(B) Immunofluorescent images of cultured OLs, after infection with the indicated lentiviruses and fixation as in A. (C) Quantified data from B reveal that Zdhhc9 knockdown reduces the percentage of GFP-expressing (virally infected) MBP+ cells i.e., mature OLs (**p=0.0067, t-test, n=4 individual cultures per condition). Here, ZDHHC9 is linked to infection.
