Several epidemiological and experimental studies indicate a positive association between exposure to formaldehyde or phthalates and allergic asthma. However, nothing is yet known about the effects of exposure to for-maldehyde and phthalates together, nor the role of each on allergic asthma. Here, we investigated the effects of a combined exposure to formaldehyde and diisononyl phthalate (DINP) on asthma-like pathology in mice, and determined the underlying mechanisms implicated in NF-kappa B and ROS. Mice were exposed to formaldehyde and/or DINP and sensitization with OVA. The results showed t...
