TLR11 Activation of Dendritic Cells by a Protozoan Profilin-Like Protein
Felix Yarovinsky,1*Dekai Zhang,3John F. Andersen,2Gerard L. Bannenberg,4Charles N. Serhan,4Matthew S. Hayden,3Sara Hieny,1Fayyaz S. Sutterwala,3Richard A. Flavell,3Sankar Ghosh,3Alan Sher1*
Mammalian Toll-like receptors (TLRs) play an important rolein the innate recognition of pathogens by dendritic cells (DCs).Although TLRs are clearly involved in the detection of bacteriaand viruses, relatively little is known about their functionin the innate response to eukaryotic microorganisms. Here weidentify a profilin-like molecule from the protozoan parasiteToxoplasma gondii that generates a potent interleukin-12 (IL-12)response in murine DCs that is dependent on myeloid differentiationfactor 88. T. gondii profilin activates DCs through TLR11 andis the first chemically defined ligand for this TLR. Moreover,TLR11 is required in vivo for parasite-induced IL-12 productionand optimal resistance to infection, thereby establishing arole for the receptor in host recognition of protozoan pathogens.
