Recognition of nucleic acids is a key strategy of the innate immune system to detect infectious organisms and tissue damage. Toll-like receptor (TLR) 8 was long assumed to be a receptor for single-stranded (ss) RNA. Unexpected findings now suggest that TLR8 recognizes RNA degradation products rather than ssRNA and that synergistic binding of two uridine-containing agonists at distinct sites of the receptor leads to activation of the innate immune response.
