"In
lin-6(
e1466) L4 larvae, SNB-1-CFP was detected only in the dorsal cord, confirming that DDs rewired properly, and, as expected, no GABA innervation was observed ventrally (Fig. 3A). UNC-49-YFP clusters colocalized with presynaptic varicosities along the dorsal cord (Fig. 3A,B). However, in ventral muscle cells, UNC-49-YFP clusters were absent, and only scattered YFP fluorescence was detected in some cells (Fig. 3B)."
