To better define cochlear changes associated with hearing loss in NF2-SWN, immunohistochemical cell type markers were used on archival postmortem temporal bone samples from both NF2-SWN patients and healthy controls and quantified the number and cellular density of neural (TUJ1), glial (SOX10), and immune cells (IBA1) within apical, middle, and basal turns of the cochlea. The gene discussed is NF2; the disease is hearing loss disorder.
