Distribution of glycine receptors at central synapses: an immunoelectron microscopy study

The distribution of receptors for a neurotransmitter was investigated cytochemically for the first time in the central nervous system, at synapses established on cells of the ventral horn of the rat cervical spinal cord. Three monoclonal antibodies (mAb's) raised against glycine receptors were used. Immunofluorescent staining already showed discontinuous labeling at the surface of neurons, and ...

Distribution of glycine receptors on the membrane of a central neuron: an immunoelectron microscopy study.

The distribution of glycine receptors on the plasmalemma of the teleost Mauthner cell was examined with light and electron microscopy using monoclonal antibodies raised against the glycine receptors of the rat. These immunoglobulins recognize a peptide of 93 kDa associated with the intracellular side of the receptor complex. With indirect immunofluorescence, labeling appeared as small clusters ...

gamma-Aminobutyric acid-containing terminals can be apposed to glycine receptors at central synapses

The distributions of terminals containing gamma-aminobutyric acid (GABA) and of endings apposed to glycine receptors were investigated cytochemically in the ventral horn of the rat spinal cord. For this purpose, a polyclonal antibody raised to recognize glutamic acid decarboxylase (GAD), a synthetic enzyme for GABA, and three monoclonal antibodies (mAb's) directed against the glycine receptor w...

Glycine uptake governs glycine site occupancy at NMDA receptors of excitatory synapses.

Glycine uptake governs glycine site occupancy at NMDA receptors of excitatory synapses. J. Neurophysiol. 80: 3336-3340, 1998. At central synapses occupation of glycine binding sites of N-methyl--aspartate receptors (NMDA-Rs) is a necessary prerequisite for the excitatory neurotransmitter glutamate to activate these receptors. There is conflicting evidence as to whether glycine binding sites nor...
