Scientific Background:The initial recognition of pathogens during host defense is mediated by a family of receptors termed toll-like receptors (TLR). TLRs recognize conserved microbial components, termed pathogen-associated molecular patterns (PAMPs). To date, 11 TLRs have been cloned in mammals and each receptor appears to be involved in the recognition of a unique set of PAMPs that are distinct in their chemical nature and structure. TLR11 has a role in uropathogenic E. coli infection and senses the profilin protein from the protozoan parasite Toxoplasma gondii. Profilins are a class of small actin-binding proteins present only in eukaryotic cells. T. gondii profilin shares significant homology only with profilin genes from other apicomplexan protozoa, such as the malaria parasite, Plasmodium falciparum, suggesting that TLR11 may be involved in the recognition of these parasites. Profilin activates and induces TLR11-dependent IL-12p40 production from dendritic cells, and is known to bind TLR11 from mouse.
