MYO15A and infection: As shown in Fig. 4D and E, in the AAV-PHP.eB-mini-Myo15-GFP group, GFP was exclusively expressed in HCs (colabeled by phalloidin), while the AAV-PHP.eB-CMV-GFP group showed a broad infection pattern and GFP was expressed in various cell types, including HCs, the lateral wall, the spiral limbus, the spiral ganglion, and the stria vascularis.
