    Mitochondrial fusion but not fission regulates larval growth and synaptic development through steroid hormone production

    Hector Sandoval, Chi-Kuang Yao ... Hugo J Bellen
    The dual role of Drosophila Mitofusin in steroid hormone production and cholesterol ester storage, which is evolutionary conserved by the combined expression of the two mammalian Mitofusins, ensures proper synaptic development.
