This is particularly interesting given that in the rat, upon cochlear ablation, the DCN displays an acute neuroinflammatory reaction mainly in its surface facing the ventricle (Perin et al., 2017), rather than in its deep layer receiving cochlear nerve fibers (Trussell and Oertel, 2017), and that CP trafficking of macrophages is observed after stroke (Ge et al., 2017) and spinal cord injury (Shechter et al., 2013). The gene discussed is CP; the disease is stroke disorder.
