ADSL and infection: As our results indicated that AMPs, especially Diptericins play a key role in Drosophila priming against P. rettgeri, we wanted to test if the priming effect we had observed was a result of constant upregulation of AMPs after initial heat-killed exposure allowing rapid bacterial clearance during the secondary exposure, or if AMP expression returned to a baseline level within the 96-hours between priming and the live infection.
