A Novel Class of “Super‐Strained” Spiro Heterocycles: Gateway to 1‐Azaspiro[3.3]heptane Derivatives, and Biological Validation

Angewandte Chemie, EarlyView.
A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

Novel insights in β-adrenergic receptor signaling

, 2018
The adrenergic receptors (ARs) are G-protein-coupled receptors that in response to stimuli activate several intracellular signaling regulating key biologic functions and affecting several pathological conditions, mainly cardiovascular diseases (CV ...

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

Advanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Agonistic autoantibodies to the alpha(1)-adrenergic receptor and the beta(2)-adrenergic receptor in Alzheimer's and vascular dementia

, 2012
Although primary causes of Alzheimer's and vascular dementia are unknown, the importance of preceding vascular lesions is widely accepted. Furthermore, there is strong evidence for the involvement of autoimmune mechanisms.

Effect of β3-adrenergic receptor agonists on [18F] fluorodeoxyglucose uptake in brown adipose tissues in positron emission tomography images of elderly patients

EJNMMI Research
Background Brown adipose tissues (BAT) are highly vascularized, mitochondria-rich tissues involved in thermogenesis. Physiological [18F]fluorodeoxyglucose ([18F]FDG) uptake in BAT can be influenced by several factors, including the use of medications ...

Suppressive Effects of Bee Venom Acupuncture on Paclitaxel-Induced Neuropathic Pain in Rats: Mediation by Spinal α2-Adrenergic Receptor

Toxins, 2017
Paclitaxel, a chemotherapy drug for solid tumors, induces peripheral painful neuropathy. Bee venom acupuncture (BVA) has been reported to have potent analgesic effects, which are known to be mediated by activation of spinal α-adrenergic receptor.

CK2α Deficiency Drives Myocardial Fibrosis via Desmin‐Induced Mitochondrial Dysfunction

Advanced Science, EarlyView.
CK2α preserves mitochondrial homeostasis by phosphorylating Desmin to recruit Cryab, ensuring proper filament assembly. CK2α deficiency disrupts this interaction, causing mitochondrial dysfunction, metabolic shifts, bioenergetic failure, and oxidative stress—ultimately establishing a pro‐fibrotic environment that drives cardiac fibrosis.

Adrenergic β2 receptor activation stimulates anti-inflammatory properties of dendritic cells in vitro.

PLoS ONE, 2014
Vagal nerve efferent activation has been shown to ameliorate the course of many inflammatory disease states. This neuro-modulatory effect has been suggested to rest on acetylcholine receptor (AChR) activation on tissue macrophages or dendritic cells (DCs)
