Description
Celiac disease is an autoimmune inflammatory condition triggered by an immune-mediated response to dietary gluten. Celiac disease has traditionally been explained by the interaction between genetic susceptibility and gluten exposure. However, this model does not fully explain variability in disease onset. It is important to investigate whether gastrointestinal microbial dysbiosis promoting zonulin-mediated intestinal permeability increases immune activation in genetically predisposed individuals, contributing to celiac disease development. Current literature demonstrates that patients with celiac disease frequently exhibit altered gut microbiota composition leading to gut microbial dysbiosis, with overgrowth of harmful bacteria and decreased beneficial bacteria. This disruption in microbe diversity changes zonulin levels in the gut. Elevated zonulin compromises epithelial tight junction integrity, thus increasing intestinal permeability. Increased intestinal permeability may permit greater translocation of immunogenic gluten peptides across the intestinal barrier, amplifying autoimmune responses. This research will utilize a structured literature review of peer-reviewed publications, examining associations between microbiome alterations, zonulin expression, gut barrier dysfunction, and celiac disease pathogenesis. A revised model of celiac disease pathogenesis points to treatment strategies aimed at altering gut microbiota or directly regulating zonulin levels. Further research could investigate the clinical effectiveness of such changes in genetically at-risk populations at either decreasing the incidence or increasing onset time of celiac disease development, offering preventative interventions for a currently incurable chronic illness.
