Study identifies how astrocytes regulate a neurotransmitter involved in sleep

Neuroscience researchers from Tufts University have found that our star-shaped brain cells, called astrocytes, may be responsible for the rapid improvement in mood in depressed patients after acute sleep deprivation. This in vivo study, published in the current issue of Translational Psychiatry, identified how astrocytes regulate a neurotransmitter involved in sleep.

Scientists wrestle to understand why Huntington's can produce variable symptoms

Scientists have wrestled to understand why Huntington's disease, which is caused by a single gene mutation, can produce such variable symptoms. An authoritative review by a group of leading experts summarizes the progress relating cell loss in the striatum and cerebral cortex to symptom profile in Huntington's disease, suggesting a possible direction for developing targeted therapies.

New insight into structure of Cathepsin B protein

Using the world's most powerful X-ray free-electron laser, an international team of researchers, including scientists of the Max Planck Institute for Medical Research in Heidelberg, has obtained new insight into the structure of a medicinally important protein that may serve as a blueprint for the development of drugs to fight sleeping sickness. Science magazine have chosen the experimental study as one of the top ten scientific breakthroughs of the year.

Researchers track adipose tissue-derived stromal cells after transplantation

Using mesenchymal stromal cells derived from adipose (fat) tissues, genetically modified to express a bioluminescent marker, researchers in Italy have tracked cells after transplantation. The cells were followed from their injection into the spleen of mice modeling liver disease, to their characterization as "hepatic precursors," and to their subsequent migration through the spleen before engrafting at regenerating sites in the liver by bioluminescent imaging.
