Spatially patterned mitochondrial remodeling in zebrafish Muller glia begins in inner retinal compartments before sustained mitochondrial volume increases near injured photoreceptors, during regenerative activation after photoreceptor loss.
- Why it matters: The timing and organization of mitochondrial changes that accompany Muller glia reprogramming and regeneration are not well defined, limiting understanding of how metabolic remodeling supports retinal repair.
- What they did: Using a Muller glial mitochondrial reporter, Muller glial transcriptomics, and whole eyecup metabolomics after selective photoreceptor loss, the study mapped spatial-temporal mitochondrial morphology and gene/metabolite shifts; it also tested dichloroacetate (DCA) to inhibit PDK.
- The result: DCA attenuated outer-retinal mitochondrial remodeling, reshaped injury-linked transcription, and blocked tuba1a:GFP+ Muller glia formation and PCNA expression, indicating PDK/PDH regulatory activity is required for reprogramming and progenitor proliferation.
