In this study, we assessed the toxicological responses to mechanically (mCF) and thermo-mechanically treated PAN-based carbon fibers (tmCF), applied to BEAS-2B mono-, BEAS-2B/dTHP-1 co-, and BEAS-2B/dTHP-1/CCD-33Lu triple-cultures at an air–liquid interface. The results emphasize the need to further characterize the hazard of CF and the importance of determining exposure levels at workplaces as well as safety measures during the use of CF-containing materials. Moreover, the development and application of more complex in vitro models of the human lung help to establish new approach methodologies in the general field of particle and fiber toxicology and contribute to a reduction in in vivo investigations in the context of the 3R initiative.

Rescue of Ciliary Function in Cell-based Primary Ciliary Dyskinesia Models using Nebulized, LNP-formulated mRNA ReCode Therapeutics is developing an mRNA-based therapy for the treatment of PCD caused by mutations in DNAI1. The DNAI1 mRNA is sequence optimized and formulated in a proprietary SORT lipid nanoparticle (LNP). The LNP formulated mRNA is nebulized and delivered as an aerosol directly into the airway by using a VITROCELL® Cloud 12. Using knockdown human bronchial epithelial (hBE) cultures and knockout mouse tracheal cultures we show that ReCode’s LNP can restore ciliary activity.

VITROCELL® sQCM 12: Data Interpretation

The Quartz Crystal Microbalance is a powerful tool for dosimetry in VITROCELL Exposure Systems. However, interpreting live-data from a sQCM can be misleading, as there is a lot going on in parallel during measurements.

  • BEAS-2B cells were successfully exposed at ALI to primary UFPs emissions
  • PAHs-rich UFPs induced an acute cellular toxicity at low exposed dose
  • PAHs-rich UFPs activated oxidative stress and xenobiotic metabolism
  • This methodological approach offers new perspectives to evaluate different kinds of UFPs

NAM-based prediction of point-of-contact toxicity in the lung: A case example with 1,3-dichloropropene

This case study has implemented a NAM-based chemical risk assessment approach that uses in vitro and in silico methods to account for pharmacodynamic and pharmacokinetic factors of in vivo toxicity. The experiments were performed with the immortalized cell lines A549 and BEAS-2B, of human alveolar and bronchial origin, respectively, to identify a dose range likely to produce a toxic effect in the differentiated cultures. A549 and BEAS-2B cells, grown at the ALI on Transwell permeable supports, were exposed to vapor for 4 h in a Vitrocell 12/12 exposure system, and viability was assessed 24 h after the initiation of exposure.

Dynamic Fluid Flow Exacerbates the (Pro-)Inflammatory Effects of Aerosolised Engineered Nanomaterials In Vitro

In Vitro Toxicology Group, Swansea University Medical School, Swansea University, Wales SA2 8PP, UK

The aim of this study was to develop further an established static in vitro model used to test ENP aerosol toxicology to incorporate fluid-flow dynamics. This was achieved by implementing the QuasiVivoTM system with a characterised A459_dTHP-1 coculture exposed in the Vitrocell Cloud12 to different particle samples at the ALI.

This study aimed at testing the robustness and sensitivity, characterizing, and optimizing an advanced respiratory model built on human alveolar epithelial A549 cells and evaluating its response to aerosol exposure of silver NM-300K. In more detail, we compared the responses of A549 cells cultured at the ALI in the VITROCELL® 6 Cloud system in monoculture, in coculture with EA.hy926 cells, and in triculture with EA.hy926 cells and dTHP-1, and performed an interlaboratory trial across two laboratories.
