Fig. 9. Localization of RAB-3 in the nervous system. Animals were stained with an anti-RAB-3 (α-RAB-3) antibody. DAPI staining shows the cell bodies. Animal genotypes are shown above each panel. In each photograph, the ventral nerve cord is at the bottom. In both wild-type and cab-1 mutants, RAB-3 immunoreactivity was restricted primarily to the ventral cord where many neuromuscular synapses are found. In contrast, in aex-3 animals much of the RAB-3 immunoreactivity was located in neural cell bodies.
