Anti-TLR2 inhibits mycoplasma LPP but not MMF induction of IL-8. BEAS-2B cells were pretreated with an anti-TLR2 antibody overnight prior to incubation with either 1 μg/ml Pam3Cys lipopeptide (A), 10 μg/ml M. pneumoniae lipoprotein (LPP) (B), or 10 μg/ml MMF (C), for an additional 48 h, followed by assay for IL-8 by electrochemiluminescence. **P < 0.01 ***P < 0.001 compared with their respective bar 2. Data shown are the means (SD) for three independent experiments. D: BEAS-2B cells pretreated with 50 μg/ml of nonimmune goat IgG antibody, followed by stimulation with LPP, and assay for IL-8. Data shown are representative of two independent experiments.
