Defence reaction against nematobacterial infection in Drosophila melanogaster: a role for the adipokinetic hormone and adenosine

Popis výsledku v původním jazyce

Entomopathogenic nematodes are multicellular insect parasites which are symbiotically associated with particular species of bacteria forming together highly pathogenic complex. This complex represents a severe stress for the infected insect that must activate its anti-stress defence system. It is supposed that adipokinetic hormone (AKH), important stress hormone responsible for keeping homeostasis in insect body, and adenosine, a purine nucleotide that serves as signalling factor in anti-stress reaction on both cellular and organismal levels, play a role in defence reaction against the infection. To verify this, the Drosophila melanogaster mutants producing (1) defect non-functional AKH (AKH-def) and (2) impaired adenosine receptor (AdoR-def), and two nematodal species Steinernema carpocapsae and Heterorhabditis bacteriophora were used in our study. The results revealed that both AKH-def and AdoR-def flies infected by the nematodes showed significantly lower mortality (1.9 and 1.
