Expression of GluRIICdsRNA.Scer\UAS.cBa driven simultaneously by Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57 significantly diminishes miniature excitatory postsynaptic potential (mEPSP) amplitudes (decreasing quantal size), leading to significant homeostatic compensatory increases in quantal content at the neuromuscular junction (NMJ) of third instar larvae, compared to controls.

Larvae expressing GluRIICdsRNA.Scer\UAS.cBa under the control of Scer\GAL4C57 show a decrease in spontaneous miniature neurotransmission. A compensatory increase in quantal content means that evoked neurotransmission is unaffected.

When female flies expressing GluRIICdsRNA.Scer\UAS.cBa under the control of multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57) (aka T15 flies) are crossed to wild type males the resulting larvae exhibit defects in spontaneous neurotransmission. A compensatory increase in quantal content means that evoked neurotransmission is unaffected. When T15 males are crossed to wild type females neurotransmission is similar to controls. Synapse growth and morphology are grossly normal.

Expression of GluRIICdsRNA.Scer\UAS in muscle throughout development (under the control of Scer\GAL4C57) causes a reduction in mEJP amplitude and a homeostatic increase in presynaptic release.

Third instar larvae with co-expression of GluRIICdsRNA.Scer\UAS.cBa and CskGD9345 driven simultaneously by Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57 show significant decreases in mEPSP (decreasing quantal size) but do not show significant compensatory homeostatic increases in quantal content (as seen with expression of GluRIICdsRNA.Scer\UAS.cBa alone) at the NMJ; larvae with co-expression show diminished evoked muscle excitation compared to larvae with expression of GluRIICdsRNA.Scer\UAS.cBa alone.

Third instar larvae with co-expression of GluRIICdsRNA.Scer\UAS.cBa and CskScer\UAS.T:Avic\GFP-YFP driven simultaneously by Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57 show significant decreases in mEPSP (decreasing quantal size) and show significant compensatory homeostatic increases in quantal content (as seen with expression of GluRIICdsRNA.Scer\UAS.cBa alone) at the NMJ.

Third instar larvae with co-expression of GluRIICdsRNA.Scer\UAS.cBa and Fas2EP1462 driven simultaneously by Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57 show significant decreases in mEPSP (decreasing quantal size) and show significant (though not complete) impairment of compensatory homeostatic increases in quantal content (compared to quantal content increases seen with expression of GluRIICdsRNA.Scer\UAS.cBa alone) at the NMJ.

Co-expression of Fas2Scer\UAS.cLa, Fas2Scer\UAS.cLb or Fas2C.Scer\UAS in third instar larvae with GluRIICdsRNA.Scer\UAS.cBa simultaneously driven by Scer\GAL4C57 and Scer\GAL4elav-C155 does not impair homeostatic compensation at the neuromuscular junction (significant reduction in mEPSP and significant increase in quantal content compared to controls, just as is seen in larvae with expression of GluRIICdsRNA.Scer\UAS.cBa simultaneously driven by Scer\GAL4C57 and Scer\GAL4elav-C155).

Fas2e76/Y or Fas2e76/Fas2G0293 third instar larvae with GluRIICdsRNA.Scer\UAS.cBa driven by Scer\GAL4C57 do not show impairment of homeostatic compensation at the neuromuscular junction (significant reduction in mEPSP and significant increase in quantal content compared to controls, just as is seen in larvae with expression of GluRIICdsRNA.Scer\UAS.cBa driven by Scer\GAL4C57).

Co-expression of Fas2JF02918 or Fas2GD14486 in third instar larvae with GluRIICdsRNA.Scer\UAS.cBa simultaneously driven by Scer\GAL4C57, Scer\GAL4elav-C155 and Scer\GAL4sca.PC does not impair homeostatic compensation at the neuromuscular junction (significant reduction in mEPSP and significant increase in quantal content compared to controls, just as is seen in larvae with expression of GluRIICdsRNA.Scer\UAS.cBa simultaneously driven by Scer\GAL4C57, Scer\GAL4elav-C155 and Scer\GAL4sca.PC).

Expression of GluRIICdsRNA.Scer\UAS.cBa enhances the reduction in quantal size seen in the larval NMJ when cacKK101478 is expressed in multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57) alone. However, the defects in evoked transmission are not enhanced due to a compensatory increase in presynaptic quantal content.

Expression of CspGD10571 completely prevents the compensatory increase in quantal content seen in response to reduced quantal size when GluRIICdsRNA.Scer\UAS.cBa is expressed using multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57). Evoked neurotransmission is therefore disrupted.

Expression of CspGD10571 does not prevent the compensatory increase in quantal content seen in response to reduced quantal size when GluRIICdsRNA.Scer\UAS.cBa is expressed under the control of Scer\GAL4C57. Evoked neurotransmission is unaffected.

Expression of Plc21CGD11359 prevents the compensatory increase in quantal content seen in response to reduced quantal size when GluRIICdsRNA.Scer\UAS.cBa is expressed using multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57). Evoked neurotransmission is therefore disrupted. Muscle expression of Plc21CGD11359 (under the control of Scer\GAL4C57) do not prevent the compensatory increase and evoked neurotransmission is unaffected.

Expression of Plc21CHMS00600 prevents the compensatory increase in quantal content seen in response to reduced quantal size when GluRIICdsRNA.Scer\UAS.cBa is expressed using multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57).

Expression of Plc21CJF01211 prevents the compensatory increase in quantal content seen in response to reduced quantal size when GluRIICdsRNA.Scer\UAS.cBa is expressed using multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57).

Expression of Plc21CJF01210 prevents the compensatory increase in quantal content seen in response to reduced quantal size when GluRIICdsRNA.Scer\UAS.cBa is expressed using multiple pre- and post-synaptic drivers (Scer\GAL4elav-C155, Scer\GAL4sca.PC and Scer\GAL4C57).

The developmental homeostatic plasticity that normally occurs in larvae expressing GluRIICdsRNA.Scer\UAS.cFa in the muscle under the control of Scer\GAL4C57 is completely blocked if the larvae are also expressing P{GD12574} in the nervous system (under the simultaneous control of both Scer\GAL4elav-C155 and Scer\GAL4sca.PC).
