Characterization of detrimental effects of genetic and environmental factors on the brain and to develop treatments to antagonize these effects. For the genetic factor, we particularly study the isoform-dependent effects of apoE. The three major human apoE isoforms (apoE2, apoE3, and apoE4) differ in their risk to develop cognitive impairments with age and following environmental challenges. As environmental factors, we focus on cognitive impairments due to exposure of the adult brain to radiation.
