Abstract:We investigated age-related changes in excitatory amino acid transport sites and FK506 binding protein (FKBP) in 3-week-, and 6-, 12-, 18- and 24-month-old Fischer 344 rat brains using receptor autoradiography. Sodium-dependent D-[3H]aspartate and [3H]FK506 were used to label excitatory amino acid transport sites and immunophilin (FKBP), respectively. In immature rats (3-week-old), sodium-dependent D-[3H]aspartate binding was lower in the frontal cortex, parietal cortex, striatum, nucleus accumbens, whole hipp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
