Methionine recycling in brain: a role for folates and vitamin B-12.

abstract：:Mutations in the presenilin 1 (PS1) gene are associated with autosomal dominant, early-onset, familial Alzheimer's disease and result in increased release of the hyperaggregatable 42-amino acid form of the amyloid beta-peptide (A(beta)42). To determine which subcellular compartments are potential source(s) of released...
