TL;DR

The data suggest that the age-related decline in glutamate binding to the NMDA receptor may predict a strain-specific reduction in NMDA-mediated processes (e.g. long-term potentiation, postsynaptic calcium fluxes).

Abstract

Glutamate binding to the N-methyl-D-aspartic acid (NMDA) receptor decreases in two strains of aged mice. In BALB/c mice the Bmax values decline 16% by 10 months and 45% by 30 months of age when compared to 3 months. The Kd increased more by 10 months (+29%) than by 30 months (+14%). In the C57Bl strain the Bmax was unaltered by 10 months but decreased 17% by 30 months. The Kd values, however, increased 121% by 10 months and 283% by 30 months of age. These data suggest that the age-related decline in glutamate binding to the NMDA receptor may predict a strain-specific reduction in NMDA-mediated processes (e.g. long-term potentiation, postsynaptic calcium fluxes).
