Acetic acid alone inhibits TLR-elicited IL-6, IP-10, and RANTES production from lower female reproductive tract epithelial cells. Ect (left panels), VK2 (center panels), and primary cervicovaginal epithelial cells (right panels) seeded into plates were treated with 100 mM acetic acid (Acetic) at pH 7 for 24 h in the absence or presence of stimulation with the TLR agonist PIC. Production of IL-6 (A–C), IP-10 (D–F), and RANTES (G–I) was quantified from supernatants. Graphs show mean and standard error of the mean from n = 4 independent assays. P ≤ 0.05 are denoted as * (as determined by Mann-Whitney test). + denotes a significant difference (p < 0.05) as compared to untreated (UT) cells. PIC, polyinosinic:polycytidylic acid.
