    ALZHEIMER DISEASE;
    Polypeptide protects brain neurons in aluminum neurotoxicosis


    Hypothalamic proline-rich polypeptide protects brain neurons in
    aluminum neurotoxicosis.

    According to recent research from Armenia, "The damaging effect of
    aluminum ions (Al) on the organism is widely investigated in clinics
    and experiments that indicate its role as a participant in the
    synthesis of precursors for amyloid proteins and as a potential agent
    in the etiology of Alzheimer disease.

    It has been shown that aluminum produces neurotoxic effects. We
    established that AlCl produces degenerative changes in the
    ultrastructure of Hasserian neurinoma cells in vitro and in L-929
    fibroblast cells."

    "Proline-rich peptide-1 (PRP-1) isolated from neurosecretory granules
    of bovine neurohypophysis is a potent antineurodegenerative agent
    against spinal cord hemisection and crush syndrome-induced
    neurodegeneration of brain and spinal cord neurons," reported A. A.
    Galoyan and colleagues at the M. Heratsi State Medical University in
    Armenia and the Russian Academy of Sciences. "PRP-1 is one of the
    neurotrophic brain factors. By electron microscopic study of the rat
    hippocampus and other tissues, we succeeded in visualizing the
    epithelioprotectory effect of PRP-1, contributing as a powerful agent
    in removal of aluminum accumulation in different tissues in
    experimental aluminum neurotoxicosis."

    Galoyan and associates published their study in Neurochemical
    Research (Hypothalamic proline-rich polypeptide protects brain
    neurons in aluminum neurotoxicosis. Neurochem Res,
    2004;29(7):1349-1357).
