In the past decade, microplastics (MPs) have drawn significant attention as widespread environmental contaminants, with research increasingly highlighting their harmful effects on respiratory health in aquatic and terrestrial organisms. Findings revealed human lung tissues, raising concerns about potential role damaging tissue integrity contributing to pulmonary fibrosis-a chronic inflammatory condition characterized by scarring of epithelial tissues due accumulated extracellular matrix, triggered factors such alcohol, pathogens, genetic mutations, pollutants. this review, we explore both well-studied lesser-studied mechanisms signaling pathways, aiming shed light how might act mediators that activate distinct, often overlooked cascades. This review searched PubMed Google Scholar using keywords like "plastic," "microplastic," "lung fibrosis," "pulmonary system," "exposure route," "signaling pathways," combined "OR" "AND" singular plural forms. These pathways could not only induce damage but also play a development fibrosis. be targeted reduce microplastic-induced fibrosis, opening new avenues for future treatments.
