JEDDAH: Scientists at King Abdullah University of Science and Technology have engineered nanoscale particles capable of transporting six proteins into living cells, where they work together as a miniature “drug factory” to produce violacein, a bioactive compound under study for therapeutic use. The findings, detailed in a news release published on KAUST’s news site, offer an early demonstration of how future therapies might one day generate treatment compounds directly inside the body, only where they are needed.
