Toll-like receptors (TLRs) are type I transmembrane signaling receptors characterized by containing leucine-rich repeats (LRR) extracellular domain and IL-1 receptor like intracellular domain. TLRs are responsible for recognizing pathogen-associated molecule patterns (PAMPs). They are primary sensors of both innate and adaptive immune systems. To date a total of 12 TLRs have been identified. Toll-like receptor 6 (TLR6), known as CD286, is one of the important receptors. TLR6 is colocalized with TLR2 on the cell surface of monocytes/macrophages, dendritic cells, granulocytes. The TLR2/TLR6 complex plays a role in the innate immune response to diacylated lipoprotein and peptidoglycan antigens.
