Author comment: Mitochondria as a target of micro- and nanoplastic toxicity — R0/PR1
This review examines how microplastics and nanoplastics disrupt the function of mitochondria — the cell's energy-producing organelles — by triggering oxidative stress, altering membrane potential, and interfering with cell signaling. Because mitochondrial dysfunction is linked to neurodegenerative disease, cancer, diabetes, and cardiovascular conditions, this work raises concern that microplastic exposure could contribute to or worsen these diseases. The authors call for more targeted research into how plastic particles interact with cellular energy systems.
Author comment: Mitochondria as a target of micro- and nanoplastic toxicity — R1/PR4
This review details how micro- and nanoplastics disrupt mitochondria — the energy-producing structures inside cells — by generating reactive oxygen species, altering membrane potential, and interfering with the quality-control processes cells use to maintain healthy mitochondria. Because mitochondrial dysfunction is a common driver of neurodegenerative diseases, cancer, diabetes, and cardiovascular disease, these findings suggest a plausible cellular mechanism linking plastic particle exposure to serious chronic illness. The review calls for more research into mitochondria as a key target of plastic toxicity.
