MeCP2 loss leads to smaller neurons in brain region

by  /  18 November 2009

Deleting MeCP2, the gene that’s mutated in Rett syndrome, alters both the size and function of neurons in the mouse brain — at least in one brain region, the locus ceruleus — according to a 30 September report in the Journal of Neuroscience.

Treating Rett syndrome

by  /  17 November 2008

Treatment with the insulin-like growth factor (IGF) greatly improves the health of mouse models of Rett syndrome ― a regressive genetic disorder that causes mental retardation, seizures, and autistic features ― according to unpublished researched presented this morning at the Society for Neuroscience conference.
