Abstract: Adiponectin receptor 1 (AdipoR1) and Adiponectin receptor 2 (AdipoR2) can bind to adiponectin (AdipoQ) secreted by adipose tissue to participate in various physiological functions of the body. In order to explore the role of AdipoR1 and AdipoR2 in amphibians infected by Aeromonas hydrophila (Ah), the genes adipor1 and adipor2 of Rana dybowskii were cloned by reverse transcription-polymerase chain reaction (RT-PCR) and analyzed by bioinformatics. The tissue expression difference of adipor1 and adipor2 was analyzed by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR), and an inflammatory model of R. dybowskii infected by Ah was constructed. The histopathological changes were observed by hematoxylin-eosin staining (HE staining); the expression profiles of adipor1 and adipor2 after infection were dynamically detected by qRT-PCR and Western blotting. The results show that AdipoR1 and AdipoR2 are cell membrane proteins with seven transmembrane domains. Phylogenetic tree also shows that AdipoR1 and AdipoR2 cluster with the amphibians in the same branch. qRT-PCR and Western blotting results show that adipor1 and adipor2 were up-regulated at different levels of transcription and translation upon Ah infection, but the response time and level were different. It is speculated that AdipoR1 and AdipoR2 participate in the process of bacterial immune response, providing a basis for further exploring the biological functions of AdipoR1 and AdipoR2 in amphibians.
