Deficiency in cystathionine beta synthase (CBS) leads to high plasma homocysteine concentrations and causes hyperhomocysteinemia, a common risk factor for vascular disease, stroke and possibly neurodegenerative diseases. Various neuronal diseases have been associated with hyperhomocysteinemia, but the molecular mechanisms of homocysteine toxicity are(More)
FE65 is an adaptor protein that interacts with the cytoplasmic tail of the amyloid precursor protein (APP). In cultured non-neuronal cells, the formation of the FE65-APP complex is a key element for the modulation of APP processing, signalling and beta-amyloid (Abeta) production. The functions of FE65 in vivo, including its role in the metabolism of(More)
Alzheimer's disease (AD) patients tend to have increased plasma levels of homocysteine. However, it is unclear whether abnormality in homocysteine levels is a primary cause of Alzheimer's disease or a disease marker. In order to investigate the relative impact of Alzheimer's disease on plasma homocysteine levels, total plasma homocysteine levels were(More)
