title: EAAT1 and EAAT2 immunoreactivity in transgenic mice with a G93A mutant SOD1 gene.
abstract: Immunocytochemical and quantitative analyses were used to correlate the localisation of excitatory amino acid transporter proteins EAAT1, EAAT2 with time in spinal motoneurones of presymptomatic and symptomatic mice with the G93A mutant SOD1 gene. Specimens from age-matched non-transgenic wild-type mice served as controls. EAAT1 and EAAT2 immunoreactivity was well-preserved in the gray matter in both controls and transgenic mice at all ages, and there was no difference in the expression of EAAT1 and EAAT2 immunoreactivity between controls and transgenic mice. These findings suggest that EAAT1 and EAAT2 may not play a pivotal role in the degeneration of motoneurons in this animal model.
