General description

Dibutyl phthalate (DBP) is most commonly used as a plasticizer in a variety of household products. It has the ability to leach and evaporate into the environment while using or disposing of these products. Therefore, studies are being conducted to assess its toxic and apoptotic effects. Studies have also indicated that exposure to high doses of DBP may interfere with progesterone and estradiol production.

Dibutyl phthalate (DBP)-induced apoptosis and neurotoxicity are mediated via the aryl hydrocarbon receptor (AhR) but not by estrogen receptor alpha (ER?), estrogen receptor beta (ER?), or peroxisome proliferator-activated receptor gamma (PPAR?) in mouse cortical neurons.

Assays to monitor the metabolic state or nutrient uptake capacity of immune cells at a single cell level are increasingly in demand. One assay, used by many immunologists, employs 2-(N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)Amino)-2-Deoxyglucose (2-NBDG), a fluorescent analogue of 2-deoxyglucose (2DG), as a substrate
