Abstract:
Postmitotic neurons were generated from the human NT2 teratocarcinoma cell line in a novel cell aggregate differentiation procedure. The NT2 model neurons express punctate immunoreactivity for synapsin and for cell markers related to GABAergic and glutamatergic neurotransmission. Using the outside-out patch-clamp configuration, we characterized the kinetics of currents elicited by a rapid application of the amino acid neurotransmitters. Moreover, we detected spontaneous postsynaptic currents in glia free cell cultures that may result from the firing activity of glutamatergic and GABAergic NT2 neurons. These cultured spontaneously active networks may be a useful tool to analyze factors that modulate the formation and efficacy of synapses between human neurons.

Synaptic Signaling
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...
