Increased expression of myelin basic protein (MBP) (involved in the process of remyelination) was detected in the BST of HSV-1-infected cotton rats on day 10 post-infection and subsided by day 17 (Figure 3C), the time by which most animals recovered from facial palsy, suggesting that remyelination may aid recovery from facial palsy. This evidence concerns the gene MBP and Facial palsy.
