Glutamate, the principal retinal neurotransmitter, can also act as a toxin when present in excessive concentrations as may occur in pathologies such as retinal ischemia or more generally in cerebral neuronal degenerative disease.

β¦ Synopsis
According to the classical model of insect neurogenesis, neuron fate and survival is determined largely by cell autonomous mechanisms with no requirement for cell-cell interactions to control the total number of neurons. In a recent paper by Booth et al.,(1) however, the central tenet of this model has been called into question. Using a combination of mutations and targeted glial ablation, this paper shows that, contrary to common thinking, neuron survival in the embryonic nervous system of Drosophila is dependent upon normal glial function. This surprising result suggests that insect neurogenesis may have more in common with vertebrate neurogenesis than previously thought.

## Abstract The ensheathment of neurons and their axons creates an ionβsensitive microenvironment that allows rapid conduction of nerve impulses. One of the fundamental questions about axonal ensheathment is how insulating glial cells wrap around axons. The mechanisms that underlie insulation of ax
Two membrane-localized transporter proteins (GLYT1 and GLYT2) are responsible for removal of extracellular glycine in the mammalian CNS. Whereas GLYT1 seems to be expressed mainly in glial cells, GLYT2 is neuronal. The highest concentrations of both transporters are found in glycinergic areas of the
Glutamate is the most abundant excitatory amino acid in the central nervous system. It has also been described as a potent toxin when present in high concentrations because excessive stimulation of its receptors leads to neuronal death. Glial influence on neuronal survival has already been shown in
The amino acid glutamate plays a key role in brain function. One of the major roles of glutamate is to mediate fast excitatory neurotransmission via activation of ionotropic glutamate receptors (iGluRs). More recently, however, it has become clear that glutamate also serves a regulatory function thr
The chordotonal (scolopidial) organ is a segmental stretch receptor (proprioceptor) and a four-celled organ of the peripheral nervous system of Drosophila. This organ has become a model in studies of embryogenesis involving molecular genetics and developmental biology. We determined how three glial
