From: The oral microbiome in autoimmune diseases: friend or foe?
The bidirectional role of oral microbiota in the organism: eubiosis and dysbiosis. The eubiosis of oral microbiota contribute to homeostasis maintaining. Within microbiota dysbiosis, the homeostasis between the host and commensal is destroyed, accompany by abnormal immune response and leading to IBD, RA, SLE, SS, AS, MS, AILDs, IgAN. IBD, Inflammatory bowel disease;Â RA, Rheumatoid arthritis; SLE, Systemic lupus erythematosus; SS, Sjogren syndrome; AS, Ankylosing spondylitis; MS, Multiple sclerosis; AILDs, Autoimmune liver diseases; IgAN, Immunoglobulin A nephropathy
