Abstract

<p>La presente invención se relaciona con los sectores biomédicos y biofarmacéutico. Específicamente se refiere a un antígeno quimérico que comprende Ia combinación de las regiones amino y carboxilo terminales del péptido beta amiloide (Aβ), las regiones amino y carboxilo terminales de Ia proteína tau y un epítopo de células T. La composición farmacéutica que comprende este antígeno quimérico y al menos un adyuvante vacunal farmacéuticamente aceptable incrementa Ia eficacia de Ia inmunoterapia para Ia prevención y el tratamiento de Ia Enfermedad de Alzheimer (EA). El antígeno quimérico ejerce su acción mediante Ia estimulación de una respuesta humoral multiblanco con altos títulos de anticuerpos anti-Aβ y anti-tau simultáneamente. Con ello, se favorece Ia eliminación combinada de las especies tóxicas tanto de Aβ como de tau del cerebro lo que previene o mejora significativamente los síntomas clínicos y neuropatología de Ia EA.</p>
