Regulation of Melatonin and Neurotransmission in Alzheimer’s Disease [PDF]
International Journal of Molecular Sciences, 2021 Alzheimer’s disease is a neurodegenerative disorder associated with age, and is characterized by pathological markers such as amyloid-beta plaques and neurofibrillary tangles. Symptoms of AD include cognitive impairments, anxiety and depression.

Epilepsia, 1995
Summary: Some evidence indicates that in some types of focal epilepsy the enhanced excitability is due in part to impaired γ‐aminobutyric acid (GABA)ergic inhibitory feedback. One form that this can take is impaired excitatory input to GABAergic interneurons.

Annual Review of Nutrition, 2011
A subset of glutamatergic synapses in the central nervous system contains zinc; it is sequestered into the lumen of synaptic vesicles, where it colocalizes with glutamate. Extracellularly applied zinc is known to interact with various postsynaptic receptors and channels; however, the role of endogenous vesicular zinc is still an enigma.

Neurotransmission: sites at which drugs modify neurotransmission
1983The idea that nerves may communicate with other cells by releasing small quantities of chemicals at their junctions may have arisen from observations of the effects of poisons on animals. It was found that some poisons could mimic the effects of stimulating certain nerves, and it must have occurred to somebody that nerves release chemicals in response ...

Survey of Ophthalmology, 1985
The mammalian retina is classically divided into ten layers which contain the neuronal elements identified as photoreceptors, horizontal cells, bipolar cells, amacrine cells and ganglion cells. Using various neuroscientific techniques possible neurotransmitter substances have been assigned to each of these cell types.

Astrocytes in glutamate neurotransmission
The FASEB Journal, 1995Astrocytes maintain ionic, amino acid neurotransmitter, and water homeostasis in the extracellular space of the brain. The anatomy of the cells, with their network formation and their capacity to react to and produce humoral and long‐distance, slow‐speed transfer of information within the syncytium, makes them appear to be a class ...

Roles of glutamine in neurotransmission
Neuron Glia Biology, 2010Glutamine (Gln) is found abundantly in the central nervous system (CNS) where it participates in a variety of metabolic pathways. Its major role in the brain is that of a precursor of the neurotransmitter amino acids: the excitatory amino acids, glutamate (Glu) and aspartate (Asp), and the inhibitory amino acid, γ-amino butyric acid (GABA).

Neurotransmission in the Human Labyrinth
2002Different neuroactive substances have been found in the efferent pathways of both the olivocochlear and vestibular systems. In the present study, the distribution and role of three neurotransmitters, choline acetyltransferase (ChAT), gamma aminobutyric acid (GABA), and enkephalin were investigated in the human labyrinth of 4 normal-hearing individuals.
