University College Dublin Researchers Discover Cell Messaging System for Targeting Tumors
Researchers at University College Dublin have identified a novel 'courier system' that cells use to transmit coherent biological messages, potentially revolutionizing medicine and biotechnology. This discovery, published in Nature Materials, reveals that certain nanoparticles entering a cell can transform and acquire a 'condensate corona,' a coating made from the cell's proteins and RNA. This coating acts as a biological program, allowing the nanoparticles to deliver messages to other cells. The research team, led by Professor Kenneth Dawson and Associate Professor Yan Yan, found that these messaging droplets can be captured in transit using tiny magnets, preserving the integrity of the messages. Once inside a new cell, the coating detaches and avoids the cell's degradation system, allowing the proteins and RNA to integrate into the cell's processes. This system could enable the delivery of therapeutic biomolecules to previously inaccessible areas within cells, enhancing the effectiveness and safety of RNA...
