Molecular mechanisms: MeCP2 loss ups signal strength

by  /  3 August 2011

A study using action potentials, the electrical impulses that trigger signaling, shows that neurons lacking MeCP2, the Rett syndrome protein, have stronger neuronal signals compared with controls, according to a study published in the July Journal of Neurophysiology.

Genetics: Deep sequencing reveals rare mutations

by  /  5 April 2011

Rare mutations with strong effects play a key role in autism and schizophrenia, according to a study published in February in PLoS Genetics. The study identifies rare harmful mutations in three candidate genes that are more common in individuals with one of the disorders than in controls.

Molecular mechanisms: Neuroligin-4 induces synapses in a dish

by  /  23 March 2011

Neuroligin-4, a protein associated with autism, is located at synapses — the junctions between neurons — that inhibit signals in the brain, according to a study published in February in the Proceedings of the National Academy of Sciences. The protein can also single-handedly induce neurons derived from human stem cells to form synapses, according to another study in the same issue.
