Pregnancy Over 40, Fetal Antibodies and AutismIt seems like everytime I turn around, I'm reading something new about autism and esearch.
Here is an article taht talks about how the mother's antibodies may lead to brain inflammation in the baby. Read more:
From the article:
A report on the research from investigators at the Johns Hopkins Children's Center published online in the Journal of Neuroimmunology expands on a 2008 report from the same team showing that mothers of autistic children tested positive for fetal brain antibodies. Antibodies are proteins the body naturally makes to attack foreign tissues, viruses or bacteria.
Because a growing fetus is not "rejected" by the mother's immune system even though some of its DNA is "foreign" (from the father), scientists have long suspected that some combination of maternal and fetal biological protection is at work. The new research from Hopkins, however, suggests that the protective system is not perfect and that antibodies are not only made but are re-circulated back to the fetus through the placenta, possibly triggering inflammation in the brain and leading to a cascade of neurological changes resulting in neurodevelopmental disorders, such as autism.
