Transinfection of bacteria or fungi could substantially alter the expression of host immune system components. However, few studies have focused on the effects of native <i>Wolbachia</i> infection. Accordingly, in this study, we evaluated the proteomics of <i>N. vitripennis</i> following <i>Wolbachia</i> infection.<h4>Methods</h4>We studied the proteomics of <i>N. vitripennis</i> following native <i>Wolbachia</i> infection and in antibiotic-treated <i>Wolbachia</i>-free samples using isobaric tags for relative and absolute quantification-liquid chromatography tandem mass spectrometry, accompanying with some ecological experiments.<h4>Results</h4>In total, 3,096 proteins were found to be associated with a wide range of biological processes, molecular functions, and cellular components. Interestingly, there were few significant changes in immune or reproductive proteins between samples with and without <i>Wolbachia</i> infection. Differentially expressed proteins were involved in the binding process, catalytic activity, and the metabolic process, as confirmed by quantitative reverse transcription polymerase chain reaction.<h4>Discussion</h4>Invasion of any pathogen or bacterium within a short time can cause an immunoreaction in the host. Our results implied that during the long process of coexistence, the immune system of the host was not as sensitive as when the symbiont initially infected the host, implying that the organisms had gradually adjusted to cohabitation.Proteomics of <i>Nasonia vitripennis</i> and the effects of native <i>Wolbachia</i> infection on <i>N. vitripennis</i>.Li Jie J, Wang Ningxin N, Liu Yong Y, Qiu Shiqi SfalseProteomics of Nasonia vitripennisWe studied the proteomics of N. vitripennis with native Wolbachia infection and antibiotics-cured Wolbachia-free samples using iTRAQ-LC-MS/MS.
