Background:
The Consortium for Brain Fatty Acids (CFBFA)
is an outcome of the International Workshop on “Brain Uptake and Utilization
of Fatty Acids: Application to Peroxisomal Biogenesis Diseases,” March 2-4,
2000, Holiday Inn Bethesda, Bethesda, Maryland. The workshop was
held under the auspices of the Kennedy Krieger Research Institute, Baltimore,
Maryland; the Omega-3 Research Institute, Inc., Bethesda, Maryland; and the
Department of Neurology, Johns Hopkins University School of Medicine,
Baltimore, Maryland and was supported by a grant from the National Institute
of Neurological Diseases and Stroke, the Office of Rare Diseases and the
National Institute of Diabetes, and Digestive and Kidney Diseases. Other
sponsors included the BASF Corporation, BodyBio Corporation, Laxdale, Ltd.,
Martek Biosciences, Inc., Mead Johnson Nutritionals, Nordic Naturals, Ocean Nutrition Canada, Ltd., OmegaTech, Inc., Roche Vitamins, Inc.,
Ross Products Div. Abbott Laboratories, Scientific Hospital Supplies and
United Leukodystrophies Foundation.
Recent basic and clinical
research results indicate that long chain omega-3 polyunsaturated fatty acids
(PUFA) such as eicosapentaenoic acid (EPA, 20:5 n-3); docosahexaenoic acid (DHA,
22:6n-3) and arachidonic acid, AA, 20:4n-6, and their derivatives may play
important physiologic roles in mood and neurodegenerative disorders.
Examples are bipolar disorder and unipolar depression; schizophrenia;
brain developmental disorders (such as peroxisomal biogenesis disorders,
autism and attention deficit-hyperactivity disorder); neurodegenerative
diseases of aging including Alzheimer’s disease and brain cancers. The specialized expertise required for working with fatty acids
rendered the establishment of this resource imperative. The specialized expertise provided by this Consortium is required for
understanding some of the issues highlighted at the above workshop. For example, general areas identified as areas in need of further
research are a) fatty acid transport through membranes such as the
cerebrovascular endotheliun or blood-brain barrier (BBB) in the developing and
mature brain, b) shuttling of fatty acids among the BBB, oligodendrocytes,
astrocytes and neurons; c) intermediary metabolism of fatty acids, especially
essential PUFA, in oligodendrocytes, astrocytes and neurons in the developing
and adult brain; d) brain functions of PUFA including possible role in signal
transduction; e) development of new non-invasive methods for quantitation of
PUFA and phospholipids in the live human brain by use of animal models of
disease; f) diagnosis of disease states and profiling of PUFA in the liver,
plasma, erythrocyte membranes and the brain; e) assessment of potential
preventive and therapeutic interventions in the above and other disease, etc.

derived from the above-mentioned workshop).
