In proof-of-concept experiments, researchers at University of California, San Diego School of Medicine demonstrate the ability to tune medically relevant cell behaviors by manipulating a key hub in cell communication networks. The manipulation of this communication node, reported in this week’s issue of Proceedings of the National Academy of Sciences, makes it possible to reprogram large parts of a cell’s signaling network instead of targeting only a single receptor or cell signaling pathway. …Read the full story from the UC San Diego Newsroom
Researchers show B cells can deliver potentially therapeutic bits of modified RNA
Researchers at the University of California, San Diego School of Medicine have successfully targeted T lymphocytes – which play a central role in the body’s immune response – with another type of white blood cell engineered to synthesize and deliver bits of non-coding RNA or microRNA (miRNA). … Read the full story from the UC San Diego News Center
