title: [Ionotropic glutamate receptor trafficking--there and back again].
abstract: Glutamate is a major excitatory neurotransmitter in brain. It engages mainly ionotropic glutamate receptors of AMPA and NMDA type. Thus, regulation of the number and properties of the receptors is crucial for correct neuronal communication, but also contributes to various forms of synaptic plasticity, namely neuronal development, learning and memory. Glutamate receptors are not static components of synapses. On the contrary, they are continuously delivered and removed from postsynaptic membranes and this process is regulated by synaptic activity, Receptor trafficking to synapses is a multi-step process, involving exit from endoplasmic reticulum, transport along dendrites, incorporation to postsynaptic membrane and finally removing them from synapses. The transport is regulated by numerous proteins, especially those bearing PDZ domains, or by receptors themselves.
