Results for Dop1R1-RNAi, Amon-RNAi and the course data

on Tuesday, May 21st, 2024 8:11 | by

Firstly, I did an experiment where Dop1R1 was knocked down via RNAi. The following shows the results:

For the next experiment, the controls groups were the same, however in the experimental group Amon was down regulated. These are the results:

Lastly, in the course the data for the larvae experiment was collected only under blue light, so I used the same crossings and tested them under red light to use as a control.

All figures show the results for preference tests (salt/pure) conducted under red and blue light for different gal4-lines.

Results for amon-RNAi and MB143B

The first figure shows the results for the preference test (salt/pure) conducted with amon-RNAi only under red light.

For the next experiment I conducted the same preference test but with the split-gal4 line MB143B under red and blue light.

Results for MB+DANs and MB054B

The first experiment tested the activation of KCs with simultaneous ablation of pPAM which showed the following results:

Green: UAS-ChR2-XXL; LexAop-rpr x 58E02-LexA; H24-Gal4

Lightgrey: UAS-ChR2-XXL; LexAop-rpr x H24-Gal4

Darkgrey: UAS-ChR2-XXL x 58E02-LexA; H24-Gal4

The next experiment was conducted with the split-Gal4 line MB054B (DAN-f1/DAN-g1) and showed the following:

Confocal images with anti-GFP and anti-Brp staining of TH-C-AD;TH-D-DBD > mCD::GFP fly brains: A: 4 PPM 2 DANs per hemisphere marked with blue circles, three clusters of Kenyon cell bodies per hemisphere marked with white arrows. B: Five visible cell bodies of unidentified neurons marked with a blue circle in the left hemisphere. The neurons project into the lobula plate and the medulla. Strong fluorescence of cell bodies of the Kenyon cells projecting into the Mushroom bodies is visible. C: Unidentified neurons projecting into structures outside of the optic lobes especially the ventral lateral protocerebrum.

Optogenetic stimulation of DANs

With the focus on dopaminergic neurons, I conducted two experiments with two different driver lines to see how the naive gustatory behavior in Drosophila larvae is affected.

The first cross I tested was R58E02-Gal4 x UAS-ChR2-XXL, which gave me the following results:

As seen in the figures, there was no effect under blue light.

For the second experiment I crossed TH-Gal4 x UAS-ChR2-XXL with these results:

With this experiment, there was an effect on gustatory behavior as there is a clear significant difference between the experimental group and the control group.

Preferences with higher salt concentration

The following plots show the results after I increased the salt concentration from 1,5M to 2,5M. It shows that the difference between the control groups and experimental group are not significant anymore.
