The effects of nutrition on the process of demyelination
By Elise Handley
University of Colorado
BPDII is defined as at least 1 hypomanic disorder and one major depressive episodeBPDI vs. BPDII
They differed from control in intracranial volume, adjusted ventricular volume, frontal fluid percent, and temporal fluid percent
There was also a trend in decreased head circumference11Friedman et al. (1999)
Electron dense heterochromatin
Granular ER in the cytoplasm
Free ribosomes, mitochondria etc.
Swelling of cytoplasm and organelles
Clumping of heterochromatin
Decreased nuclear size
All signs were consistent with programmed cell death in oligodendrocytes
Myelinated fibers had various changesNormal Brains vs. BPD Brains
This resulted in the selective killing of oligodendrocytes
The elevation in glutamate may be due to a thinning in the astrocyte population.
Another possibility is that NO (which is a ROS) levels increased
NO is known to damage oligodendrocytesHow did demyelination occur?
Luteolin was the “most potent” flavonoid tested, but quercetin, fisetin, and apigenin did inhibit myelin phagocytosis at higher concentrationsDid flavonoids help?
EPA affected the expression of proteolipid proteins (PLP) by means of accelerating the developmental expression, while AA caused no significant changesPolyunsaturated Fatty Acids
This means that use a switch to a Th2 pathway may aggravate these illnesses
There is decreased incidence of allergic disease in patients with MSThe Th-2 switch
More research is needed in this field
Both vitamin A and D have been shown to suppress EAE, and vitamin D3 has been shown to enhance the Th2 cell development (Racke and Racke 2002).
Thus, these treatments may be effective in the fight against BPDThe results
