In vitro three-dimensional (3D) lung cell models have been thoroughly investigated in recent years and provide a reliable tool to assess the hazard associated with nanomaterials (NMs) released into the air. In this study, a 3D lung co-culture model was optimized to assess the hazard potential of multiwalled carbon nanotubes (MWCNTs), which is known to provoke inflammation and fibrosis,...

A large number of prevalent lung diseases is associated with tissue inflammation. Clinically, corticosteroid therapies are applied systemically or via inhalation for the treatment of lung inflammation, and a number of novel therapies are being developed that require preclinical testing. In alveoli, macrophages and dendritic cells play a key role in initiating and diminishing pro-inflammatory...

Impact of airborne particulate matter on skin: a systematic review from epidemiology to in vitro studies

Dijkhoff, Irini M. ; Drasler, Barbara ; Karakocak, Bedia Begum ; Petri-Fink, Alke ; Valacchi, Giuseppe ; Eeman, Marc ; Rothen-Rutishauser, Barbara

Air pollution is killing close to 5 million people a year, and harming billions more. Air pollution levels remain extremely high in many parts of the world, and air pollution- associated premature deaths have been reported for urbanized areas, particularly linked to the presence of airborne nano-sized and ultrafine particles.Main text: To date, most of the research studies did focus on the...
