Adults expressing LrrkUAS.cIa under the control of Scer\GAL4Fer2.2359 or Scer\GAL4GMR58E02 show a progressive decrease in the number of PAM neurons.

The expression of LrrkScer\UAS.cIa under the control of Scer\GAL4da.G32 leads to a significant increase in the number of type Ib synaptic boutons at the third instar larval neuromuscular junction, as compared to controls.

Expression of LrrkScer\UAS.cIa under the control of Scer\GAL4Mhc.PW, Scer\GAL4G14 or Scer\GAL4how-24B does not result in any significant difference in amplitude of miniature excitatory junction currents (mEJCs), but does lead to an increase in amplitude of EJCs, and an increase in quantal content of larval neuromuscular junctions, and these phenotypes are present over a range of external calcium concentrations, as compared to controls. Expression of LrrkScer\UAS.cIa under the control of Scer\GAL4Mhc.PW leads to a significant increase in the size of the readily releasable pool of vesicles, but no significant difference in quantal size or the probability of vesicle release over a range of external calcium concentrations, and does not result in a significant difference in number of synaptic boutons or presynaptic release sites, as compared to controls.

Flies expressing LrrkScer\UAS.cIa under the control of Scer\GAL4ple.PG do not show a progressive reduction in electroretinogram amplitude (there is no significant difference in the amplitude seen in 3 and 28 day old flies).

Pre-synaptic or post-synaptic expression of LrrkScer\UAS.cIa (under the control of either Scer\GAL4elav-C155 or Scer\GAL4Mhc.PW) results in an estimated 20% decrease in the total number of type I boutons and neuromuscular junction branch number on muscle 6/7 of A3, with no observable effect on muscle size. Neuromuscular length is normal.

The number of dopaminergic neurons in the protocerebral posterior medial 1 and 2 clusters and in the protocerebral posterior lateral 1 cluster and the number of neurons in the protocerebral posterior medial 3 cluster is normal in 60 day old adults expressing LrrkY1383C.Scer\UAS under the control of Scer\GAL4ple.PF.

The expression of LrrkScer\UAS.cIa under the control of Scer\GAL4da.G32 in a Vps35MH20 heterozygous background suppresses the increased number of type Ib synaptic boutons observed in the third instar larval neuromuscular junction of either Vps35MH20 heterozygotes or upon expression of LrrkScer\UAS.cIa under the control of Scer\GAL4da.G32.

eIF4E1S058911/+, TorΔP/+, Fur1rL205/+ or S6kl-1/+ suppresses the increase in excitatory junction current amplitude and quantal content seen in larvae NMJs expressing LrrkScer\UAS.cIa under the control of Scer\GAL4Mhc.PW.

Co-expression of Fur1JF01855 suppresses the increase in excitatory junction current amplitude and quantal content seen in larvae NMJs expressing LrrkScer\UAS.cIa under the control of Scer\GAL4Mhc.PW.

The dot-like small eye phenotype characteristic for flies expressing egrScer\UAS.cMa under the control of Scer\GAL4GMR.PFa is partially suppressed by co-expression of LrrkScer\UAS.cIa.

The severity of the eye defects caused by expression of foxoScer\UAS.cKb under the control of Scer\GAL4GMR.PF are enhanced by co-expression of LrrkScer\UAS.cIa.

Co-expression of foxoScer\UAS.cKb and LrrkScer\UAS.cIa under the control of Scer\GAL4elav.Switch.PO in the presence of RU486 throughout the lifespan has no effect on lifespan. These flies show an age-dependent decrease in the number of PPM1/2, PPM3 and PPL1 neurons.

The reduction of neuromuscular junctions caused by post-synaptic expression of LrrkScer\UAS.cIa (under the control of Scer\GAL4Mhc.PW) is fully suppresses by the coexpression of ThorScer\UAS.cMa.

Coexpression of ThorScer\UAS.cMa in the post-synaptic compartment under the control of Scer\GAL4Mhc.PW is unable to rescue the neuromuscular junction phenotype caused by presynaptic LrrkScer\UAS.cIa expression (under the control of Scer\GAL4elav-C155.

The reduction of neuromuscular junctions caused by post-synaptic expression of LrrkScer\UAS.cIa (under the control of Scer\GAL4Mhc.PW) is unaffected by the coexpression of ThorTA.Scer\UAS.

Coexpression of ThorTA.Scer\UAS in the post-synaptic compartment under the control of Scer\GAL4Mhc.PW is unable to rescue the neuromuscular junction phenotype caused by presynaptic LrrkScer\UAS.cIa expression (under the control of Scer\GAL4elav-C155.

Statement
Reference

Co-expression of Hsap\LRRK2G2019S.Scer\UAS, but not Hsap\LRRK2Scer\UAS.cVa, suppresses the increase in excitatory junction current amplitude and quantal content seen in larvae NMJs expressing LrrkScer\UAS.cIa under the control of Scer\GAL4Mhc.PW.

Complementation and Rescue Data
Comments

Muscle expression of LrrkScer\UAS.cIa (under the control of Scer\GAL4Mhc.PW) rescues the synaptic morphology phenotype and average bouton size found in Lrrke03680 homozygous mutants.

Neuronal expression of LrrkScer\UAS.cIa (under the control of Scer\GAL4elav-C155 results in a partial but still significant rescue of synaptic morphology and average bouton size in Lrrke03680 mutants.

Muscle expression of LrrkScer\UAS.cIa (through Scer\GAL4Mhc.PW) fails to rescue the alterations of mEJC frequency, EJC amplitude, or quantal content in Lrrke03680 mutants.

Neuronal expression of LrrkScer\UAS.cIa (through Scer\GAL4elav-C155) partially rescues EJC amplitude in Lrrke03680 mutants, but fails to significantly rescue quantal content.
