Moderate hyperhomocysteinemia is associated with several diseases, including coronary artery disease, stroke, Alzheimer's disease, schizophrenia, and spina bifida. However, the mechanisms for their pathogenesis are unknown but could involve the interaction of homocysteine or its metabolites with
BACKGROUND
L-Homocysteine (Hcy) is a non-proteinogenic α-amino acid synthesized from dietary methionine. In healthy humans, high Hcy levels are a risk factor for cardiovascular diseases,
stroke and type 2 diabetes. A recent study reports that Hcy reacts with Cys

Hyperhomocysteinemia has been implicated in several neurodegenerative disorders including ischemic stroke. However, the pathological consequences of ischemic insult in individuals predisposed to hyperhomocysteinemia and the associated etiology are unknown. In this study, we evaluated the outcome of
Hyperhomocysteinemia is an independent risk factor for stroke and neurological abnormalities. However, the underlying cellular mechanisms by which elevated homocysteine can promote neuronal death is not clear. In the present study we have examined the role of NMDA receptor-mediated activation of the
Hyperhomocysteinemia is associated with various pathologies including cardiovascular disease, stroke, and cognitive dysfunctions. Systemic administration of homocysteine can trigger seizures in animals, and patients with homocystinuria suffer from epileptic seizures. Available data suggest that
