AMPA receptors: potential implications in development and disease.
Alpha-amino-3-hydroxy-5-methyl-4-isoxazoleproprionic acid (AMPA) receptors are one type of ionotropic glutamate receptor involved in rapid excitatory synaptic transmission. AMPA receptors have been increasingly implicated in long-term potentiation, and recent evidence suggests that they may play a role in disorders affecting the nervous system. The finding that early in postnatal development AMPA receptors are not expressed has lately been the focus of much attention. Resolving the factors involved in AMPA receptor expression suggests that their induction is a developmentally regulated process with the possibility that alterations in receptor expression may be correlated with pathology in neurological disorders. This paper provides an overview of factors involved in AMPA receptor induction as well as of their role in plasticity and neuronal pathologies.
