Axons from Scer\GAL4VT039046 expressing neurons terminate in the adult subesophageal zone with their dendritic compartments located near the pars intercerebralis and esophagus. Positive GRASP (GFP reconstitution across synaptic partners) signals between adult Hugin neurons labelled with Ecol\lexAGMR61H10 and DH44 neurons labelled with Scer\GAL4VT039046 were observed in the adult subesophageal zone, near the esophagus, and along the midline of the brain.
Scer\GAL4VT039046 drives expression in a subset of six Scer\GAL4Kurs58 positive neurons of the adult pars intercerebralis (PI) recapitulating endogenous Dh44 protein expression. GFP reconstitution across synaptic partners (GRASP) shows a connection between Scer\GAL4VT039046 positive PI neurons and Ecol\lexAClk.4.1M.T:Hsim\VP16 positive DN1p neurons.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 28[o]C) of Scer\GAL4VT039046 neurons in adults results in a significant reduction in the strength of circadian locomotor rhythms, compared to controls.
