Metabolism peritumorous zone and alteration AMPAand NMDA-glutamate receptors in the pathogenesis of gliomas of the cerebral hemispheres
Abstract
Examined 12 patients with gliomas of the big hemispheres of a brain. Used immunoenzyme method for semiquantitative determination of the level of autoantibodies to NR2A-subunit of NMDA- and GluR1-subunit of AMPA-receptors of glutamate. All patients were performed positron emission tomography of the brain with 2 radiopharmaceuticals: 2-[18F] fluoro-2-deoxy-D-glucose and L-[methyl-11C]-methionine. Features of alteration of NMDA- and AMPA-receptors of a glutamate and sequence of changes of a metabolism in a perifocal zone in gliomas of the cerebral hemispheres are studied. It is shown pre-emptive increase the level of autoantibodies to GluR1- subunit of AMPA-receptors of glutamate in patients with gliomas, current with epileptic syndrome.
