6.  Neurotoxic Effects of Postnatal Thimerosal are Mouse Strain Dependent.
Molecular Psychiatry, Sep 2004.
Mady Hornig, MD [Columbia University].
This recent work by Columbia University Doctors explores whether genes are important in determining if mercury exposures akin to those in childhood immunizations can disrupt brain development and function. It is the first known scientific study done specifically on ethlymercury administered in a way similar to the vaccine schedule. Dr. Hornig discussed the study before Congress in September 2004. Excerpt:
"The premise of our research is that if mercury in vaccines creates risk for neurodevelopmental disorders such as autism, genetic differences are likely to contribute to that risk. Earlier studies, however, did not use the form of mercury present in vaccines, known as thimerosal, and did not consider whether intramuscular, repetitive administration during early postnatal development, when the brain and immune systems are still maturing, might intensify toxicity. Our predictions were confirmed. Using thimerosal dosages and timing that approximated the childhood immunization schedule, our model of postnatal thimerosal neurotoxicity demonstrated that the genes in mice that predict mercury-related immunotoxicity also predicted nuerodevelopmental damage. Features reminiscent of those observed in autism occurred in the mice of the genetically sensitive strain."
7.  Activation of Methionine Synthase by Insulin-like Growth Factor-1 and Dopamine: a Target for Neurodevelopmental Toxins and Thimerosal.
Molecular Psychiatry, July 2004.
Richard C. Deth, PhD [Northeastern University].
This study demonstrates how Thimerosal inhibits methylation, a central driver of cellular communication and development. Excerpt:
"The potent inhibition of this pathway [methylation] by ethanol, lead, mercury, aluminum, and thimerosal suggests it may be an important target of neurodevelopmental toxins."
8.  Neuroglial Activation and Neuroinflammation in the Brain of Patients with Autism.
Annals of Neurology, Feb 2005.
Diana L. Vargas, MD [Johns Hopkins University].
This study, performed independently and using a different methodology than Dr. Herbert (see above) reached the same conclusion: the brains of autistic children are suffering from inflammation. Excerpt:
"Because this neuroinflammatory process appears to be associated with an ongoing and chronic mechanism of CNS dysfunction, potential therapeutic interventions should focus on the control of its detrimental effects and thereby eventually modify the clinical course of autism."
9.  A Two-Phased Population Epidemiological Study of the Safety of Thimerosal-Containing Vaccines: a Follow-up Analysis.
Medical Science Monitor, April 2005.
Mark Geier, M.D., Ph.D., David A. Geier.
This follow-up study, using the CDC's own data, concluded there is a clear and obvious correlation between thimerosal-containing vaccines (TCVs) and neurodevelopmental disorders (NDs). Excerpt:
"This study showed that exposure to mercury from TCVs administered in the US was a consistent significant risk factor for the development of NDs."
10.  National Autism Prevalence Trends From United States Special Education Data.
Pediatrics, March 2005.
Craig J. Newschaffer, PhD [Johns Hopkins University].
This study shows that the rise in the incidence of autism is real and that the greatest increase took place between 1987 and 1992, which matches the timing of the near-tripling of mercury in pediatric vaccines.
11.  Retrograde Degeneration of Neurite Membrane Structural Integrity of Nerve Growth In Vitro Exposure to Mercury.
NeuroReport, 2001.
Christopher Leong, MD [University of Calgary].
This study shows how mercury damages brain cells.
