Overexpression of snapinScer\UAS.cDa in the nervous system under the control of Scer\GAL4elav-C155 does not potentiate synaptic transmission.
Co-expression of SnapinScer\UAS.cDa in motorneurons (under the control of Scer\GAL4VGlut-OK371) in Dysbe01028; Df(2L)Exel6277 double heterozygotes restores homeostasis towards control levels (although this rescue is not complete).
The presynaptic homeostatic plasticity that normally occurs after application of the postsynaptic glutamate receptor antagonist PhTx is blocked in Snap25124/+ ; Df(2L)Exel6277/+ double heterozygous larvae. Synaptic homeostasis can be restored in the double heterozygotes through expression of SnapinScer\UAS.cDa in the motorneurons (under the control of Scer\GAL4elav-C155).
