Perinatal Gene-Gene and Gene-Environment Interactions on IgE Production and Asthma Development

الملخص EN

Atopic asthma is a complex disease associated with IgE-mediated immune reactions.

Numerous genome-wide studies identified more than 100 genes in 22 chromosomes associated with atopic asthma, and different genetic backgrounds in different environments could modulate susceptibility to atopic asthma.

Current knowledge emphasizes the effect of tobacco smoke on the development of childhood asthma.

This suggests that asthma, although heritable, is significantly affected by gene-gene and gene-environment interactions.

Evidence has recently shown that molecular mechanism of a complex disease may be limited to not only DNA sequence differences, but also gene-environmental interactions for epigenetic difference.

This paper reviews and summarizes how gene-gene and gene-environment interactions affect IgE production and the development of atopic asthma in prenatal and childhood stages.

Based on the mechanisms responsible for perinatal gene-environment interactions on IgE production and development of asthma, we formulate several potential strategies to prevent the development of asthma in the perinatal stage.
