The presence of microplastics (MPs) is increasing at a dramatic rate globally, posing risks for exposure and subsequent potential adverse effects on human health. Apart from being physical objects, MP particles contain thousands plastic-associated chemicals (i.e., monomers, chemical additives, non-intentionally added substances) captured within the polymer matrix. These are often migrating MPs can be found in various environmental matrices food chains; health effects. In addition to attributes MPs, plastic surfaces effectively bind exogenous chemicals, including pollutants (e.g., heavy metals, persistent organic pollutants). Therefore, act as vectors pollution across air, drinking water, food, further amplifying posed by exposure. Critically, fragmentation plastics environment increases risk interactions with cells, available leach adsorb transfer pollutants. This review proposes so-called triple nexus approach comprehensively map existing knowledge interconnected particles, Based data, there large gap regard cumulative nexus. Each component known induce genotoxicity, inflammation, endocrine disruption, but about long-term inter-individual lacking. Furthermore, not readily excreted organisms after ingestion they have been accumulated blood, cardiac tissue, placenta, etc. Even though number studies MPs-associated impacts rapidly, this underscores that pressing necessity achieve an integrated assessment MPs' order address future gaps.

Molecular and Cellular Effects of Microplastics and Nanoplastics: Focus on Inflammation and Senescence

Cells, Год журнала: 2024, Номер 13(21), С. 1788 - 1788

Опубликована: Окт. 29, 2024

Microplastics and nanoplastics (MNPs) are ubiquitous environmental contaminants. Their prevalence, persistence, increasing industrial production have led to questions about their long-term impact on human animal health. This narrative review describes the effects of MNPs oxidative stress, inflammation, aging. Exposure leads increased reactive oxygen species (ROS) across multiple experimental models, including cell lines, organoids, systems. ROS can cause damage cellular macromolecules such as DNA, proteins, lipids. Direct interaction between immune cells or an indirect result stress-mediated may lead pro-inflammatory cytokines throughout different MNP-exposure conditions. inflammatory response is a common feature in pathogenesis neurodegenerative, cardiovascular, other age-related diseases. also act senescence inducers by promoting mitochondrial dysfunction, impairing autophagy, activating DNA responses, exacerbating aging altogether. Increased reproductive transfer MNPs/induced damages from parents offspring animals further corroborates transgenerational health risks tiny particles. aims provoke deeper investigation into notorious these pervasive particles well-being longevity.

Microplastic exposure has become unavoidable, leading to their presence in living organisms. One area of particular concern is the genotoxicity microplastics, which implications for reproductive health and cancer development. This review aims highlight genotoxic effects microplastics on different organisms, focusing impacts chromosomes, DNA, gene expression. More than 85 papers, primarily published last five years, have been reviewed. indicates that can cause clastogenesis aneugenesis at chromosome level. Clastogenesis results damage, while leads failures segregation without causing direct damage. Additionally, fracture damage DNA. These arise from (1) through interactions with associated proteins; (2) indirect due production reactive oxygen species (ROS) by oxidative stress induced microplastics. Microplastics trigger activation genes related inflammatory response, increased ROS production. Furthermore, they may alter expression other biological processes. The linked stem particles themselves chemicals, it appears be both size- dose-dependent.
