Endogenous TLR ligands and autoimmunity.
نویسنده
چکیده
Based on an evolutionary conserved repertoire Toll-like-receptors (TLRs) donate specificity to innate immune cells. Therefore, TLRs are considered as paradigmatic for "self" versus "non-self" discrimination. This view, however, needs to be modified since TLR's also appear to recognise "endogeneous", that is host-derived ligands, examples being host-derived DNA and -RNA. Here I discuss physiological and pathophysiological consequences of endogeneous ligand-recognition by TLRs. I conclude that endogeneous ligand recognition by TLRs drives sterile inflammation sustained by innate immune cells in certain autoimmune disorders.

Role of Toll like receptor-activated dendritic cells in the development of autoimmunity.
The recognition of microbial stimuli by Toll-like receptors (TLRs) expressed on dendritic cells (DCs) is essential for the regulation of immune responses. DC activation via TLRs leads to the production of proinflammatory cytokines, chemokines and surface molecules that play a key role in the regulation and control of inflammatory reactions and adaptive immunity. Minor imbalances in the feedback...
متن کاملRegulatory roles for NKT cell ligands in environmentally induced autoimmunity.
The development of autoimmune diseases is frequently linked to exposure to environmental factors such as chemicals, drugs, or infections. In the experimental model of metal-induced autoimmunity, administration of subtoxic doses of mercury (a common environmental pollutant) to genetically susceptible mice induces an autoimmune syndrome with rapid anti-nucleolar Ab production and immune system ac...
متن کاملCutting Edge: DNase II deficiency prevents activation of autoreactive B cells by double-stranded DNA endogenous ligands.
In mice that fail to express the phagolysosomal endonuclease DNase II and the type I IFN receptor, excessive accrual of undegraded DNA results in a STING-dependent, TLR-independent inflammatory arthritis. These double-knockout (DKO) mice develop additional indications of systemic autoimmunity, including anti-nuclear autoantibodies and splenomegaly, that are not found in Unc93b1(3d/3d) DKO mice ...
متن کاملMicrobial products trigger autoimmune ocular inflammation.
PURPOSE Microbial products stimulate the immune system by interacting with Toll-like receptors (TLR) on antigen-presenting cells. This study examined the hypothesis that microbial products, which function as TLR ligands, are playing a major role in triggering pathogenic autoimmunity. METHODS An experimental system was developed in which microbial TLR ligands were tested in vivo for their capa...
متن کاملEndogenous toll-like receptor ligands and their biological significance
Toll-like receptors (TLRs), a family of pattern recognition receptors, recognize and respond to conserved components of microbes and play a crucial role in both innate and adaptive immunity. In addition to binding exogenous ligands derived from pathogens, TLRs interact with endogenous molecules released from damaged tissues or dead cells and regulate many sterile inflammation processes. Putativ...
