Abstract

Al3+, Fe3+, and Zn2+ ions can disturb microtubule assembly from tubulin and microtubuleassociated proteins in rat brain. The main structural forms of these microtubules are rings and tangled bundles. These structures are formed only in the presence of Al3+ and Fe3+ ions. Therefore, Zn2+ ions can be excluded from possible causes of structural abnormalities in microtubules during Alzheimer’s disease. Al3+ ions are the most probable etiological cause of Alzheimer’s disease. The concentration of Al3+ ions affecting the structure of microtubules is one order of magnitude lower than that of Fe3+ ions (10 and 100 μM, respectively), which corresponds to their brain concentration reported in Alzheimer’s disease.
