Researchers were able to improve walking and prolong survival in a mouse model by tweaking potassium levels

By boosting the ability of a specific type of cell to absorb potassium in the brain, UCLA researchers were able to improve walking and prolong survival in a mouse model of Huntington’s disease.

Their findings, published March 30 in the online edition of the journal Nature Neuroscience, could point to new drug targets for treating the devastating disease, which strikes one in every 20,000 Americans. (more…)

Misregulated genes may have big autism role

A genetic pathway involving proteins in the endosomes of cells appears to be misregulated in the brains of children with autism, according to a newly published statistical analysis in the journal Molecular Psychiatry. Previously the genes were shown to cause rare forms of the disease but the new study suggests they have a wider role.

PROVIDENCE, R.I. [Brown University] — A new study finds that two genes individually associated with rare autism-related disorders are also jointly linked to more general forms of autism. The finding suggests a new genetic pathway to investigate in general autism research. (more…)

GAINESVILLE, Fla. — By analyzing the genes of bacteria, University of Florida researchers have moved a step closer to pinpointing how two brain disorders common in small-breed dogs occur.

The researchers found that the bacteria, known as Mycoplasma canis, invade dog’s cells and suppress their immune system responses. (more…)

More Sophisticated Wiring, Not Just a Bigger Brain, Helped Humans Evolve Beyond Chimps

Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin?

A new UCLA study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our closest relative. The identification of these genes could improve understanding of human brain diseases like autism and schizophrenia, as well as learning disorders and addictions.

The research appears Aug. 22 in the advance online edition of the journal Neuron. (more…)

UD researchers develop novel technique for early detection of misfolded protein

University of Delaware assistant professor David W. Colby is co-author of a paper in the March 23 issue of the Journal of Biological Chemistry that suggests protein misfolding may occur early in the pathogenesis, or development, of Huntington’s disease.

Huntington’s disease (HD) is one of several neurological diseases, such as Alzheimer’s disease or prion disease, associated with proteins that fold into abnormal structures. HD is characterized by progressive motor impairment, cognitive decline and behavioral abnormalities, and ultimately death. (more…)
