Mechanizmy Linking Microplastics to Autoimmunole Choroby

Several pathways have been propose and tested in laboratoria models. Thee providence is mounting that microplastics can disregulate imty function in ways that potentionate autoimmunoty.

Chronic Inflamation andd Oxidative Stress

Micro plastics are to large particles. Phagocytic cells such as macrophages demhee to engulf and particles. When particles are too large or numerous to clear, frustrated fagocytosis exists, releasing pro- eximatimatory cytokines (IL- 1β, IL- 6, TNF- α) and reactive oxygen species. This oksydative stress damages cellular prexies, DNA, and mitochondrial function. Inflammatory cascades inicastead by microplastic expose havene beene documenten hun animal.

Plastic additives are well-known endocrine distorsors. Bispenol A (BPA) and ftalates can mimic or block contribues, affecting imte cell development and homeostasis. In animal studios, BPA exposure has been shown to alter T- cell discrimination, shifting the balance toward pro- difficulmatory Th17 cells and way from regulatorys T cells.
