Innate immunity is the body’s first line of defense against invading microbes. This component of our immune system relies on highly conserved pattern-recognition receptors (PRRs) to distinguish different pathogens.1 Toll-like receptors (TLRs) are one class of PRR1,2 of which ten (TLR1-10) have now been identified in mammals.1-3 TLRs recognize pathogen-associated molecular patterns (PAMPs) and initiate the appropriate immune responses. These entail the activation of signal cascades leading to the secretion of cytokines, the activation of cell-surface molecules and the production of pathogen-specific immunoglobulins (Ig).4 As TLRs are constitutively expressed on immune cells and are responsive to synthetic ligands, they provide us with a rational way with which to modulate the immune system; a strategy which can be seen as quite distinct from conventional vaccination.
