Porcine circovirus type 2 (PCV2)-mediated inhibition of natural interferon producing cell (NIPC) cytokine induction. Enriched NIPCs (Percoll/CD4 protocol) received PCV2 at 3 50% tissue culture infectivity doses (TCID50)/cell 1 hr before addition of cytosine-phosphorothioate-guanine (CpG) (10 µg/ml), R837 (10 µg/ml), pseudorabies virus (PRV) (TCID50/cell), classical swine fever virus (CSFV) (0·1 TCID50/cell) or transmissible gastroenteritis virus (TGEV) (0·1 TCID50/cell). Supernatants were harvested from the cultures after 24 hr and tested for(a)interferon (IFN)-α,(b)interleukin (IL)-12,(c)tumour necrosis factor (TNF)-α and(d)IL-6. The results represent three independent experiments.
