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.
System could provide fine-scale meshes for growing highly uniform cultures of cells with desired properties.
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.
