The presence of the capsular polysaccharide (CPS) interferes with Streptococcus suis-induced interferon (IFN)-β expression by dendritic cells (DCs), while the suilysin (SLY) is partially responsible for its activation. Role of the CPS, SLY, and cell wall modifications (D-alanylation of the lipoteichoic acid, Δdlta, or N-deacetylation of the peptidoglycan, ΔpgdA) in IFN-β mRNA expression by DCs 6 h following infection with the wild-type or mutant S. suis strains. Data represent the mean ± SEM (n = 4). a (p < 0.001) indicates a significant difference between P1/7 and P1/7ΔcpsF; b (p < 0.01) between 31533 and 31533Δsly.
