8. Fig. 7
Roles of B vitamins and homocysteine in one-carbon metabolism, transsulfuration pathway and brain function. Homocysteine can be transported into neurons via a specific membrane transporter. Remethylation of homocysteine to methionine occurs in the presence of folate and B12. Methionine is an important source of methyl groups in the brain. Homocysteine can also be converted to cysteine (a precursor of glutathione) in the presence of B6. Homocysteine can cause DNA damage directly or through reduction in DNA methylation, leading to synaptic dysfunction and apoptosis. Homocysteine can lead to excitotoxicity through direct actions on glutamate receptors. Although the pathway for remethylation of homocysteine via BHMT does not occur in the brain, it may still influence brain function through actions on systemic homocysteine levels. Adapted from Mattson and Shea [237]. B2 = Vitamin B2 (riboflavin); BHMT = betaine-homocysteine methyltransferase; MS = methionine synthase; MTHFR = 5, 10-methylenetetrahydrofolate reductase; SAH = S-adenosylhomocysteine; SAM = S-adenosylmethionine.
