Immunohistochemical localization of N-acetylaspartate in rat brain.
N-acetylaspartate (NAA) is one of the most prevalent compounds in the mammalian nervous system. As such, NAA largely contributes to the major peak on water-suppressed proton magnetic resonance spectra. Highly specific antibodies to NAA demonstrate that this compound is discretely localized in a substantial number of neurons throughout the extent of the rat CNS. N-acetylaspartylglutamate (NAAG) ...
متن کاملLongitudinal whole-brain N-acetylaspartate concentration in healthy adults.
BACKGROUND AND PURPOSE Although NAA is often used as a marker of neural integrity and health in different neurologic disorders, the temporal behavior of WBNAA is not well characterized. Our goal therefore was to establish its normal variations in a cohort of healthy adults over typical clinical trial periods. MATERIALS AND METHODS Baseline amount of brain NAA, Q(NAA), was obtained with nonloc...
متن کاملN-acetylaspartate in brain – studies on efflux and function
N-acetylaspartate (NAA) is an amino acid derivative present in high concentration in the brain. The function of NAA is still unsettled in spite of 50 years of research. The mainly neuronal synthesis and glial breakdown of NAA requires a well regulated neuronal efflux and glial uptake. In the present work hippocampal slices were used to study how NAA efflux from neurons is regulated and to furth...
متن کاملSerial whole-brain N-acetylaspartate concentration in healthy young adults.
Although the concentration of N-acetylaspartate (NAA) is often used as a neuronal integrity marker, its normal temporal variations are not well documented. To assess them over the 1-2 year periods of typical clinical trials, the whole-brain NAA concentration was measured longitudinally, over 4 years, in a cohort of healthy young adults. No significant change (adjusted for both sex and age) was ...
متن کاملOriginal Articles Extracellular N-Acetylaspartate in Human Traumatic Brain Injury
N-acetylaspartate (NAA) is an amino acid derivative primarily located in the neurons of the adult brain. The function of NAA is incompletely understood. Decrease in brain tissue NAA is presently considered symptomatic and a potential biomarker of acute and chronic neuropathological conditions. The aim of this study was to use microdialysis to investigate the behavior of extracellular NAA (eNAA)...
