Deletion of Transmembrane protein 184b leads to retina degeneration in mice.

ABSTRACT: Transmembrane protein 184b (Tmem184b) has been implicated in axon degeneration and neuromuscular junction dysfunction. Notably, Tmem184b exhibits high expression levels in the retina; however, its specific function within this tissue remains poorly understood. To elucidate the role of Tmem184b in the mammalian visual system, we developed a Tmem184b knockout (KO) model for further investigation. Loss of Tmem184b led to significant decreases in both a and b wave amplitudes of scotopic electroretinogram (ERG) and reduced b wave amplitudes of photopic ERG, respectively, reflecting damage to both the photoreceptors and secondary neuronal cells of the retina. Histologic analyses showed a progressive retinal thinning accompanied by the significantly loss of retinal cells including cone, rod, bipo
