Folate (vitamin B9) and vitamin B12 act as cofactors in the one-carbon metabolism that regulates transmethylation reactions involved in epigenetic mechanisms. A deficiency in folate and/or B12 decreases the generation of methionine from homocysteine, a toxic amino acid that has been associated with pathologies of the central nervous system at all ages (spina bifida, Alzheimer's disease...). In order to depict the cellular and molecular mechanisms implicated in the response to the deficiency in these micronutrients, two new cell models have been developed. Thus, we have analyzed the effects of folate deficiency on proliferation, differentiation and neuroplasticity of neuronal progenitors obtained from the hippocampus of rat embryos, i.e. the...
