Single‐Cell Transcriptomics and Metabolomics Reveal Glutamate Dehydrogenase as a Central Regulator of Nitrogen Metabolic Remodeling During Alkalinity Adaptation in Crustaceans

Advanced Science, EarlyView.
Single‐cell transcriptomics reveals the cellular response of Macrobrachium hainanense to carbonate alkalinity stress. Alkalinity stress impairs branchial ammonia excretion, induces mitochondrial dysfunction, and drives cell‐type‐specific changes in gills and hemocytes.

Targeting β2‐Adrenergic Receptor Stability With Lycorine Reveals a Host‐Directed Pathway for Antiviral Defense Against Poxviruses

Advanced Science, EarlyView.
Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we

The effect of arrestin conformation on the recruitment of c-Raf1, MEK1, and ERK1/2 activation.

PLoS ONE, 2011
Arrestins are multifunctional signaling adaptors originally discovered as proteins that "arrest" G protein activation by G protein-coupled receptors (GPCRs).

Von In‐Silico bis In‐Cerebro – Entwicklung des Orexinrezeptor Antagonisten „Photorexant“ zur Photomodulation In Vitro und im Gehirn der Maus

Angewandte Chemie, EarlyView.
Durch einen strukturbasierten Designansatz wurden photoschaltbare Derivate des von der FDA zugelassenen Arzneistoffes Suvorexant entwickelt, gedockt, synthetisiert und pharmakologisch an den Orexin‐1‐ und 2‐Rezeptoren (OX1R und OX2R) charakterisiert.

A lipidated peptide derived from the C-terminal tail of the vasopressin 2 receptor shows promise as a new β-arrestin inhibitor

Pharmacological Research
β-arrestins play pivotal roles in seven transmembrane receptor (7TMR) signalling and trafficking. To study their functional role in regulating specific receptor systems, current research relies mainly on genetic tools, as few pharmacological options are ...

Arrestin Development: Emerging Roles for β-arrestins in Developmental Signaling Pathways [PDF]

Developmental Cell, 2009
Arrestins were identified as mediators of G protein-coupled receptor (GPCR) desensitization and endocytosis. However, it is now clear that they scaffold many intracellular signaling networks to modulate the strength and duration of signaling by diverse types of receptors--including those relevant to the Hedgehog, Wnt, Notch, and TGFbeta pathways--and ...

In Silico to In Cerebro—Development of the Orexin Receptor Antagonist “Photorexant” for Photomodulation In Vitro and in Mouse Brains

Angewandte Chemie International Edition, EarlyView.
Following a structure‐based design approach, photoswitchable derivatives of the FDA‐approved drug suvorexant were designed, docked, synthesized, and characterized pharmacologically at the orexin 1 and 2 receptors (OX1R and OX2R). Optimized “photorexant” showed up to an 11‐fold difference in IC50 between photoisomers, enabled dynamic and reversible ...

Mortality risk stratification for Takotsubo syndrome: Evaluating CRP measurement alongside the InterTAK prognostic score

ESC 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.

The multifaceted functions of β-arrestins and their therapeutic potential in neurodegenerative diseases

Experimental and Molecular Medicine
Arrestins are multifunctional proteins that regulate G-protein-coupled receptor (GPCR) desensitization, signaling, and internalization. The arrestin family consists of four subtypes: visual arrestin1, β-arrestin1, β-arrestin2, and visual arrestin-4 ...

Nedd4 E3 ligase and beta-arrestins regulate ubiquitination, trafficking, and stability of the mGlu7 receptor

eLife, 2019
The metabotropic glutamate receptor 7 (mGlu7) is a class C G protein-coupled receptor that modulates excitatory neurotransmitter release at the presynaptic active zone. Although post-translational modification of cellular proteins with ubiquitin is a key
