Background: TLR8

Toll-like receptor 8 (TLR8) is a member of the TLR family of receptors that play a role in innate immune system activation and the recognition of pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs) (1,2). TLRs are type I membrane receptors that can be expressed on either the cell surface or internally, on endosomes (1,2). TLR8 is an endosomal receptor and is activated by pathogenic single stranded (ss) RNA (1-3). TLR8 is located on the X chromosome and is expressed mostly in monocytes/macrophages, neutrophils, and myeloid dendritic cells (1-3). Structurally, TLR8 consists of an extracellular domain, a cysteine-rich region, and transmembrane domain, and a Toll/Interleukin-1 receptor homology (TIR) domain (3,4). The extracellular domain contains a N-terminal leucine rich repeat (LRRNT) and a C-terminal LRR (LRRCT) which have 26 LRRs between them, each approximately 20-30 amino acids (aa), and a Z-loop between LRR14 and LRR15 (3). The primary isoform of the human TLR8 is synthesized as a protein 1041 aa in length with a theoretical molecular weight of ~120 kDa (4).

TLR8 is highly similar to TLR7 and both pathways are mediated by the adapter protein MyD88 to signal through IFN regulatory factor 7 (IRF7) and nuclear factor (NF)-kappaB (1-3,5). However, TLR7 recognizes guanosine and GU-rich ssRNA, while TLR8 recognizes uridine and AU-rich sequences (2,5). TLR7/TLR8 agonists, including derivatives of the immunostimulatory imiquimod, have been shown to be a promising cancer therapy capable of providing anticancer signals to antigen presenting cells (APCs), with many agonists being tested in both pre-clinical and clinical trials (6). Similarly, studies suggest that agonists for TLR8, in combination with other individual TLR agonists and antagonists, may also be useful for treating inflammatory allergic diseases, such as allergic rhinitis (7).
