HRS cells in HL secrete factors that interact with the inflammatory background cells and may serve as biomarkers for disease activity. To detect new proteins related to pathogenesis, we analyzed the secretome of HRS cells. Proteins in cell culture supernatant of four HL cell lines were identified using 1DGE followed by in-gel trypsin digestion and LC-MS/MS. In total 1290 proteins, including 368 secreted proteins, were identified. Functional grouping of the secreted proteins revealed a total of 37 proteins involved in immune response. 16 of the 37 proteins, i.e. ALCAM, Cathepsin C, Cathepsin S, CD100, CD150, CD26, CD44, CD63, CD71, Fractalkine, IL1R2, IL25, IP-10, MIF, RANTES and TARC were validated in HL cell lines and patient material using immunohistochemistry and/or ELISA. Expression of all 16 proteins was confirmed in HL cell lines and 15 of these were also confirmed in HL tissues. Seven proteins (ALCAM, Cathepsin S, CD26, CD44, IL1R2, MIF and TARC) revealed significantly elevated levels in patient plasma compared to healthy controls. Proteomics analyses of HL cell line supernatant allowed the detection of new secreted proteins, which may add to our insights in the interaction between HRS cells and infiltrating lymphocytes and in some instances might serve as biomarkers.
