Project description:In this study, we modeled early life air pollution exposure using C57BL/6J male mice on a controlled chow diet, exposed to real-world inhaled concentrated PM2.5 (~10x ambient level/ ~60-120g/m3) or filtered air (FA) over 14 weeks. We investigated PM2.5 effects on phenotype, transcriptome and chromatin accessibility, compared the effects with a prototypical high-fat diet (HFD) stimulus, and examined the effects of cessation of exposure on reversibility of phenotype/genotype.
Project description:BEAS-2B cells, at air-liquid interface, were exposed to Diesel CAST model aerosol in an vitro exposure system and, later, to native birch pollen using a Pollen Sedimentation Chamber stabilished before. The same exposure was performed, without the primed anthropogenic exposure. The goal was to understand the effect of pre-exposure to a model diesel aerosol in allergic sensitization, using a model stabilished that mimics a real life exposure as closer as possible.
