特徴

• TLR11 is a type I transmembrane receptor of the Toll­like receptor family that is primarily expressed in epithelial cells in the liver, kidney, bladder and intestines, as well as in dendritic cells and macrophages (1­3). The 926 amino acid (aa) mouse TLR11 transcript encodes a 30 aa signal sequence, a 691 aa extracellular domain (ECD) with 10 leucine­rich repeats and 9 potential N­glycosylation sites, a 21aa transmembrane domain, and a 184aa cytoplasmic domain with a TIR domain (1). Within the ECD, mouse and rat TLR11 share 86% aa sequence identity. Human TLR11 is a pseudogene that is not expressed. Some researchers have found TLR11 in the dendritic cell plasma membrane, where it cooperates with MyD88 to take up antigen and initiate cell signaling (3­5). Others have found it in the endoplasmic reticulum (ER), where it interacts with the multispan ER protein UNC93B1 (6). TLR11 recognizes profilin proteins on Toxoplasma gondii and other intracellular parasites (3, 7). Binding of profiln activates dendritic cell subsets to expand, mature, produce IL­12, and present antigenic profilin peptides to T cells (2­4). TLR11 is also reported to recognize pathogenic bacteria in the urinary tract (1). In the intestines, it is expressed on M cells, where its recognition of pathogenic salmonella blocks their entry into Peyer’s patches (8). TLR11 allows mice to be resistant to Salmonella typhi, the organism causing typhoid fever, while humans are sensitive (9).
