Micro/nanoplastic-driven cardiovascular senescence and multi-target intervention by traditional Chinese medicine
Summary
Researchers reviewed how micro- and nanoplastics accumulate in cardiovascular tissues and accelerate cellular aging through mitochondrial damage, epigenetic changes, telomere shortening, and chronic inflammation, while also highlighting traditional Chinese medicine's multi-target compounds as a potential countermeasure by simultaneously addressing oxidative stress, fibrosis, and cell death pathways.
Micro/nanoplastics (MNPs), pervasive environmental pollutants, accumulate in cardiovascular tissues and drive premature aging through multiscale pathophysiological cascades. This review synthesizes evidence establishing environmental phenotypic aging as a novel mechanistic link between MNP exposure and cardiovascular senescence. MNPs induce mitochondrial damage involving cristae disruption and mtDNA leakage activating cGAS-STING, epigenetic reprogramming encompassing METTL3-mediated m6A hypermethylation and SIRT1/3 suppression, telomere attrition, and NLRP3 inflammasome-dependent inflammaging. It is crucial to note that traditional Chinese medicine (TCM) has been identified as an effective countermeasure. The multi-compound therapeutics of TCM simultaneously target oxidative stress, inflammatory fibrosis, and cell death pathways, thereby restoring cardiovascular homeostasis. By combining environmental toxicology and geroprotection research, this work establishes TCM's holistic approach as a paradigm-shifting intervention against the cardiovascular aging caused by plastic pollution, providing practical strategies to address a mounting public health crisis.

Nanoplastics causes heart aging/myocardial cell senescence through the Ca2+/mtDNA/cGAS-STING signaling cascade
Researchers discovered that nanoplastics can cause heart aging by entering heart muscle cells and triggering a chain reaction: they damage mitochondria (the cell's energy source), which leaks DNA into the cell, activating an immune alarm system called the cGAS-STING pathway. This is the first study to reveal how long-term nanoplastic exposure could accelerate heart aging, raising concerns about the cardiovascular effects of plastic pollution.
Microplastics induce mitochondrial dysfunction and accelerate cardiovascular pathogenesis
Researchers reviewed evidence that micro- and nanoplastics detected in human cardiovascular tissues may contribute to cardiovascular disease through mitochondrial dysfunction. The study found that these particles can impair mitochondrial integrity, induce oxidative stress, disrupt calcium signaling, and promote genomic instability, suggesting a mechanistic link between plastic particle exposure and cardiovascular pathology.
Micro- and Nanoplastics Exposure Across the Lifespan: One Health Implications for Aging and Longevity
Researchers reviewed evidence on micro- and nanoplastic exposure across the human lifespan through a One Health lens, finding that MNPs trigger oxidative stress, inflammation, mitochondrial dysfunction, and cellular senescence—mechanisms central to aging—and that older adults face compounded risk from lifetime accumulation and diminished physiological resilience, though direct epidemiological data in this population remain sparse.
Impact of microplastics and nanoplastics on cardiovascular health
This review examines the emerging evidence on how microplastics and nanoplastics may affect cardiovascular health. The study discusses clinical evidence suggesting that these particles can accumulate in the cardiovascular system and highlights possible molecular mechanisms including inflammation and oxidative stress, while noting that current evidence linking microplastics to cardiovascular disease remains largely correlative.
Insights into the toxicological effects of nanomaterials on atherosclerosis: mechanisms involved and influence factors
Researchers reviewed how nanomaterials — tiny engineered particles including nanoplastics — can trigger or worsen atherosclerosis, the buildup of fatty plaques in arteries that leads to heart attacks and strokes. The review found that nanomaterials can damage the cells lining blood vessels and provoke chronic inflammation, raising concerns about the cardiovascular risks of widespread nanomaterial exposure.
