Inflammatory cytokines are involved in the development of mucus cell metaplasia/hyperplasia (MCM) in otitis media (OM). However, which cytokines play an essential role in MCM OM is not clear at the moment. In this study, we hypothesized that interleukin-10 (IL-10) played an indispensable role in MCM of bacterial OM and used IL-10 knockout mice to test this hypothesis. In wild-type mice, both S. pneumoniae and H. influenzae triggered the development of MCM in the middle ear mucosa. In IL-10 knockout mice, the number of goblet cells and mucin-producing cells in the middle ear was significantly reduced after bacterial middle ear infection compared with that in wild-type mice. We, therefore, concluded that IL-10 plays an essential role in MCM of bacterial OM. IL-10 is a potential target for the treatment of MCM in OM.
