Description
Acquisition of effector properties is a key step in the generation of cytotoxic T lymphocytes (CTLs). Here we show that inflammatory signals regulate Dicer expression in CTL, and that deletion or depletion of Dicer in mouse or human activated CD8+ T cells causes upregulation of perforin, granzyme and effector cytokines. Genome-wide analysis of miRNA changes induced by exposure of differentiating CTLs to IL-2 and inflammatory signals identifies miR-139 and miR-150 as components of a miRNA network that controls perforin, eomesodermin (Eomes) and IL-2Ra expression in differentiating CTLs and whose activity is modulated by IL-2, inflammation and antigenic stimulation. Overall our data show that strong IL-2R and inflammatory signals act through Dicer and miRNAs to control the cytolytic program and other aspects of effector CTL differentiation. Overall design: Comparison of control and Dicer knock-out CTLs differentiated in vitro; Comparison of wild type CTLs differentiated in vitro with or without inflammatory stimuli; Comparison of effector and memory precursor CTLs isolated from mice infected with LCMV-Armstrong

Description
Purpose: identify genes regulated by expression of miR-31 in primary mouse CD8 T-cells by exogenously expressing pre-miR-31 from the Plko.3g lentiviral vector. Cells infected with empty Plko.3g vectors were used as controls for infection.

Description
STAT3 is an immidiate regulator of Th17 differentiation. STAT3 difieciency downmodulate Th17 specific genes and Th17 responses. Therefore, we intend to identify genome wide targets of STAT3.
