Immune system cells protect against CMV-induced hearing loss in mice

A recent study has found that natural killer cells play an important role in protecting against CMV-induced hearing loss in mice. The interaction between NK cells and the viral protein m157 is crucial in preventing hearing loss, with mice lacking this interaction being more susceptible to hearing loss.
