| Research Abstract |
For clinical application of hearing loss therapy noise-exposed mice were treated with MR16-1 and evaluated. Improved hearing was noted in noise-exposed mice treated with MR16-1. Histological analysis revealed the decrease in spiral ganglion neurons was ameliorated in the MR16-1-treated group. A remarkable reduction of activated cochlear macrophages in spiral ganglions compared to the control group was observed when treated with MR16-1.
Thus, MR16-1 had protective effects both functionally and pathologically for the noise-damaged cochlea. IL-6 blockade would be a feasible novel therapeutic strategy for hearing loss.
