OPA1 in Cardiovascular Health and Disease

Mitochondria are known to play crucial roles in normal cellular physiology and in more recent years they have been implicated in a wide range of pathologies. Central to both these roles is their ability to alter their shape interchangeably between two different morphologies: an elongated interconnected network and a fragmented discrete phenotype - processes which are under the regulation of the mitochondrial fusion and fission proteins, respectively. In this review article, we focus on the mitochondrial fusion protein optic atrophy protein 1 (OPA1) in cardiovascular health and disease and we explore its role as a potential therapeutic target for treating cardiovascular and metabolic disease.
