TLR3 is activated during viral infection. To view automatically seeded indices concerning Toll-like Receptors, see:Ī variant of TLR3 confers protection agains geographical atrophy. Īrticles in Proteopedia concerning Toll-like Receptors include: TLR13 is activated by a motif in bacterial ribosome 23S RNA and is not present in human.TLR9 is involved in the activation of innate immunity.TLR8 is linked to the control of CD4+ regulatory T cells.TLR7 stimulation promotes autoimmune diabetes in mice.TLR6 is involved in the discrimination of bacterial lipoproteins by the immune system.TLR5 protects mice against Clostridium induced colitis.TLR4 is the central lipid recognition protein in the lipopolysaccharide receptor complex.TLR2 is likely involved in specific B cell-mediated functions.The extracellular domains contain leucine-rich repeats. The receptors are multi-domain structures consisting of an extracellular ectodomain, a transmembrane domain and a intracellular Toll/IL-1 receptor domain. ![]() The Toll-like receptors recognize molecular patterns associated with pathogens, such as double-stranded RNA, lipopolysaccharide, or CpG DNA, and initiate an intracellular kinase cascade, inducing an immediate defensive response. There are 6 types of enzyme-linked receptors.Toll-like receptors, often abbreviated TLRs, are found on the surface of phagocytic cells of vertebrates and invertebrates and are critical to the innate immune system. Irregularities in signaling via enzyme-linked receptors play a key role in disorders related to cell growth, proliferation, migration, survival, and differentiation, all of which are associated with the development of cancer. ![]() They also have an intracellular domain whose catalytic action is regulated by the binding of an extracellular ligand. These types of receptors have an extracellular binding site for chemical signaling. They are also known as catalytic receptors.
