Influence of Micro- and Nanoplastics on Mitochondrial Function in the Cardiovascular System: A Review of the Current Literature
Summary
This review examined the limited but growing research on how micro- and nanoplastics may affect mitochondrial function in the cardiovascular system. Researchers noted that these plastic particles can trigger oxidative stress and disrupt normal mitochondrial processes, which are critical for heart and blood vessel health. The study highlights the need for more comprehensive research given the rising levels of plastic particle contamination and the importance of mitochondrial health in preventing cardiovascular problems.
Mitochondria represent pivotal cellular organelles endowed with multifaceted functionalities encompassing cellular respiration, metabolic processes, calcium turnover, and the regulation of apoptosis, primarily through the generation of reactive oxygen species (ROS). Perturbations in mitochondrial dynamics have been intricately linked to the etiology of numerous cardiovascular pathologies, such as heart failure, ischemic heart disease, and various cardiomyopathies. Notably, recent attention has been directed towards the detrimental impact of micro- and nanoplastic pollution on mitochondrial integrity, an area underscored by a paucity of comprehensive investigations. Given the escalating prevalence of plastic particle contamination and the concomitant burden of cardiovascular disease in aging populations, understanding the interplay between mitochondria within the cardiovascular system and micro- and nanoplastic pollution assumes paramount importance. This review endeavors to elucidate the current albeit limited comprehension surrounding this complex interplay. Key words Mitochondria, Nanoplastics, Microplastics, Cardiovascular system, Endothelial function, Oxidative phosphorylation.
