongly associated with resistance to endocrine therapy by ...

Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

Advanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

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

Nature 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 ...

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

, 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

Nano‐Gs‐Protein Peptidomimetika: Rationales Design von Peptiden, die vom C‐Terminus von Gα abgeleitet sind und Schlüsselkomponenten der Gs‐β2AR‐Wechselwirkungen nachahmen

Angewandte Chemie, EarlyView.
G Protein‐gekoppelte Rezeptoren (GPCRs) sind wichtige therapeutische Zielstrukturen. Die Modulation der GPCR‐Aktivität über intrazelluläre Bindungsstellen gewinnt zunehmend an Bedeutung. Ein strukturell und computergestützter Ansatz ermöglichte die Entwicklung kleiner, vom G Protein abgeleiteter Peptidomimetika, die gezielt an die intrazelluläre ...

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

Cell 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.

The Effects of Apelin and Elabela Ligands on Apelin Receptor Distinct Signaling Profiles

Frontiers in Pharmacology, 2021
Apelin and Elabela are endogenous peptide ligands for Apelin receptor (APJ), a widely expressed G protein-coupled receptor. They constitute a spatiotemporal dual ligand system to control APJ signal transduction and function.
