Altered levels of microtubule proteins in brains of Alzheimer's disease patients

The amount of microtubule protein present in the total soluble protein from brains of Alzheimer's disease patients and from brains of non-Alzheimer age-matched controls, were determined by radioimmunoassay. No differences were found in the amount of tubulin or microtubule-associated protein MAP2 present in either group. However, the amount of tau protein or MAP1 from the brains of Alzheimer's disease patients was about half of that present in their control counterparts.Supported by Grants from the Comisión Asesora para el Desarrollo Tecnológico y Científico and Fondo de Investigaciones Sanitarias.Peer reviewe
