Developing HaloTag and SNAP‐Tag Chemical Inducers of Dimerization to Probe Receptor Oligomerization and Downstream Signaling

Angewandte Chemie International Edition, Accepted Article.
Controlling protein‐protein interactions is critical for dissecting signaling pathways, especially those initiated by ligand‐receptor interactions which alter receptor oligomerization and drive downstream signaling cascades. Traditional methods for driving protein‐protein complexes are using antibodies that face limitations in terms of stoichiometry ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Metabotropic glutamate receptor 5 knockout rescues obesity phenotype in a mouse model of Huntington’s disease

Scientific Reports, 2022
Obesity represents a global health problem and is characterized by metabolic dysfunctions and a low-grade chronic inflammatory state, which can increase the risk of comorbidities, such as atherosclerosis, diabetes and insulin resistance.

Ionotropic glutamate receptors and their implications in cancer and cancer therapeutics

Biomedical and Biotechnology Research Journal, 2021
Glutamine, an excitatory neurotransmitter, is necessary for physiological as well as pathological processes. Other than neuronal disorders and/or cancers, glutamate receptors have also been associated with an array of other malignancies. The metabotropic

Diverse Subpopulations of Reactive Astrocytes Following Chronic Toxoplasma Infection

Glia, EarlyView.
Toxoplasma infection results in distinct astrocyte subpopulations. Chronically labeled reactive astrocytes appear transcriptionally plastic and can regain acute inflammatory responding and naive homeostatic astrocytic gene patterns in the presence of ongoing neuroinflammation.

Molecular‐Informed Network Analysis Unveils Fatigue‐Related Functional Connectivity in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Fatigue in Parkinson's disease (PD) is a prevalent and debilitating non‐motor symptom. Despite its significant impact on quality of life, the underlying neurochemical and network‐based mechanisms remain poorly understood. Objectives This observational study applied a multimodal imaging approach to explore potential links between the

Conformational diversity in class C GPCR positive allosteric modulation

Nature Communications
The metabotropic glutamate receptors (mGlus) are class C G protein-coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate.

Activated Nuclear Metabotropic Glutamate Receptor mGlu5 Couples to Nuclear Gq/11 Proteins to Generate Inositol 1,4,5-Trisphosphate-mediated Nuclear Ca2+ Release*

Journal of Biological Chemistry, 2008
Recently we have shown that the metabotropic glutamate 5 (mGlu5) receptor can be expressed on nuclear membranes of heterologous cells or endogenously on striatal neurons where it can mediate nuclear Ca2+ changes.

Lower Limbic Metabotropic Glutamate Receptor 5 Availability in Alcohol Dependence [PDF]

Journal of Nuclear Medicine, 2018
Animal studies suggest an important role for the metabotropic glutamate receptor subtype 5 (mGlu5) in the pathophysiology of alcohol dependence, but direct human evidence is lacking. The goal of this study was to investigate cerebral mGlu5 availability in alcohol-dependent subjects versus controls using 18F-3-fluoro-5-[(pyridin-3-yl)ethynyl ...

Recent Developments in the Optical Control of Adrenergic Signaling

Medicinal Research Reviews, EarlyView.
ABSTRACT Adrenoceptors (ARs) play a vital role in various physiological processes and are key therapeutic targets. The advent of optical control techniques, including optogenetics and photopharmacology, offers the potential to modulate AR signaling with precise temporal and spatial resolution. In this review, we summarize the latest advancements in the
