Figure 2. Chlamydia-induced trophoblast pro-IL-1β expression and secretion of IL-1β and IL-8 is independent of TLR2 and TLR4.

Figure 2

Wildtype trophoblast (3A and HTR8) and trophoblast cells transfected to express either a TLR2-dominant negative (DN) (in 3A cells) or a TLR4-DN (in HTR8 cells) were either NI or infected with Ct for 48hrs. (a & b) Cell lysates were evaluated for pro-IL-1β expression by Western blot (representative blots are shown). Barcharts show quantification of pro-IL-1β levels, as determined by densitometry and normalized to β-actin. Culture supernatants were analyzed for (c & d) IL-1β and (e & f) IL-8 levels by ELISA. Data are pooled from three independent experiments and no significance was observed between the response of wildtype and TLR2-DN or TLR4-DN cells to Ct infection.
