WebFurther detailed studies suggested that hypersensitive Tlr7 signaling enables the survival of B cells that bind to self-antigen through their surface BCR, and that the autoimmunity is independent of germinal centers. Deficiency of Myd88, a protein downstream of Tlr7, rescued the phenotype and normalized the cellular and serologic phenotype. WebThe increased TLR7 signalling has been implicated in the development of SLE and other autoimmune conditions by various mouse models and the GWAS studies of the patients with autoimmune diseases. This study is the first description of the missense gain-of-function TLR7 variant as the causal factor for SLE in humans and mice. This study provides ...

Lupus Linked to TLR7 Mutations, Related Signaling Changes

WebToll-like receptors (TLRs), such as TLR7, are a critical part of the evolutionarily conserved innate immune system. TLRs have specificity for different bacterial components, such as lipopolysaccharide (TLR4; 603030 ), bacterial lipoproteins (TLR2; 603028 ), and unmethylated CpG dinucleotides (TLR9; 605474) (summary by Kadowaki et al., 2001 ). WebJun 9, 2024 · TLR7 is an intracellular receptor mainly expressed in B cells and plasmacytoid dendritic cells (pDCs) that recognizes pathogen-associated molecular patterns [ 44 ]. Overexpression of TLR7 results in more severe autoimmune responses and greater incidence of lupus-like disease [ 45, 46 ].
