Group I metabotropic glutamate receptors are expressed in the chicken retina and by cultured retinal amacrine cells [PDF]
Glutamate is well established as an excitatory neurotransmitter in the vertebrate retina. Its role as a modulator of retinal function, however, is poorly understood.

Permissive role for mGlu1 metabotropic glutamate receptors in excitotoxic retinal degeneration [PDF]
Neuroprotection is an unmet need in eye disorders characterized by retinal ganglion cell (RGC) death, such as prematurity-induced retinal degeneration, glaucoma, and age-related macular degeneration.

A number of studies suggest that OLGs (oligodendrocytes), the myelinating cells of the central nervous system, are also a source of trophic molecules, such as neurotrophins that may influence survival of proximate neurons.

L-Glutamate supplementation improves small intestinal architecture and enhances the expressions of jejunal mucosa amino acid receptors and transporters in weaning piglets. [PDF]
L-Glutamate is a major oxidative fuel for the small intestine. However, few studies have demonstrated the effect of L-glutamate on the intestinal architecture and signaling of amino acids in the small intestine.

Glutaminolysis drives membrane trafficking to promote invasiveness of breast cancer cells
Glutamine metabolism is well known to support tumour growth. Here the authors show that cancer cells also utilize glutamine to promote invasiveness by converting it to glutamate, which upon secretion activates metabotropic glutamate receptors to ...

Sequences within the C terminus of the metabotropic glutamate receptor 5 (mGluR5) are responsible for inner nuclear membrane localization [PDF]
Traditionally, G-protein-coupled receptors (GPCR) are thought to be located on the cell surface where they transmit extracellular signals to the cytoplasm.

A Review of Molecular Imaging of Glutamate Receptors
Molecular imaging with positron emission tomography (PET) and single photon emission computed tomography (SPECT) is a well-established and important in vivo technique to evaluate fundamental biological processes and unravel the role of neurotransmitter ...

Neuropharmacological targets for drug action in vestibular sensory pathways [PDF]
The use of pharmacological agents is often the preferred approach to the management of vestibular dysfunction. In the vestibular sensory pathways, the sensory neuroepithelia are thought to be influenced by a diverse number of neuroactive substances that ...

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...
