Expression of PGRP-LCScer\UAS.LCx.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4VGlut-OK371 leads to a small but significant increase in the spontaneous miniature excitatory postsynaptic potential amplitude, but not of the excitatory postsynaptic potential, in third instar larval neuromuscular junctions, as compared to controls; expression under the control of Scer\GAL4Mhc.PW leads to decreased spontaneous miniature excitatory postsynaptic potential amplitude and decreased excitatory postsynaptic potential amplitude in third instar larval neuromuscular junctions, as compared to controls.
Expression of PGRP-LCScer\UAS.LCx.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4Mhc.PW, but not of Scer\GAL4VGlut-OK371, results in significantly decreased muscle input resistance and decreased negative resting membrane potential in third instar larval neuromuscular junctions, as compared to controls.
Scer\GAL4elav-C155/PGRP-LCUAS.LCx.Venus partially rescues PGRP-LCΔE
Scer\GAL4VGlut1-OK371/PGRP-LCUAS.LCx.Venus partially rescues PGRP-LCΔE
PGRP-LCUAS.LCx.Venus/Scer\GAL4Mhc.PW fails to rescue PGRP-LCΔE
Expression of PGRP-LCScer\UAS.LCx.T:Avic\GFP-YFP.Venus under the control of either Scer\GAL4elav-C155 or Scer\GAL4VGlut-OK371, but not of Scer\GAL4Mhc.PW, rescues the decreased spontaneous miniature excitatory postsynaptic potential observed in neuromuscular junctions of PGRP-LCΔE homozygous mutant third instar larvae; expression of PGRP-LCScer\UAS.LCx.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4elav-C155, but not of Scer\GAL4VGlut-OK371 or Scer\GAL4Mhc.PW, also rescues the decreased excitatory postsynaptic potential observed in neuromuscular junctions of PGRP-LCΔE homozygous mutant third instar larvae.
