This study intends to characterize the sialotranscriptome profile of in response to and identify genes of interest with differential genomic expression, indicating relevant targets in the tick-protozoan interactions. The experimental design consisted of RNA sequencing from uninfected and -infected salivary glands (SGs) to obtain transcriptomic profiles for characterization and comparison. A total of 288,952 transcripts were obtained from both tick profiles, 3456 transcripts ( < 0.05) differentially expressed in response to infection. The uninfected SGs' registered 231,179 transcripts, of which 155,359 were annotated. The most transcribed sequences were female-specific histamine binding protein and lipocalins. Regarding the -infected SGs, from the 238,964 assembled transcripts, 163,564 were annotated. The most transcribed sequences were histone demethylase JARID1 and Y-box-binding protein. Five transcripts (cystatin, arginase, nuclear factor κB kinase inhibitor subunit β (IκB), IκB delta, lysosomal-trafficking regulator, and reeler protein) presented the gene ontology (GO) category "response to protozoan" and were exclusively displayed in the -infected profile. The transcriptome of was also analyzed, registering 4728 hits. The study's genetic and molecular information would be of great value for future studies and biotechnological applications envisaging disease control.
本研究旨在表征 对 的唾液转录组谱,并鉴定具有差异基因组表达的感兴趣基因,以表明蜱-原生动物相互作用中的相关靶点。实验设计包括对未感染和 感染的蜱唾液腺(SGs)进行RNA测序,以获得用于表征和比较的转录组谱。从两种蜱的谱中总共获得了288,952个转录本,其中3456个转录本(<0.05)在 感染后差异表达。未感染的SGs记录了231,179个转录本,其中155,359个被注释。转录最多的序列是雌性特异性组胺结合蛋白和脂质运载蛋白。关于 感染的SGs,在238,964个组装转录本中,163,564个被注释。转录最多的序列是组蛋白去甲基化酶JARID1和Y盒结合蛋白。五个转录本(胱抑素、精氨酸酶、核因子κB激酶抑制剂亚基β(IκB)、IκBδ、溶酶体运输调节因子和reeler蛋白)呈现基因本体(GO)类别“对原生动物的反应”,并且仅在 感染的谱中显示。还分析了 的转录组,记录了4728个命中。该研究的遗传和分子信息对于未来设想疾病控制的研究和生物技术应用具有重要价值。
