Abstract
Research on the toxicity of engineered carbon nanotubes (CNT) was initiated by Belgian academic chemists and toxicologists more than 15 years ago. It is now undisputed that some of these attractive nanomaterials induce serious illness such as fibrosis and cancer. The physico-chemical determinants of CNT-induced adverse effects are now elucidated and include shape, nanoscale diameter, and structural defects. Generated in vitro and in vivo data on their inflammogenic and fibrogenic activities were combined and translated in AOP (adverse outcome pathways) available for risk assessment and regulatory policies. The asbestos-like carcinogenic effect of CNT, notably their capacity to induce malignant mesothelioma (MM), remain, however, a cause of concern for public health and strongly curb the craze for CNT in industries. MM still represents a real challenge for clinicians and a highly refractory cancer to existing therapeutic strategies. By comparing mesotheliomagenic CNT (needle-like CNT-N) to non mesotheliomagenic CNT (tangled-like CNT-T), our group generated a relevant animal model that highlights immune pathways specifically associated to the carcinogenic process. Evidence indicates that only CNT-N possess the intrinsic capacity to induce a preferential, rapid, and sustained accumulation of host immunosuppressive cells that subvert immune surveillance and suppress anti-mesothelioma immunity. This new concept offers novel horizons for the clinical management of mesothelioma and represents an additional tool for predicting the mesotheliomagenic activity of newly elaborated CNT or nanoparticles.

Abstract
Carbon nanotubes (CNTs) are promising biomaterials in the medical field, especially in tissue engineering of bone. However, the use of CNTs is largely confined by its unfavorable solubility and toxicity. To improve solubility and biocompatibility of CNTs, functionalization has been proven to be an effective strategy. Although various functionalized CNTs have been extensively studied, only few CNTs have the desired qualities. We compared the toxicity of several promising functionalized multi-walled carbon nanotubes (MWCNTs) on rat bone-marrow derived stem cells (BMSCs). Cell experiments showed that while acid oxidation (AO)-MWCNTs and Raw-MWCNTs exhibited significant toxicity on BMSCs, polyethylene glycols (PEG)-MWCNTs and hydroxyapatit (HA)-MWCNTs had favorable biocompatibility and a trivial effect on BMSCs. Possible mechanisms for the cytotoxicity on BMSCs included mitochondrisome and deoxyribonucleic acid damage, increased oxidative stress and damaging of cellular membranes. Our data indicated that PEG-MWCNTs and HA-MWCNTs may be promising materials for bio-related applications.

Evaluating the mechanistic evidence and key data gaps in assessing the potential carcinogenicity of carbon nanotubes and nanofibers in humans. Crit Rev Toxicol 2017; 47:1-58.

Abstract
In an evaluation of carbon nanotubes (CNTs) for the IARC Monograph 111, the Mechanisms Subgroup was tasked with assessing the strength of evidence on the potential carcinogenicity of CNTs in humans. The mechanistic evidence was considered to be not strong enough to alter the evaluations based on the animal data. In this paper, we provide an extended, in-depth examination of the in vivo and in vitro experimental studies according to current hypotheses on the carcinogenicity of inhaled particles and fibers. We cite additional studies of CNTs that were not available at the time of the IARC meeting in October 2014, and extend our evaluation to include carbon nanofibers (CNFs). Finally, we identify key data gaps and suggest research needs to reduce uncertainty. The focus of this review is on the cancer risk to workers exposed to airborne CNT or CNF during the production and use of these materials. The findings of this review, in general, affirm those of the original evaluation on the inadequate or limited evidence of carcinogenicity for most types of CNTs and CNFs at this time, and possible carcinogenicity of one type of CNT (MWCNT-7). The key evidence gaps to be filled by research include: investigation of possible associations between in vitro and early-stage in vivo events that may be predictive of lung cancer or mesothelioma, and systematic analysis of dose-response relationships across materials, including evaluation of the influence of physico-chemical properties and experimental factors on the observation of nonmalignant and malignant endpoints.

Abstract
Due to their unique physicochemical properties, the potential health effects of single-walled carbon nanotubes (SWCNTs) have attracted continuous attention together with their extensive application. In this study, we aimed to identify local and systemic health effects following pulmonary persistence of SWCNTs. As expected, SWCNTs remained in the lung for 13 weeks after a single intratracheal instillation (50, 100, and 200μg/kg). In the lung, the total number of cells and the percentages of lymphocytes and neutrophils significantly increased at 200μg/kg compared to the control, and the Th1-polarized immune response was induced accompanying enhanced expression of tissue damage-related genes and increased release of chemokines. Additionally, SWCNTs enhanced the expression of antigen presentation-related proteins on the surface of antigen-presenting cells, however, maturation of dendritic cells was inhibited by their persistence. As compared to the control, a significant increase in the percentage of neutrophils and a remarkable decrease of BUN and potassium level were observed in the blood of mice treated with the highest dose. This was accompanied by the down-regulation of the expression of antigen presentation-related proteins on splenocytes. Moreover, protein and glucose metabolism were disturbed with an up-regulation of fatty acid β-oxidation. Taken together, we conclude that SWCNTs may induce adverse health effects by disturbing immune and metabolic regulation functions in the body. Therefore, careful application of SWCNTs is necessary for the enforcement of safety in nano-industries.

Abstract
Nanotoxicology aims to study the safety of nanomaterials, especially towards human exposure. Biodegradable polymeric nanocapsules have been indicated as potential drug carriers applicable for treating several pathologies. Thus, the objective of this study was to evaluate the potential cardiotoxicity of biodegradable lipid-core nanocapsules (LNC) containing poly(ε-caprolactone). Nanocapsules were characterized and the acute toxicity evaluation was conducted in Wistar rats. Two control groups (saline and tween/glycerol) were utilized, and three treated groups were chosen for low, intermediate and high doses: 28.7 × 1012 (LNC-1), 57.5 × 1012 (LNC-2) and 115 × 1012 (LNC-3), expressed as number of nanocapsules per milliliter per kg. Blood pressure measurements were performed in non-anesthetized animals by caudal plethysmography. The electrocardiographic (ECG) and echocardiographic analyses were carried out after anesthesia by isoflurane at two points, prior to treatment and after 14 days. Blood was collected 24 hours and 14 days after treatment. Biochemical and histopathological analyses were performed. During the evaluation period, no deaths, weight loss or clinical signs were observed. Post-treatment systolic pressures (24 h and 14 days) were significantly increased in comparison to pre-treatment in both control groups and treated groups, which is suggested to be as a possible consequence of the infused volume. Serum sodium, potassium, aspartate aminotransferase and alkaline phosphatase, as well as, hematological parameters were within reference values established for rats. ECG showed no indications of cardiotoxicity. Despite the echocardiograms, no alterations in the ejection fraction were found as indicators of cardiotoxicity. Cardiac histopathology also demonstrated no alterations. Therefore, the present results on acute evaluation after i.v. administration, by slow infusion, showed potential safety since no cardiotoxic effects by ECG, echocardiographic, arterial pressure, biochemical and histopathological analyses were found.

Abstract
A rapid increase in utility of engineered nanomaterials, including carbon nanotubes (CNTs), has raised a concern over their safety. Based on recent evidence from animal studies, pulmonary exposure of CNTs may lead to nanoparticle accumulation in the deep lung without effective clearance which could interact with local lung cells for a long period of time. Physicochemical similarities of CNTs to asbestos fibers may contribute to their asbestos-like carcinogenic potential after long-term exposure, which has not been well addressed. More studies are needed to identify and predict the carcinogenic potential and mechanisms for promoting their safe use. Our previous study reported a long-term in vitro exposure model for CNT carcinogenicity and showed that 6-month sub-chronic exposure of single-walled carbon nanotubes (SWCNT) causes malignant transformation of human lung epithelial cells. In addition, the transformed cells induced tumor formation in mice and exhibited an apoptosis resistant phenotype, a key characteristic of cancer cells. Although the potential role of p53 in the transformation process was identified, the underlying mechanisms of oncogenesis remain largely undefined. Here, we further examined the gene expression profile by using genome microarrays to profile molecular mechanisms of SWCNT oncogenesis. Based on differentially expressed genes, possible mechanisms of SWCNT-associated apoptosis resistance and oncogenesis were identified, which included activation of pAkt/p53/Bcl-2 signaling axis, increased gene expression of Ras family for cell cycle control, Dsh-mediated Notch 1, and downregulation of apoptotic genes BAX and Noxa. Activated immune responses were among the major changes of biological function. Our findings shed light on potential molecular mechanisms and signaling pathways involved in SWCNT oncogenic potential.

Abstract
Rapid growth in nanotechnology has raised concerns regarding adverse health effects due to human exposure to manufactured nanoparticles. Carbon nanotubes (CNT) are among the most extensively used nanoparticles. This study examined pulmonary and atherosclerotic effects of multiwalled CNT (MWCNT) in a mouse model of atherosclerosis. Female apolipoprotein E-deficient (apoE-/-) mice were exposed to 40 μg MWCNT, once each week for 16 consecutive weeks by pharyngeal aspiration. On d 1 after the last administration, tissues were extracted from half the group, while the remaining animals were sacrificed at d 7. Bronchoalveolar lavage (BAL) was performed to obtain BAL fluid. In addition, plasma, lung, and aortas were extracted to assess pulmonary inflammation and atherosclerotic lesion formation. Polymorphonuclear leukocytes and total BAL cell number increased significantly in MWCNT-exposed mice on d 1 and 7 postexposure. Cell-free BAL fluid obtained from MWCNT-exposed mice at d 1 and 7 postexposure contained significantly elevated levels of total protein, lactate dehydrogenase (LDH), surfactant protein-D, and mucin. Although MWCNT exposure increased pulmonary injury and inflammation, the aortic intimal surface covered by atherosclerotic lesions was not significantly different between control apoE-/- mice and apoE-/- MNCNT-treated animals. Total plasma cholesterol concentrations also were not markedly affected by MWCNT exposure. These results demonstrate that pulmonary exposure to MWCNT affects local airway inflammation but did not appear to augment progression of atherosclerosis in female apoE-/- mice.

Abstract
In this study, we identified the toxic response of pristine single-walled carbon nanotubes (P-SWCNTs) synthesized by HIPCO method in mice and RAW264.7 cells, a murine peritoneal macrophage cell line. P-SWCNT contained a large amount of Fe ion (36 wt%). In the lungs of mice 24 h after intratracheal administration, P-SWCNTs increased the secretion of IL-6 and MCP-1, and the number of total cells, the portion of neutrophils, lymphocytes, and eosinophils, also significantly increased at a 100 μg/mL of concentration. In RAW264.7 cells, cell viability and ATP production decreased in a dose-dependent manner at 24 h after exposure, whereas the generations of ROS and NO were enhanced at all concentrations together with the activation of the MAP kinase pathway. Moreover, the levels of both apoptosis- and autophagy-related proteins and ER stress-related proteins clearly increased, and the concentrations of Fe, Cu, and Zn ions, but not of Mn ions, increased in a dose-dependent manner. TEM images also revealed that P-SWCNTs induced the formation of autophagosome-like vacuoles, the dilatation of the ER, the generation of mitochondrial flocculent densities, and the separation of organelle by disappearance of the cell membrane. Taken together, we suggest that P-SWCNTs cause acute inflammatory response in the lungs of mice, and induce autophagy accompanied with apoptosis through mitochondrial dysfunction and ER stress in RAW264.7 cells. Furthermore, further study is required to elucidate how the physicochemical properties of SWCNTs determine the cell death pathway and an immune response.

Abstract
Single-wall carbon nanotubes (SWCNT) possess a small size, large surface area, and high reactivity, which enable them to permeate the cytoplasmic or nuclear membrane and attach to biological molecules. During medical applications, SWNCT are usually administered intravenously, which enhances interaction with blood components. Yet despite this exposure potential, safety evaluation studies of SWCNTs focused on human blood cells are still lacking. Therefore, this study was undertaken to examine cytotoxicity, genotoxicity, and proinflammatory responses following SWCNT treatment of phytohemagglutinin (PHA)-stimulated male human peripheral blood lymphocytes (PBL). SWCNT were found to inhibit cell growth, as well as to induce DNA breakage, and micronuclei (MN) formation via reactive oxygen species (ROS) generation. The addition of N-acetylcysteine (NAC) a cell-permeable antioxidant, decreased ROS generation, cytotoxicity, and genotoxicity produced by SWCNT treatment. In addition, SWCNT induced tumor necrosis factor (TNF)-α release after 24 h, yet this phenomenon was not related to ROS generation, as antioxidant NAC treatment did not affect increased proinflammatory cytokine levels in the phytohemagglutinin (PHA)-stimulated male human PBL.

Abstract
Functionalization is an important technique to increase the solubility and biocompatibility of single-wall carbon nanotubes (SWCNTs). In this study, we investigated the cytotoxicity of four types of SWCNTs functionalized with hydroxyl, amino, carboxyl and polyethyleneglycol on MCF7 cells. These functionalized SWCNTs (f-SWCNTs) have insignificant effects on mitochondrial activity and ROS production in MCF7 cells at all test concentrations. However, explicit results revealed that all the tested f-SWCNTs could cause changes of cell morphology, induce cell membrane damage, decrease cell adhesion, and increase cell apoptosis. Therefore, this study shows the potential side effects of f-SWCNTs accompanying with the increase of dispersibility and stability in environment or serum (to prevent their aggregation), and highlights the need for further research to examine the potential toxicity of f-SWCNTs before they are used in the environmental and biomedical fields.

Abstract
The toxicological effects of single-walled carbon nanotubes (SWCNTs) were investigated after intratracheal instillation in male Wistar rats over a 15-day period using metabonomic analysis of 1H (nuclear magnetic resonance) NMR spectra of blood plasma and liver tissue extracts. Concurrent liver histopathology examinations and plasma clinical chemistry analyses were also performed. Significant changes were observed in clinical chemistry features, including alkaline phosphatase, total protein, and total cholesterol, and in liver pathology, suggesting that SWCNTs clearly have hepatotoxicity in the rat. 1H NMR spectra and pattern recognition analyses from nanomaterial-treated rats showed remarkable differences in the excretion of lactate, trimethylamine oxide, bilineurin, phosphocholine, amylaceum, and glycogen. Indications of amino acid metabolism impairment were supported by increased lactate concentrations and decreased alanine concentrations in plasma. The rise in plasma and liver tissue extract concentrations of choline and phosphocholine, together with decreased lipids and lipoproteins, after SWCNTs treatment indicated a disruption of membrane fluidity caused by lipid peroxidation. Energy, amino acid, and fat metabolism appeared to be affected by SWCNTs exposure. Clinical chemistry and metabonomic approaches clearly indicated liver injury, which might have been associated with an indirect mechanism involving nanomaterial-induced oxidative stress.

Abstract
Owing to the development of new materials and technology, the pollutants in the environment are becoming more varied and complex over time. In our previous study using ICR mice, we suggested that a single intratracheal instillation of single-walled carbon nanotubes (SWCNTs) induced early lung fibrosis and subchronic tissue damage. In the present study, to investigate the role of CCR5 in inflammatory responses to the uptake of SWCNTs, we compared BAL (Bronchoalveolar lavage) cell composition, cell cycles, cytokines, cell phenotypes, inflammatory response-related proteins, cell surface receptors and histopathology using CCR5 knockout (KO) and wild-type mice. Results showed that the distribution of neutrophils in BAL fluid significantly decreased in KO mice. The expression of apoptosis-related proteins including caspase-3, p53, phospho-p53, p21 and cleaved PARP, TGF βl and mesothelin markedly increased in KO mice compared with wild-type mice. Histopathological lesions were also more frequently noted in KO mice. Moreover, the secretion of IL-13 and IL-17 with IL-6 significantly increased in KO mice compared with wild-type mice, whereas that of IL-12 significantly decreased in comparison to wild-type mice. The distribution of B cells and CD8+ T cells was predominant in the inflammatory responses in KO mice, whereas that of T cells and CD4+ T cells was predominant in the inflammatory responses in wild-type mice. Furthermore, the expression of CCR4 and CCR7 significantly increased in KO mice. Based on these results, we suggest that the absence of CCR5 delays the resolution of inflammatory responses triggered by SWCNTs inflowing into the lungs and shifts inflammatory response for SWCNTs clearance from Th1-type to Th2-type.

Abstract
Beyond the traditional use of ceria as an abrasive, the scope of nanoceria applications now extends into fuel cell manufacturing, diesel fuel additives, and for therapeutic intervention as a putative antioxidant. However, the biological effects of nanoceria exposure have yet to be fully defined, which gave us the impetus to examine its systemic biodistribution and biological responses. An extensively characterized nanoceria (5 nm) dispersion was vascularly infused into rats, which were terminated 1 h, 20 h or 30 days later. Light and electron microscopic tissue characterization was conducted and hepatic oxidative stress parameters determined. We observed acute ceria nanoparticle sequestration by Kupffer cells with subsequent bioretention in parenchymal cells as well. The internalized ceria nanoparticles appeared as spherical agglomerates of varying dimension without specific organelle penetration. In hepatocytes, the agglomerated nanoceria frequently localized to the plasma membrane facing bile canaliculi. Hepatic stellate cells also sequestered nanoceria. Within the sinusoids, sustained nanoceria bioretention was associated with granuloma formations comprised of Kupffer cells and intermingling CD3⁺ T cells. A statistically significant elevation of serum aspartate aminotransferase (AST) level was seen at 1 and 20 h, but subsided by 30 days after ceria administration. Further, elevated apoptosis was observed on day 30. These findings, together with increased hepatic protein carbonyl levels on day 30, indicate ceria-induced hepatic injury and oxidative stress, respectively. Such observations suggest a single vascular infusion of nanoceria can lead to persistent hepatic retention of particles with possible implications for occupational and therapeutic exposures.
