ABSTRACT
Periodontal disease can be initiated by a shift from a symbiotic to a dysbiotic microbial community. An increase in the recruitment of leukocytes and production of inflammatory cytokines, chemokines and oxidative stress are generated by this shift. In periodontitis, an exacerbated, poorly specific and effective inflammatory response is mounted. Moreover, failure in the inflammation resolving mechanism leads to establishment of a chronic inflammatory process, resulting in the progressive destruction of bone and soft tissue. In different diseases presenting chronic inflammation some important players of immune response are defectives. Thus, an immunosuppressive environment could be induced during chronic inflammation. Myeloid derived suppressor cells (MDSC), a heterogenic group of immature myeloid cells with potent immune suppressive activity, are increased in several acute and chronic inflammatory diseases. Dysbiosis-mediated inflammation can induce increased frequency of MDSC. In addition, mediators generated in diverse inflammatory diseases have demonstrated to promote expansion, activation and recruitment of MDSC, similar mediators have been described in periodontal disease. MDSC promote generation of nitric oxide (NO) and reactive oxygen species (ROS). Furthermore, MDSC can differentiate in functional osteoclasts. We hypothesize that MDSC are generated during periodontal disease. Review of literature evaluating this hypothesis and possible implications are assed in this work. It encourages the study of MDSC in this common disease.
