Over the past two decades, significant progress has been made in establishing the fundamentals of nanotoxicology, which has improved our understanding of ENM toxicity particularly regarding their physicochemical properties (e.g. size, shape, surface charge). Furthermore, substantial efforts have been devoted to elucidating the molecular mechanisms underlying nano-bio interactions, which are not only important for understanding health risks but are also critical for advancing therapeutic applications. However, the assessment of ENM adverse responses at low and subtoxic exposure levels, chronically or within specific contexts (e.g. co-exposure to other toxicants) has not received much attention. This is particularly important as real-world exposure to ENMs (e.g. occupational, medicinal, consumer products) typically occurs at low exposure levels, over long periods of time, in the presence of other exposures or preexisting disease. Accumulating research is demonstrating that even in the absence of overt toxicity, exposure to ENMs may contribute to adverse health outcomes, including exacerbation of co-toxicities and co-diseases. This underscores the critical need for evaluating ENM-induced adverse responses beyond conventional toxicological endpoints which are often carried out at unrealistically high doses. In this review article, we discuss the current state of the literature and highlight key emerging findings demonstrating adverse consequences of ENM exposure at low and subtoxic levels. We also discuss current challenges and future directions to address existing knowledge gaps.</p>","PeriodicalId":18899,"journal":{"name":"Nanotoxicology","volume":" ","pages":"1-21"},"PeriodicalIF":3.6,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the toxicity of lanthanum oxide (La₂O₃) and yttrium oxide (Y₂O₃) nanoparticles (NPs) and bulk forms on <i>Folsomia candida</i>. Single (0-2500 mg/kg) and dual mixture exposures were tested for effects on survival, reproduction, avoidance behavior, and biochemical markers. No effects on survival and avoidance behavior were observed. NPs were more toxic than bulk forms. La₂O₃ NPs reduced reproduction (≥ 1250 mg/kg) and acetylcholinesterase (AChE) activity (2500 mg/kg), whereas Y₂O₃ NPs exhibited greatest toxicity, reducing reproduction (≥ 313 mg/kg) and increasing catalase (CAT) (156 and 625 mg/kg) and glutathione reductase (GR) (625 and 2500 mg/kg) activities. Mixture exposures revealed complex interactions (synergism, antagonism, or no interaction), with toxicity depending on concentration, endpoint, and material form. Besides, higher number of biochemical endpoints were affected by mixture exposures, but dissimilar responses were observed with different concentrations: 2500 mg/kg Y₂O₃ NPs + 2500 mg/kg La₂O₃ NPs decreased reproduction and increased GR, glutathione S-transferases (GST) and AChE activities; 2500 mg/kg Y₂O₃ NPs + 625 mg/kg La₂O₃ NPs increased CAT, GR, GST and AChE activities; 625 mg/kg Y₂O₃ NPs + 625 mg/kg La₂O₃ NPs increased GR activity; 156 mg/kg Y₂O₃ NPs + 2500 mg/kg La₂O₃ NPs decreased AChE activity, increased GR activity and lipid peroxidation levels.

The toxicity of these structures, classified as contaminants of emerging concern, is not yet sufficiently understood. However, as in the case of other environmental stressors, the effects of exposure to them should be analyzed on a multigenerational scale to predict the consequences for exposed populations. Therefore, this project aimed to assess the impact of graphene oxide (GO) nanomaterial on digestive enzyme activities in the house cricket <i>Acheta domesticus</i> as a model species, depending on GO concentration (0.2 or 0.02 µg·g^-1dry weight of food), previous selection for longevity and the number of generations (1-5) that have occurred since the beginning of exposure. The last and sixth generations were insects for which GO was withdrawn from the diet (recovery generation). Enzymatic activity was tested using API Zym kit modified for spectrophotometric reads. The tests revealed that GO intervenes with some digestive enzymes. Moreover, the effects of GO depend on the population's previous selection for longevity. The impact of mechanisms mitigating the consequences of aging supports the possible tolerance to GO intoxication. It demonstrated itself in diverse patterns of multigenerational response to GO in wild and long-lived insects. Also, multigenerational exposure revealed the 'third generation' effect. Finally, the impact of GO elimination depended on the concentration of nanomaterial used for the tests. Also, the potential impact of concentration-dependent agglomeration of GO in the context of hormesis has been discussed.</p>","PeriodicalId":18899,"journal":{"name":"Nanotoxicology","volume":" ","pages":"1-14"},"PeriodicalIF":3.6,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144079245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the primary cause of adult tooth loss is periodontitis, one of the most common dental disorders worldwide. The key to preventing periodontitis has been to reduce the development of bacteria and the generation of substances that eventually erode the tissue surrounding and supporting the teeth. Furthermore, there are several disadvantages to treating periodontitis with antibiotics administered systemically. A naturally occurring polymer with antibacterial and anti-inflammatory properties is chitosan (CS). CS is highly interested in treating periodontal disease as a medicine carrier due to its actions against anaerobic microorganisms and possible anti-inflammatory properties. Due to the multifactorial pathophysiology of periodontitis, combining antimicrobial medications in a single drug delivery method is preferable to administering them separately since it increases the therapeutic range when numerous organisms are present. As a result, CS-based drug delivery technologies, such as gels, micro, and nanoparticles (NPs), were created to transport drugs to the periodontal pocket over an extended period.

Many in vitro studies have shown that exposure to engine exhaust can induce oxidative stress in lung cells, leading to cellular inflammation and cytotoxicity. However, it remains challenging to identify key harmful components and their specific adverse effects via traditional toxicological assessments. Machine learning (ML) methods offer new ways of analyzing such complex datasets and have gained attention in predicting toxicity outcomes and identifying key pollutants in mixtures responsible for adverse effects in a non-biased way. This study aims to understand the contribution of exhaust components to lung cell toxicity using ML techniques. Data were reanalyzed from previous studies (2015-2018), where a 3D human epithelial airway tissue model was exposed to gasoline and diesel engine exhausts under air-liquid interface (ALI) conditions with different fuels and exhaust after-treatment systems. This dataset included exhaust characteristics (particle number (PN), carbon monoxide (CO), total gaseous hydrocarbons (THC), and nitrogen oxides (NO<i>x</i>) levels) and corresponding biological responses (cytotoxicity, oxidative stress, and inflammatory responses). The relationships between pollutants and biological responses were explored using ML techniques, including hierarchical and nonhierarchical clustering and principal component analysis. The findings reveal both gaseous (CO, THC, and NO<i>x</i>) and particulate pollutants contribute to oxidative stress, inflammation, and cytotoxicity in lung cells, highlighting the significant role of each gaseous component. In addition, unmeasured factors beyond CO, THC, NO<i>x</i>, and PN likely contribute to biological effects, indicating the need for a more detailed characterization of exhaust parameters in ML analysis. By successfully integrating ML techniques, this study shows the potential of ML in identifying pollutant-specific contributions to cell toxicity.
