Furthermore, as a symbol of retinal dystrophy, retina inflammation, which was characterized with the activation of GFAP‐positive glia cells,28, 29 was prominent, as revealed by retina frozen section IF staining and WB using GFAP antibody in KO mice (Figure 6B), suggesting that inflammation played a role in Tmem184b KO‐induced retina degenerating process. Here, GFAP is linked to inherited retinal dystrophy.
