Gene expression profiling of the response to interferon beta in EBV-transformed and primary B cells of patients with multiple sclerosis

ABSTRACT: To identify gene expression changes and pathways induced by interferon-? (IFN-?) in B cells, we studied the in vitro response of EBV-transformed B cells (lymphoblast cell lines-LCLs). LCLs were derived from an MS patient repository. Whole genome expression analysis identified 115 genes that were more than two-fold differentially up-regulated following IFN-? exposure, with over 50 novel IFN-? response genes. Pathways analysis demonstrated that IFN-? affected LCLs in a similar manner to other cell types by activating known IFN-? canonical pathways. Additionally, IFN-? increased the expression of innate immune response genes, while down-regulating many B cell receptor pathway genes and genes involved in adaptive immune responses. Several of the novel response genes were tested and validated
