Description:
Objective:The goals of this project are to establish in vivo exposure models in mice and primates with which to study how relevant xenobiotics of concern to childhood autism influence the development of social behavior. The specific aims of the mouse studies were to: (1) develop a battery of behavioral probes to assess social behavior in developing and mature mice, (2) to evaluate the effects of prenatal and early postnatal exposure to thimerosal, methyl mercury and congeners of PCB on the emergence and quality of social behavior in mice, (3) to determine whether the expected toxicity of exposure to xenobiotics is altered in mice whose immune systems have been activated early in postnatal development by administration of bacterial endotoxin lipopolysaccaride (LPS), and (4) to examine selected brain regions (e.g., amygdala) in xenobiotic treated mice for morphological alterations that may be similar to those observed in neuropathological studies of autism.
The aim of the monkey studies were to use a battery of social testing to evaluate potential alterations of conspecific social behavior following early postnatal exposure of realistic levels of thimerosal, methyl mercury and congeners of PCB.
