The first set (19.02.2026):

The two sets pooled:

stressor: cold (18°C; 48h)

control group: Pos_CTRL

experimental group: Gr28bd+TrpA1(cold)

stressor: Sleep deprivation (24h, room temperature)

POS_CTRL: control group

Gr28bd+TrpA1(sleep): experimental group

Generation of TurboID-linker-aPKC construct

On the left, there are the results of the experimental group: social isolation, with the usual R Skript. The right side shows the same results but with an adjusted “flat threshold” (for movement) of 0.4 instead of 0.9.

First Feeding essay for experimental group “crowding” and “sleep deprivation”:

stressor: heat (37°C; 6min)

POS_CTRL: control group

Gr28bd+TrpA1(heat): experimental group

10 flies completed out of 36 flies.

For the stressor ‘cold’ the flies were kept on 18°C for 48h on ATR.

stressor: cold (18°C for 48h)

POS_CTRL: control group

Gr28bd+TrpA1(cold): experimental group

For the stressor ‘crowding’ ca. 60-65 flies were kept in one vial for 48h on ATR.

The effect of crowding was created by the volume of air available to the flies in the vial. This was altered via change in the height of the cotton plug in the vial. The control group had the cotton plug at the usual height of ca. 60mm above the food in the vial and the experimental group only 20mm.

stressor: crowding (maintained in smaller volume for 48h on ATR)

POS_CTRL: control group

Gr28bd+TrpA1(Crow): experimental group
