New CRISPR-based map ties every human gene to its function

Jonathan Weissman and collaborators used their single-cell sequencing tool Perturb-seq on every expressed gene in the human genome, linking each to its job in the cell.

Smelling your food makes you fat

Our sense of smell is key to the enjoyment of food, so it may be no surprise that in experiments at the University of California, Berkeley, obese mice who lost their sense of smell also lost weight.

Gene transfer as a treatment of neurodegenerative diseases: Viral vectors travel longer distances than previously thought

Gene transfer is seen as a hopeful therapy for Alzheimer’s and Parkinson’s patients. The approach involves using harmless laboratory-produced viruses to introduce important genes into the brain cells. In a study on mice, a team of researchers from Vetmeduni Vienna for the first time investigated how far these viruses spread in the brain and which cells they infect. Some of the artificial viruses travelled from the injection site in the brain as far as the olfactory bulb or the cerebellum and infected not only neurons but also other cells. The results, which were published in the journal Histochemistry and Cell Biology, could help to improve the selection of suitable viral “gene transporters” for custom therapies using gene transfer.
