Oxidative stress induces overgrowth of the Drosophila neuromuscular junction.

Synaptic terminals are known to expand and contract throughout an animal's life. The physiological constraints and demands that regulate appropriate synaptic growth and connectivity are currently poorly understood. In previous work, we identified a Drosophila model of lysosomal storage disease (LSD), spinster (spin), with larval neuromuscular synapse overgrowth.
