Mammals are colonized with an indigenous microbiota consisting of trillions of microorganisms. These microorganisms provide numerous benefits to host biology. Toll-like receptors (TLR) are an evolutionarily conserved family of receptors which recognize invariant structures, known as pathogen associated molecular patterns (PAMPs), present on microorganisms. TLR are critical in orchestrating both the inflammatory and adaptive arms of the immune response in protection from infection with microbial pathogens. However these effector immune responses can be deleterious to the host if unregulated. TLR cannot a priori distinguish between PAMPs derived from pathogenic or non-pathogenic microorganisms.

520 $a Mammals are colonized with an indigenous microbiota consisting of trillions of microorganisms. These microorganisms provide numerous benefits to host biology. Toll-like receptors (TLR) are an evolutionarily conserved family of receptors which recognize invariant structures, known as pathogen associated molecular patterns (PAMPs), present on microorganisms. TLR are critical in orchestrating both the inflammatory and adaptive arms of the immune response in protection from infection with microbial pathogens. However these effector immune responses can be deleterious to the host if unregulated. TLR cannot a priori distinguish between PAMPs derived from pathogenic or non-pathogenic microorganisms.
520 $a The goal of this dissertation has been to determine how deleterious responses to the indigenous microbiota are avoided and to understand the role of TLRs in the recognition of the commensal microflora.
520 $a The experiments described herein reveal an unexpected beneficial role of commensal-TLR interactions in intestinal homeostasis and protection from injury. Relatedly, TLRs also appear to be important positive regulators of intestinal tumorigenesis. The study of two models of commensal-dependent, spontaneous colitis has revealed that immune intestinal homeostasis is maintained by non-redundant regulation of recognition of the indigenous microbiota involving both TLR-dependent and TLR-independent pathways.
