Professor Sachie Hiratsuka of the Institute for Biomedical Sciences/Department of Biochemistry and Molecular Biology at Shinshu University School of Medicine has newly discovered that extracellular messenger RNA (mRNA) of a particular sequence binds to receptors on the surface of natural killer (NK) cells and becomes internalized into the nucleus. This novel mRNA uptake leads to increased NK-cell migration activity and interferon-γ production. Moreover, NK cells that took up the extracellular mRNA were found to inhibit the spread of cancer in animal studies.
The findings were published online in Nature Communications of Springer Nature journal.
