Increased accuracy of ligand sensing by receptor diffusion on cell surface [PDF]
Physical Review E 82, 041902 (2010), 2010 The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration.

Oncogenic activities of metabotropic glutamate receptor 1 (Grm1) in melanocyte transformation [PDF]
Pigment Cell & Melanoma Research, 2008 SummaryPreviously, we reported a transgenic mouse line, TG‐3, that develops spontaneous melanoma with 100% penetrance. We demonstrated that ectopic expression of Grm1 in melanocytes was sufficient to induce melanoma in vivo. In this present study, the transforming properties of Grm1 in two cultured immortalized melanocytes were investigated.

Acute Alcohol-Induced Changes Measured With Metabotropic Glutamate Receptor 5 Positron Emission Tomography. [PDF]
Addict BiolThis proof‐of‐concept study provides evidence that acute alcohol administration reduces mGluR5 availability and increases relative blood flow in the human brain, as measured by [11C]ABP688 PET. The observed effects align with preclinical evidence of alcohol‐induced glutamate release.

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

Towards the convergent therapeutic potential of GPCRs in autism spectrum disorders [PDF]
arXiv, 2022 Changes in genetic and/or environmental factors to developing neural circuits and subsequent synaptic functions are known to be a causative underlying the varied socio-emotional behavioural patterns associated with autism spectrum disorders (ASD). Seven transmembrane G protein-coupled receptors (GPCRs) comprising the largest family of cell-surface ...

Direct imaging of lateral movements of AMPA receptors inside synapses [PDF]
EMBO J 22, 18 (15/09/2003) 4656-65, 2007 Trafficking of AMPA receptors in and out of synapses is crucial for synaptic plasticity. Previous studies have focused on the role of endo/exocytosis processes or that of lateral diffusion of extra-synaptic receptors. We have now directly imaged AMPAR movements inside and outside synapses of live neurons using single-molecule fluorescence microscopy ...

Group 1 Metabotropic Glutamate Receptors in Neurological and Psychiatric Diseases: Mechanisms and Prospective [PDF]
The Neuroscientist, 2021 Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors that are activated by glutamate in the central nervous system (CNS). Basically, mGluRs contribute to fine-tuning of synaptic efficacy and control the accuracy and sharpness of neurotransmission.

High- and low-conductance NMDA receptors are present in layer 4 spiny stellate and layer 2/3 pyramidal neurons of mouse barrel cortex [PDF]
Physiological Reports, 30th Dec. 2016, Vol. 4 no. e13051, 2016 NMDA receptors are ion channels activated by the neurotransmitter glutamate in the mammalian brain and are important in synaptic function and plasticity, but are also found in extrasynaptic locations and influence neuronal excitability. There are different NMDA receptor subtypes which differ in their single-channel conductance.
