title: [Subtypes of glutamate receptor and their distribution in the somatic membrane of neurons freshly isolated from rat DRG].
abstract: The aim of the present study was to investigate the distribution and coexistence of glutamate (Glu) receptor subtypes in the isolated rat DRG neurons as identified by the recorded NMDA-, KA- or QA/AMPA-activated current using whole-cell patch-clamp technique. Of the 37 identified neurons, 15 contain only a single subtype receptor, 13 with two kind subtype receptors, only 4 with all subtype receptors. With regard the frequency of occurrence of the three types of receptors, the NMDA, KA and QA/AMPA subtype were found present respectively in 26 (70.3%), 7 (18.9%) and 21 (56.8%) of the recorded cells.
