Toll-like receptor (TLR) agonists represent potentially useful cancer vaccine adjuvants in
their ability to stimulate antigen-presenting cells (APCs) and subsequently amplify the
cytotoxic T-cell response. The purpose of this study was to characterize APC responses to
TLR activation and to determine the subsequent effect on lymphocyte activation. We
exposed murine primary bone marrow-derived macrophages to increasing concentrations of
agonists to TLRs 2, 3, 4, and 9. This resulted in a dose-dependent increase in production of …

Methods IL-10 siRNA constructs were designed and tested for their ability to suppress IL-10
secretion from a macrophage cell line by quantitative real-time polymerase chain reaction.
Murine primary bone marrow derived macrophages were harvested, lipofected with IL-10
siRNA, and stimulated with CpG oligonucleotide, a TLR-9 agonist. Macrophage tumor
necrosis factor-alpha (TNF-alpha) and IL-10 secretions were measured. Autologous murine
splenocytes were then exposed to both supernatants from the stimulated macrophages and …
