In “proof of concept” experiments with mouse and human cells and tissues, Johns Hopkins Medicine researchers say they have designed tiny proteins, called nanobodies, derived from llama antibodies, that could potentially be used to deliver targeted medicines to human muscle cells. The researchers say the ability to more precisely target such tissues could advance the search for safer, more efficient ways to alleviate pain during surgery, treat irregular heart rhythms and control seizures.
