Why Johnny Can't Fucosylate

Major news about one of my favorite molecules, l-fucose. In addition to being part of the antigenic structure of the H antigen found in blood group O, fucose is now garnering attention as an important component in learning. Although neurophysiology spends quite a bit of time looking at the neurosynaptic junction (the gap between two nerve cells, where nerve conduction occurs) most of the emphasis is on the neurotransmitters (such as serotonin and dopamine) that can jump the gap. However, what goes into holding the synapse together may be as important a factor in cognition and learning as what jumps across the synapse. And that appears to be lectin-like receptors on one side of the nerve synapse which bind to fucose as a ligand on the other. In other words your nerves have a sweet tooth for fucose. Reaction in the brain involving fucose skyrocket during periods of intense learning. And human milk is a very rich source of the sugar, with amounts far higher than all other species. The sugar content of human milk varies by ABO blood type and secretor status which makes me want to do a study looking at learning differences along blood group and secretor status in breast fed and bottle fed children. The fucosyltransferase enzymes FUT1, FUT2 and FUT3 are very intimately involved in determining ABO, secretor and Lewis blood types and recent research has linked serum B12 levels (another important player in proper nerve function) to the FUT2 (secretor) gene. Fucose and fucosylation have a big role in ontogeny (the origin and the development of an organism from the fertilized egg to its mature form) via it's role in the development of the Lewis X antigen (FUT9) which supports cell-to-cell-adhesion in embryos. Lewis X expression in the brain is in turn controlled by the PAX6 gene, which regulates many elements of nerve growth in addition to forming the architecture of the iris. The link between PAX6 and Lewis X (FUT9) may explain why a recent study showed that at least some aspects of personality were determined by the genetics of iris formation. Close-up pictures were taken of the study participants' irises, and they also filled out a questionnaire about their personalities. The researchers looked at crypts (pits) and contraction furrows (lines curving around the outer edge of the iris), which are formed when pupils dilate. It was found that those with more crypts were likely to be tender, warm and trusting, while those with more furrows were more likely to be neurotic, impulsive and give in to cravings. PAX6 is gene that helps regulate embryonic differentiation. PAX6 also has some interesting effects on adrenal and pancreatic function as well as norepinephrine expression in the gut via the enteric nervous system. Maybe there's a future in medicine for the iris after all. Going forward, I predict that soon the best thing to use in kids who are learning-challenged will not be the usual suspects like Ritalin or SSRIs, but rather glycomic agents from the diet that enhance fucosylation. These drugs do enhance the function or persistence of neurotransmitters, but fucosylation enhancers seem to enhance the stability of the entire neural network. It makes no sense to up-regulate neurotransmitters if you haven't insured that the nerves are holding to each other in the first place. Of course, most of the old blood typers know that Bladderwrack (Fucus vesiculosis) is a decent source of fucose. Schizophrenia, gluten, and low-carbohydrate, ketogenic diets We report the unexpected resolution of longstanding schizophrenic symptoms after starting a low-carbohydrate, ketogenic diet. After a review of the literature, possible reasons for this include the metabolic consequences from the elimination of gluten from the diet, and the modulation of the disease of schizophrenia at the cellular level.
