However, the importance of innate immunity has been noted only recently. Based on the proposed role of microorganisms in the pathogenesis of the disease, we hypothesize that patients with PBC possess a hyper-responsive innate immune system to pathogen-associated stimuli that may facilitate the loss of tolerance. To address this issue, we isolated peripheral blood monocytes from 33 patients with PBC and 26 age-matched healthy controls and stimulated such cells<\/jats:bold>\n                                 <jats:bold>\n                                    in vitro\n                                 <\/jats:bold>\n                                 <jats:bold>with defined ligands for toll-like receptor (TLR) 2 (lipoteichoic acid; LTA), TLR3 (polyIC), TLR4 (lipopolysaccharide; LPS), TLR5 (flagellin), and TLR9 (CpG-B). Supernatant fluids from the cultures were analyzed for levels of 5 different pro-inflammatory cytokines, interleukin (IL)-1\u03b2, IL-6, IL-8, IL-12p70, and TNF-\u03b1.
