Toll-like receptor 3 (TLR3) also known as CD283 (cluster of differentiation 283) is a protein that in humans is encoded by the TLR3 gene. TLR3 is a member of the toll-like receptor family of pattern recognition receptors of the innate immune system. TLR3 recognizes double-stranded RNA in endosomes, which is a common feature of viral genomes internalised by macrophages and dendritic cells. WebThe mutation occurred on different TLR3 haplotypes in the children. Stimulation of heterozygous dermal fibroblasts or monocyte-derived dendritic cells with poly (I:C), but not lipopolysaccharide, showed hyporesponsiveness in patient cell lines that could be reversed by transfection of wildtype TLR3.
WebAll TLRs except TLR3 use a signaling protein called MyD88 (myeloid differentiation primary response protein 88), a protein that allows the innate immune cell to function normally. MyD88 deficiency was initially described in nine children suffering from recurrent and severe pus-forming or pyogenic bacterial infections.
