| Research Abstract |
Increased incidence of asthma and other allergic diseases are the worldwide problem. Air-pollution is recognized as one of the important factor for pathogenesis of asthma. We have investigated whether exposure to air-pollution such as oil fly as, formaldehyde and tobacco smoking during pregnancy can contribute to development of asthma in the offspring. Data indicated neonatal mice from mothers exposed to pollutants before delivery could express asthma manifestation by the suboptimal sensitization. As the mechanism(s), these mice showed the persistent Th2-dominant immune profile after birth. Contribution of epigenetics to this maternal transmission or transplacental effect of asthma susceptibility should be clarified.
