CD8(+) T-cell functions are critical for preventing chronic viral infections by eliminating infected cells. For healthy immune responses, beneficial destruction of infected cells must be balanced against immunopathology resulting from collateral damage to tissues. These processes are regulated by factors controlling CD8(+) T-cell function, which are still(More)
Treatment of primary or immortalized human airway epithelial cells (16HBE14o-, S9) or alveolar cancer cells (A549) with recombinant hemolysin A (rHla), a major virulence-associated factor of Staphylococcus aureus, induces alterations in cell shape and formation of paracellular gaps in the cell layer. Semiquantitative Western blotting using extracts of(More)
Type I IFNs are critical in initiating protective antiviral immune responses, and plasmacytoid dendritic cells (pDCs) represent a major source of these cytokines. We show that only few pDCs are capable of producing IFN-β after virus infection or CpG stimulation. Using IFNβ/YFP reporter mice, we identify these IFN-β-producing cells in the spleen as a(More)
