Most autophagy-deficient mice are lethal embryonic or at the early postnatal stages. This reflects the importance of autophagy for development and differentiation. One of our main scientific interests is to understand how autophagy regulates the development of the nervous system using the retina as a model. Our group has shown that autophagy is necessary for neuronal differentiation and for the removal of apoptotic cells that occur during normal development of the nervous system. In addition, we have evidence that autophagy may have a metabolic role allowing ATP to be obtained through the degradation of cellular components.
In addition, we have shown that selective mitochondrial degradation, a process known as mitophagy, regulates metabolic reprogramming during neuronal differentiation and is an essential processes for neuronal differentiation. In addition, this role of mitophagy in regulating the metabolism seems universal since it is also observed during the polarization of macrophages to a proinflammatory phenotype. Therefore my research points to a new metabolic role of autophagy during cellular development and differentiation and we hope to understand in precise molecular mechanism in the future.
