Early sleep loss accelerates Alzheimer’s pathology in mice

Lack of sleep during adolescence and early adulthood accelerates Alzheimer’s disease (AD)-related tau pathology, finds a study of male and female mice published in JNeurosci. These results support the importance of establishing healthy sleep habits in early adult life to help stave off progression of neurodegenerative diseases. Using a mouse model of tauopathy, Sigrid Veasey […]

New model mimics human tumors for accurate testing of cancer drugs

Walter and Eliza Hall Institute researchers have genetically engineered a new laboratory model that enables accurate testing of anti-cancer drugs by mimicking the complexity of human cancers. Using this advanced model, researchers will be able to discover the safest and most effective ways to use promising drugs called MCL-1 inhibitors in the clinic. The work […]

Satiety in 3-D

Many overweight people lack the feeling of being full. It was long thought that this was due to the disrupted transport of the satiety hormone leptin to the brain. That is not the case, as a group of scientists from Helmholtz Zentrum München has now shown in the International Journal of Obesity. The work was […]

Creating custom brains from the ground up

Scientists studying how genetics impact brain disease have long sought a better experimental model. Cultures of genetically-modified cell lines can reveal some clues to how certain genes influence the development of psychiatric disorders and brain cancers. But such models cannot offer the true-to-form look at brain function that can be provided by genetically-modified mice. Even […]
