Thus, this study investigated the effects of lipopolysaccharides from Porphyromonas gingivalis (PgLPS) on cell metabolic activity, expression of pro-inflammatory cytokines and stem cell markers, and osteoblast/cementoblast differentiation potential of periodontal ligament stem cells (PDLSCs).
Examples are: (i) the demonstration that lipid A, the glycolipid moiety from lipopolysaccharides, is the critical unit for the immunobiological activity of LPS [12], (ii) the successful chemical synthesis of lipid A [13-16], (iii) the first total synthesis of the naturally occurring Re-type LPS [17,18], and (iv) the discovery of Toll-like receptor-4 (TLR-4) as a key cellular receptor molecule for LPS [19-21].
