Modulation of Haemophilus-induced cytokine production in dendritic cells by Prevotella species.
IL-23, IL-12p70 and IL-10 cytokine production measured in DC culture supernatants 24 h following stimulation with non-typeable Haemophilus influenzae (H. inf. NT) in combination with Prevotella melaninogenica (P. mel.), Prevotella nanceiensis (P. nan.) or Prevotella salivae (P. sal.). The effect of Prevotella species on Haemophilus-induced cytokine production was calculated relative to Haemophilus stimulation alone for each donor. The numbers identify individual donors (n = 3–5). *p<0.05, **p<0.01.
