Aging and the blood-brain barrier: changes in the carrier-mediated transport of peptides in rats.

abstract：:Multiple sclerosis (MS) is a chronic inflammatory CNS disorder, resulting in progressive neurological dysfunction. The disease has a higher incidence in Caucasian Americans (CA) than African Americans (AA); however, the latter may have a more aggressive disease course. We used cluster analysis to determine whether the...
