Fly models of lysosomal storage diseases (LSDs) exhibit diminished synaptic growth
Lysosomal protein degradation and MTORC1 activation promote synaptic growth via JNK
MTORC1 phosphorylates Wallenda/DLK1, an MAPKKK upstream of JNK in flies and mammals
ALK inhibition along with high protein diet restores synaptic growth in LSD models
