OPA1 haploinsufficiency induces a BNIP3‐dependent decrease in mitophagy in neurons: relevance to Dominant Optic Atrophy

Abstract excerpt

Dominant optic atrophy (DOA) is because of mutations in the mitochondrial protein OPA1. The disease principally affects retinal ganglion cells, whose axons degenerate leading to vision impairments, and sometimes other neuronal phenotypes. The exact mechanisms underlying DOA pathogenesis are not known. We previously demonstrated that the main role of OPA1, as a mitochondrial fusogenic and anti-apoptotic protein,...
