Critical Role for Gi/o-Protein Activity in the Dorsal Striatum in the Reduction of Voluntary Alcohol Intake in C57Bl/6 Mice

Frontiers in Psychiatry, 2018
The transition from non-dependent alcohol use to alcohol dependence involves increased activity of the dorsal striatum. Interestingly, the dorsal striatum expresses a large number of inhibitory G-protein-coupled receptors (GPCRs), which when activated ...

Unraveling the molecular architecture of a G protein-coupled receptor/β-arrestin/Erk module complex [PDF]

, 2015
International audienceβ-arrestins serve as signaling scaffolds downstream of G protein-coupled receptors, and thus play a crucial role in a plethora of cellular processes.

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

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).

Does GDNF exert its neuroprotective effects on photoreceptors in the rd1 retina through the glial glutamate transporter GLAST? [PDF]

, 2005
PURPOSE: We previously demonstrated that exogenous glial cell line-derived neurotrophic factor (GDNF) induces histological and functional protection of photoreceptors in the retinal degeneration (rd1) mouse model.

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

British Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Concepts of GPCR-controlled navigation in the immune system

, 2019
G-protein-coupled receptor (GPCR) signaling is essential for the spatiotemporal control of leukocyte dynamics during immune responses. For efficient navigation through mammalian tissues, most leukocyte types express more than one GPCR on their surface ...

Cannabigerol reverses mechanical allodynia through α2A‐adrenergic modulation of thalamocortical signaling in chemotherapy‐induced neuropathy

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Chemotherapy‐induced peripheral neuropathy (CIPN) is a prevalent and treatment‐resistant side effect of platinum‐based chemotherapy, characterised by mechanical allodynia. Cannabigerol (CBG), a non‐psychoactive cannabinoid, has shown antinociceptive potential, but its site and mechanism of action remain unclear.

Deconvolution of complex G protein-coupled receptor signaling in live cells using dynamic mass redistribution measurements [PDF]

, 2010
Label-free biosensor technology based on dynamic mass redistribution (DMR) of cellular constituents promises to translate GPCR signaling into complex optical 'fingerprints' in real time in living cells.

Divergence in μ and δ opioid receptor pharmacology in neurons and antinociceptive efficacy in neuropathic pain: Insights from MP135 and CYM51010

British Journal of Pharmacology, EarlyView.
Background and purpose Opioids targeting the μ opioid receptor remain largely ineffective in neuropathic pain conditions, emphasizing the need for novel therapeutic strategies. MP135 was reported to reduce thermal nociception in naive animals by activating μ‐δ opioid receptor heteromers.
