Project description:Transcriptional profiling of blood B cells from bovine leukemia virus-infected cattle comparing IgMhigh B cells with IgMlow B cells. Goal was to estimate the difference of cellular function in both subset. Two-condition experiment, IgMhigh B cells vs. IgMlow B cells from three bovine leukemia virus-infected cattle.
Project description:Extracellular vesicles (EVs) are key mediators of intercellular communication, and often play critical roles in host-parasite interactions by facilitating parasite’s physiology and pathogenesis. Theileria annulata, an apicomplexan parasite, induces profound changes in host cells, leading to uncontrolled proliferation, apoptosis resistance, and increased invasiveness. In this study, we performed the comprehensive proteomic and small RNA analysis of EVs isolated from a T. annulata Kashi isolate-infected bovine lymphocyte cell line (TaXJS), B cell line (TaBC), dendritic cell line (TaDC), and from the sera of cattle before and after infection. Our label-free LC-MS/MS proteomics identified 2580 proteins, while small RNA sequencing revealed 6635 miRNAs associated with parasite development, host invasion, and immune evasion. Functional enrichment analyses recognized vesicular components involved in key pathways of the parasite-host such as ECM-receptor interaction, oxidative phosphorylation, and proton transport. These findings highlight the potential of Theileria-derived EVs in modulating host responses and their potential as therapeutic and vaccine targets.
