Figure 6. The results of ELISA showed the release of IL-6 and IL-8 from HCFs only pretreated with anti-TLR2 and anti-TLR4 monoclonal antibodies. Data are the mean±SEM of triplicates from an experiment that was repeated three times with similar results. The results show that incubation with anti-TLR2 and/or anti-TLR4 mAb had little effect on the production of IL-6 and IL-8.
