Deletion of part of the ple sequence.
ScerGAL4ple.TH-C' drives expression in a subset of ple-positive dopaminergic neurons in the adult brain as well as in the thorax and abdomen.
ScerGAL4ple.TH-C' drives expression in 5 or fewer dopaminergic neurons in each cluster where it is expressed.
ScerGAL4ple.TH-C' drives expression in a subset of the dopaminergic neurons in the adult brain labelled by ScerGAL4ple.PF : around 3 PAL neurons, 5 PPM2 neurons and 6 PPL2 neurons. There was also some non-systematic expression in less than 1 neuron in the PAM and PPM1 clusters.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 32[o]C) of a subset of Scer\GAL4ple.TH-C' cells (activation restricted using Scer\GAL80ple.TH-F) in adults in combination with a paired odor, does not result in any significant short-term associative olfactory memory, compared to controls; activation of this subset specifically during odor-stimulus pairing and not other time intervals significantly increases aversive, but not appetitive, short-term associative olfactory memory, compared to controls, and this enhancement is lost when activation is further restricted using Scer\GAL80ple.PU.
Inhibition (using shits.UAS.cUa at 32[o]C) of a subset of Scer\GAL4ple.TH-C' cells (activation restricted using Scer\GAL80ple.TH-F) in adults does not significantly affect short-term aversive of attractive associative olfactory memory, compared to controls.
Inhibition (using shi1.UAS at 32[o]C) of Scer\GAL4ple.TH-C' cells in adults does not affect startle-induced climbing behavior, compared to controls.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 32[o]C) of Scer\GAL4ple.TH-C' cells in adults significantly reduces startle-induced climbing behavior, compared to controls.
Inhibition (using shi1.UAS at 29[o]C) of Scer\GAL4ple.TH-C' cells in adults significantly reduces the number of animals capable of flight, compared to controls; animals that do not fly have significant wing coordination defects, compared to controls; there is also a significant reduction in the duration of electrophysiological spiking in dorsal longitudinal indirect flight muscles in response to an air puff, compared to controls.
Inhibition (using Hsap\KCNJ2UAS.EGFP) of Scer\GAL4ple.TH-C' cells, in combination with a Gal80[ts] transgene to restrict expression to the adult stage, significantly reduces the number of animals capable of flight, compared to controls; there is also a significant reduction in the number of animals that display electrophysiological spiking in dorsal longitudinal indirect flight muscles in response to an air puff, compared to controls.
Inhibition (using Hsap\KCNJ2UAS.EGFP) of Scer\GAL4ple.TH-C' cells, in combination with a Gal80[ts] transgene to restrict expression to the adult stage, does not affect aversive shock or temperature olfactory memory, compared to controls.
