| Outline of Final Research Achievements |
Sick building syndrome (SBS) is a set of several clinically recognizable symptoms reported by occupants of a building without a clear cause. Neuropathy target esterase (NTE) is a membrane bound serine esterase and its reaction with organophosphates (OPs) can lead to OP-induced delayed neuropathy (OPIDN) and nerve axon degeneration. We found that the enzymatic activity of NTE was significantly higher (P<0.0005) in SBS patients compared with controls. Thus, we constructed the transgenic(TG) mice with PNPLA6 gene encoding human NTE. Eight lines were established and each mouse from 8 lines showed higher activity for NTE than that in non transgenic mouse. The activity level was different in each tissue and the activity became higher in the old TG mice than that in the young TG mice. To elucidate the effect of OP for these mice, the experiments are now on going and the preliminary data showed harmful effects of OP for transgenic embryos. In addition, we try to detect the NTE-OP complex.
