Multiple Signaling Molecules are Involved in Expression of CCL2 and IL-1β in Response to FSL-1, a Toll-Like Receptor 6 Agonist, in Macrophages.

TLR6 forms a heterodimer with TLR2 and TLR4. While proinflammatory roles of TLR2 and TLR4 are well documented, the role of TLR6 in inflammation is poorly understood. In order to understand mechanisms of action of TLR6 in inflammatory responses, we investigated the effects of FSL-1, the TLR6 ligand, on expression of chemokine CCL2 and cytokine IL-1β and determined cellular factors involved in FSL-1-mediated expression of CCL2 and IL-1β in mononuclear cells.
