  5. 3. Amyloid precursor protein with the Alzheimer´s disease 670/671 mutation : animal and cellular models

    Author : Ewa Kloskowska; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The amyloid precursor protein (APP) and it s derivatives play a key role in the pathogenesis of Alzheimer s disease (AD), which is characterized by the presence of multiple aggregates of an APP proteolytic product, Ab, and tau protein in the brains of affected patients. Clinically the disease is manifested by a progressive loss of memory and executive functions. READ MORE
