Brief description Genes down-regulated in activated CD8 T cells: wildtype versus MIR155 [GeneID=406947] knockout.
Full description or abstract MicroRNA-155 (miR-155) is upregulated in primary effector CD8 T cells but is expressed at low amounts in na´ve cells. Anti-viral CD8 T cell responses and viral clearance were impaired in miR-155 deficient (bic-/-) mice, and this defect was intrinsic to CD8 T cells, as adoptively transferred bic-/- CD8 T cells generated greatly reduced primary and memory responses during infection. To understand the mechanism by which miR-155 regulates CD8 T cell activation, we analyzed the gene expression profiles of naive and in vitro activated wild-type and bic-/- CD8 T cells.
