Absence of perisynaptic glia at larval body wall neuromuscular synapses.

Confocal immunofluorescence images of larval neuromuscular synapses as described in Fig 1 (A) In WT, GS2 is associated with non-synaptic regions of motor axons but does not extend to fine axon branches which form synapses. (B) Gs2-RNAi KD using moody-GAL4 largely eliminated the GS2 signal at larval neuromuscular synapses and did not reveal the presence of a perisynaptic glial cell type.
