Air-liquid interface In Vitro models for respiratory toxicology research: Consensus workshop and recommendations
article
In vitro air–liquid interface (ALI) cell culture models can potentially be used to assess inhalation toxicology endpoints and are usually considered, in terms of relevancy, between classic (i.e., submerged) in vitro models and
animal-based models. In some situations that need to be clearly defined, ALI methods may represent a complement
or an alternative option to in vivo experimentations or classic in vitro methods. However, it is clear that
many different approaches exist and that only very limited validation studies have been carried out to date.
This means comparison of data from different methods is difficult and available methods are currently not suitable
for use in regulatory assessments. This is despite inhalation toxicology being a priority area for many governmental
organizations. In this setting, a 1-day workshop on ALI in vitro models for respiratory toxicology
research was organized in Paris in March 2016 to assess the situation and to discuss what might be possible
in terms of validation studies. The workshop was attended by major parties in Europe and brought together
more than 60 representatives from various academic, commercial, and regulatory organizations. Following plenary,
oral, and poster presentations, an expert panel was convened to lead a discussion on possible approaches to
validation studies for ALI inhalation models. A series of recommendations were made and the outcomes of the
workshop are reported.
