After stab injury, almost all RG underneath the injury site respond to the injury by glial reactivation, characterized with the up-regulation of vimentin expression and robust GFP expression in a powerful transgenic line Tg(1016tuba1α:GFP), which has been used to monitor the injury-induced MG in zebrafish retina (Fausett and Goldman, 2006; Wan et al., 2012). Here, VIM is linked to myasthenia gravis.
