THE JOINT-GUT AXIS: SYSTEMIC TRANSLOCATION OF INGESTED PLASTICS TO JOINT SPACES

Abstract The spread occurrence of micro and nanoplastics in food and potable water raises serious concerns about their health effects. The growing evidence points to the gastrointestinal tract being the main entry point for these small particles that initiate a cascade of reactions that go far beyond mild gastrointestical discomfort and ingestion, microplastics trigger oxidative stress responses, disrupt epithelial integrity, impair barrier function, and dysregulate the gut microbiota host dialogue. The gut microbiota is followed by increased intestinal permeability and entry of plastic particles into systemic circulation, either through the hepatic portal vein or lymphatic system, and activation of gut-associated lymphoid tissue. The activation of the inflammasome and increases the quantity of pro-inflammatory cytokines in the inflamed intestine. Monocytes, macrophages, and dendritic cells enter the blood circulation and invade the inflamed, fibrotic, and eroded joints, then the synovial cells, macrophages, osteoblasts, and chondrocytes ingest plastic material. In the joint, the presence of foreign material causes oxidative stress, activation of the inflammasome, and activation of metalloproteinases that lead to the destruction of cartilage, dysfunction of chondrocytes, and pathological remodeling of bone. In microplastics appear to be involved in a process that starts in the gastrointestinal tract and contributes to persistent inflammation of the joints. The mechanisms by which diet-derived plastics influence the gut microbiota-host immune interactions is critical for furthering the understanding of how microplastics affect the etiology and pathogenesis of joint diseases.
