Abstract: This study aims to reveal the interaction mechanism between the pathogen and the midgut cells by analyzing the differential expressed proteome of the midgut after Apis mellifera worker infected with/without Vairimorpha ceranae(Nosema ceranae). The 5-day old workers were fed ad lib with sucrose solution containing 104spore·μL-1 for 48 h, then raised in the incubator under 30℃ for 18 days(23 days old). The results showed that the survival rate of workers in infected group was only 34.81%, which was significantly lower than that of the control, 71.85% (P<0.05). The midgut protein concentration was significantly decreased either (P<0.05), however, there was no significant difference in the daily consumption of sucrose solution per bee (P>0.05). The comparison of the midgut proteomes of the infected bee and the control by using tandem mass tags (TMT) showed that, 565 proteins were significantly differentially expressed, in which 301 proteins were up-regulated and 264 proteins were down-regulated in the infected midgut. The enrichment of different protein GO functional annotations showed that the cell process, energy metabolism, cell morphology, protein complexes, molecular binding, and catalytic activity in the infected midgut cells were significantly affected. Through the enrichment of the KEGG pathway, it was found that aminoacyl-tRNA biosynthesis, protein processing in the endoplasmic reticulum, and various types of N-glycan biosynthesis were significantly up-regulated, as well as some antioxidant proteins. The proteins enriched in amino acid metabolism and sucrose metabolic pathways were significantly down-regulated. It was revealed that the infection of V.ceranae at late stage significantly compromised the protein expression relatived to the digestion and immunity. These significant differential proteins provides a strong support for the subsequent screening and verification of interaction proteins between V. ceranae and A. mellifera.
