Toll Like Receptors as Sensors of the Tumor Microbial Dysbiosis: Implications in Cancer Progression

Microbiota is a complex ecosystem of active microorganisms resident in the body of mammals. Although the majority of these microorganisms resides at the distal gastrointestinal tract, high-throughput DNA sequencing technology have made possible to understand that several other tissues of the human body host their own microbiota, even those once considered sterile, such as lung tissue. These bacterial communities have important functions in maintaining a healthy body state and the host immune system has evolved multiple mechanisms by which maintaining a symbiotic relationship with the microbiota. The maintenance of this dialogue allows the induction of protective responses to pathogens and r…
