Os receptores de glutamato incluem os receptores ionotrópicos (receptores AMPA, Kainato e N-metil-D-aspartato), que controlam diretamente os canais iônicos, e os receptores metabotrópicos que atuam através do sistema de segundos mensageiros. Os receptores de glutamato são os mediadores mais comuns da transmissão sináptica excitatória rápida do sistema nervoso central. Eles também têm sido envolvidos nos mecanismos de memória e de várias doenças.<p>Fonte: DeCS.
