Less tau reduces seizures and sudden death in severe epilepsy

Deleting or reducing expression of a gene that carries the code for tau, a protein associated with Alzheimer’s disease, can prevent seizures in a severe type of epilepsy linked to sudden death, said researchers at Baylor College of Medicine and the Mayo Clinic in Jacksonville, Fla., in a report in the current issue of the Journal of Neuroscience.

Study may offer clues to reverse cognitive deficits in humans

The ability to navigate using spatial cues was impaired in mice whose brains were minus a channel that delivers potassium — a finding that may have implications for humans with damage to the hippocampus, a brain structure critical to memory and learning, according to a Baylor University researcher.

Two genes affect anxiety, behavior in mice with too much MeCP2

The anxiety and behavioral issues associated with excess MeCP2 protein result from overexpression of two genes (Crh [corticotropin-releasing hormone] and Oprm 1 [mu-opioid receptor MOR 1]), which may point the way to treating these problems in patients with too much of the protein, said Baylor College of Medicine scientists in a report that appears online in the journal Nature Genetics.
